Alfred Bernhard Nobel


Alfred Bernhard Nobel (21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, innovator, and armaments manufacturer.

Alfred Bernhard Nobel

Known for inventing dynamite, Nobel also owned Bofors (Bofors AB is a Swedish arms manufacturing company. The name has been associated with the iron industry and artillery manufacturing for more than 350 years.), which he had redirected from its previous role as primarily an iron and steel producer to a major manufacturer of cannon and other armaments. Nobel held 355 different patents, dynamite being the most famous. After reading a premature obituary which condemned him for profiting from the sales of arms, he bequeathed his fortune to institute the Nobel Prizes. The synthetic element nobelium was named after him. His name also survives in modern-day companies such as Dynamit Nobel and AkzoNobel, which are descendants of mergers with companies Nobel himself established.

Life and career
Born in Stockholm, Alfred Nobel was the third son of Immanuel Nobel (1801–1872), an inventor and engineer, and Carolina Andriette (Ahlsell) Nobel (1805–1889). The couple married in 1827 and had eight children. The family was impoverished, and only Alfred and his three brothers survived past childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702), and in his turn the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age. Alfred Nobel's interest in technology was inherited from his father, an alumnus of Royal Institute of Technology in Stockholm.
Following various business failures, Nobel's father moved to Saint Petersburg in 1837 and grew successful there as a manufacturer of machine tools and explosives. He invented modern plywood and started work on the "torpedo". In 1842, the family joined him in the city. Now prosperous, his parents were able to send Nobel to private tutors and the boy excelled in his studies, particularly in chemistry and languages, achieving fluency in English, French, German and Russian. For 18 months, from 1841 to 1842, Nobel went to the only school he ever attended as a child, the Jacobs Apologistic School in Stockholm.
As a young man, Nobel studied with chemist Nikolai Zinin; then, in 1850, went to Paris to further the work. There he met Ascanio Sobrero, who had invented nitroglycerin three years before. Sobrero strongly opposed the use of nitroglycerin, as it was unpredictable, exploding when subjected to heat or pressure. But Nobel became interested in finding a way to control and use nitroglycerin as a commercially usable explosive, as it had much more power than gunpowder. At age 18, he went to the United States for four years to study chemistry, collaborating for a short period under inventor John Ericsson, who designed the American Civil War ironclad USS Monitor. Nobel filed his first patent, an English patent for a gas meter, in 1857, while his first Swedish patent, which he received in 1863, was on 'ways to prepare gunpowder'.
The family factory produced armaments for the Crimean War (1853–1856); but, had difficulty switching back to regular domestic production when the fighting ended and they filed for bankruptcy. In 1859, Nobel's father left his factory in the care of the second son, Ludvig Nobel (1831–1888), who greatly improved the business. Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerine (discovered in 1847 by Ascanio Sobrero, one of his fellow students under Théophile-Jules Pelouze at the University of Paris). Nobel invented a detonator in 1863; and, in 1865, he designed the blasting cap.
On 3 September 1864, a shed, used for the preparation of nitroglycerin, exploded at the factory in Heleneborg, Stockholm, killing five people, including Nobel's younger brother Emil. Dogged by more minor accidents but unfazed, Nobel went on to build further factories, focusing on improving the stability of the explosives he was developing. Nobel invented dynamite in 1867, a substance easier and safer to handle than the more unstable nitroglycerin. Dynamite was patented in the US and the UK and was used extensively in mining and the building of transport networks internationally. In 1875 Nobel invented gelignite, more stable and powerful than dynamite, and in 1887 patented ballistite, a predecessor of cordite.
Nobel was elected a member of the Royal Swedish Academy of Sciences in 1884, the same institution that would later select laureates for two of the Nobel prizes, and he received an honorary doctorate from Uppsala University in 1893.

Nobel's brothers Ludvig and Robert exploited oilfields along the Caspian Sea and became hugely rich in their own right. Nobel invested in these and amassed great wealth through the development of these new oil regions. During his life Nobel issued 355 patents internationally and by his death his business had established more than 90 armaments factories, despite his belief in pacifism.
In 1888, the death of his brother Ludvig caused several newspapers to publish obituaries of Alfred in error. A French obituary stated "Le marchand de la mort est mort" ("The merchant of death is dead").

Death
Accused of “high treason against France” for selling Ballistite to Italy, Nobel moved from Paris to Sanremo, Italy in 1891. On December 10, 1896, Alfred Nobel succumbed to a lingering heart ailment, suffered a stroke, and died. Unbeknownst to his family, friends or colleagues, he had left most of his wealth in trust, in order to fund the awards that would become known as the Nobel Prizes. He is buried in Norra begravningsplatsen in Stockholm.

Inventions
Nobel found that when nitroglycerin was incorporated in an absorbent inert substance like kieselguhr (diatomaceous earth) it became safer and more convenient to handle, and this mixture he patented in 1867 as 'dynamite'. Nobel demonstrated his explosive for the first time that year, at a quarry in Redhill, Surrey, England. In order to help reestablish his name and improve the image of his business from the earlier controversies associated with the dangerous explosives, Nobel had also considered naming the highly powerful substance "Nobel's Safety Powder", but settled with Dynamite instead, referring to the Greek word for "power" .

Nobel later on combined nitroglycerin with various nitrocellulose compounds, similar to collodion, but settled on a more efficient recipe combining another nitrate explosive, and obtained a transparent, jelly-like substance, which was a more powerful explosive than dynamite. 'Gelignite', or blasting gelatin, as it was named, was patented in 1876; and was followed by a host of similar combinations, modified by the addition of potassium nitrate and various other substances.

Gelignite was more stable, transportable and conveniently formed to fit into bored holes, like those used in drilling and mining, than the previously used compounds and was adopted as the standard technology for mining in the Age of Engineering bringing Nobel a great amount of financial success, though at a significant cost to his health. An offshoot of this research resulted in Nobel's invention of ballistite, the precursor of many modern smokeless powder explosives and still used as a rocket propellant.


Nobel Prizes
In 1888 Alfred's brother Ludvig died while visiting Cannes and a French newspaper erroneously published Alfred's obituary. It condemned him for his invention of dynamite and is said to have brought about his decision to leave a better legacy after his death. The obituary stated, Le marchand de la mort est mort ("The merchant of death is dead") and went on to say, "Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday." Alfred (who never had a wife or children) was disappointed with what he read and concerned with how he would be remembered.


Nobel Prize

On 27 November 1895, at the Swedish-Norwegian Club in Paris, Nobel signed his last will and testament and set aside the bulk of his estate to establish the Nobel Prizes, to be awarded annually without distinction of nationality. After taxes and bequests to individuals, Nobel's will allocated 94% of his total assets, 31,225,000 Swedish kronor, to establish the five Nobel Prizes. This converted to £1,687,837 (GBP) at the time. In 2012, the capital was worth around SEK 3.1 billion (USD 472 million, EUR 337 million), which is almost twice the amount of the initial capital, taking inflation into account.

Nobel Prize Award Ceremony, Stockholm 2007

The first three of these prizes are awarded for eminence in physical science, in chemistry and in medical science or physiology; the fourth is for literary work "in an ideal direction" and the fifth prize is to be given to the person or society that renders the greatest service to the cause of international fraternity, in the suppression or reduction of standing armies, or in the establishment or furtherance of peace congresses.
The formulation for the literary prize being given for a work "in an ideal direction" (i idealisk riktning in Swedish), is cryptic and has caused much confusion. For many years, the Swedish Academy interpreted "ideal" as "idealistic" (idealistisk) and used it as a reason not to give the prize to important but less romantic authors, such as Henrik Ibsen and Leo Tolstoy. This interpretation has since been revised, and the prize has been awarded to, for example, Dario Fo and José Saramago, who do not belong to the camp of literary idealism.
There was room for interpretation by the bodies he had named for deciding on the physical sciences and chemistry prizes, given that he had not consulted them before making the will. In his one-page testament, he stipulated that the money go to discoveries or inventions in the physical sciences and to discoveries or improvements in chemistry. He had opened the door to technological awards, but had not left instructions on how to deal with the distinction between science and technology. Since the deciding bodies he had chosen were more concerned with the former, the prizes went to scientists more often than engineers, technicians or other inventors.
In 2001, Alfred Nobel's great-great-nephew, Peter Nobel (b. 1931), asked the Bank of Sweden to differentiate its award to economists given "in Alfred Nobel's memory" from the five other awards. This request added to the controversy over whether the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel is actually a legitimate "Nobel Prize".

SIR ISAAC NEWTON

Portrait of Sir Issac Newton by Jean-Leon Huens.
Newton, Sir Isaac (1642-1727), mathematician and physicist, one of the foremost scientific intellects of all time. Born at Woolsthorpe, near Grantham in Lincolnshire, where he attended school, he entered Cambridge University in 1661; he was elected a Fellow of Trinity College in 1667, and Lucasian Professor of Mathematics in 1669. He remained at the university, lecturing in most years, until 1696. Of these Cambridge years, in which Newton was at the height of his creative power, he singled out 1665-1666 (spent largely in Lincolnshire because of plague in Cambridge) as "the prime of my age for invention". During two to three years of intense mental effort he prepared Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) commonly known as the Principia, although this was not published until 1687.

Portrait of Newton in 1689 by Godfrey Kneller
As a firm opponent of the attempt by King James II to make the universities into Catholic institutions, Newton was elected Member of Parliament for the University of Cambridge to the Convention Parliament of 1689, and sat again in 1701-1702. Meanwhile, in 1696 he had moved to London as Warden of the Royal Mint. He became Master of the Mint in 1699, an office he retained to his death. He was elected a Fellow of the Royal Society of London in 1671, and in 1703 he became President, being annually re-elected for the rest of his life. His major work, Opticks, appeared the next year; he was knighted in Cambridge in 1705.
Newton in a 1702 portrait by Godfrey Kneller
As Newtonian science became increasingly accepted on the Continent, and especially after a general peace was restored in 1714, following the War of the Spanish Succession, Newton became the most highly esteemed natural philosopher in Europe. His last decades were passed in revising his major works, polishing his studies of ancient history, and defending himself against critics, as well as carrying out his official duties. Newton was modest, diffident, and a man of simple tastes. He was angered by criticism or opposition, and harboured resentment; he was harsh towards enemies but generous to friends. In government, and at the Royal Society, he proved an able administrator. He never married and lived modestly, but was buried with great pomp in Westminster Abbey.

Newton has been regarded for almost 300 years as the founding examplar of modern physical science, his achievements in experimental investigation being as innovative as those in mathematical research. With equal, if not greater, energy and originality he also plunged into chemistry, the early history of Western civilization, and theology; among his special studies was an investigation of the form and dimensions, as described in the Bible, of Solomon's Temple in Jerusalem.

OPTICS
In 1664, while still a student, Newton read recent work on optics and light by the English physicists Robert Boyle and Robert Hooke; he also studied both the mathematics and the physics of the French philosopher and scientist René Descartes. He investigated the refraction of light by a glass prism; developing over a few years a series of increasingly elaborate, refined, and exact experiments, Newton discovered measurable, mathematical patterns in the phenomenon of colour. He found white light to be a mixture of infinitely varied coloured rays (manifest in the rainbow and the spectrum), each ray definable by the angle through which it is refracted on entering or leaving a given transparent medium. 
Sir Isaac Newton discovered the phenomenon of light dispersion in 1666, the splitting of white light into colours by a prism.
He correlated this notion with his study of the interference colours of thin films (for example, of oil on water, or soap bubbles), using a simple technique of extreme acuity to measure the thickness of such films. He held that light consisted of streams of minute particles. From his experiments he could infer the magnitudes of the transparent "corpuscles" forming the surfaces of bodies, which, according to their dimensions, so interacted with white light as to reflect, selectively, the different observed colours of those surfaces.
dispersion of colours by the prism
The roots of these unconventional ideas were with Newton by about 1668; when first expressed (tersely and partially) in public in 1672 and 1675, they provoked hostile criticism, mainly because colours were thought to be modified forms of homogeneous white light. Doubts, and Newton's rejoinders, were printed in the learned journals. Notably, the scepticism of Christiaan Huygens and the failure of the French physicist Edmé Mariotte to duplicate Newton's refraction experiments in 1681 set scientists on the Continent against him for a generation. The publication of Opticks, largely written by 1692, was delayed by Newton until the critics were dead. The book was still imperfect: the colours of diffraction defeated Newton. Nevertheless, Opticks established itself, from about 1715, as a model of the interweaving of theory with quantitative experimentation.

MATHEMATICS
In mathematics too, early brilliance appeared in Newton's student notes. He may have learnt geometry at school, though he always spoke of himself as self-taught; certainly he advanced through studying the writings of his compatriots William Oughtred and John Wallis, and of Descartes and the Dutch school. Newton made contributions to all branches of mathematics then studied, but is especially famous for his solutions to the contemporary problems in analytical geometry of drawing tangents to curves (differentiation) and defining areas bounded by curves (integration). Not only did Newton discover that these problems were inverse to each other, but he discovered general methods of resolving problems of curvature, embraced in his "method of fluxions" and "inverse method of fluxions", respectively equivalent to Leibniz's later differential and integral calculus. Newton used the term "fluxion" (from Latin meaning "flow") because he imagined a quantity "flowing" from one magnitude to another. Fluxions were expressed algebraically, as Leibniz's differentials were, but Newton made extensive use also (especially in the Principia) of analogous geometrical arguments. Late in life, Newton expressed regret for the algebraic style of recent mathematical progress, preferring the geometrical method of the Classical Greeks, which he regarded as clearer and more rigorous.
Newton's work on pure mathematics was virtually hidden from all but his correspondents until 1704, when he published, with Opticks, a tract on the quadrature of curves (integration) and another on the classification of the cubic curves. His Cambridge lectures, delivered from about 1673 to 1683, were published in 1707.

In the 1690s Newton's friends proclaimed the priority of Newton's methods of fluxions. Supporters of Leibniz asserted that he had communicated the differential method to Newton, although Leibniz had claimed no such thing. Newtonians then asserted, rightly, that Leibniz had seen papers of Newton's during a London visit in 1676; in reality, Leibniz had taken no notice of material on fluxions. A violent dispute sprang up, part public, part private, extended by Leibniz to attacks on Newton's theory of gravitation and his ideas about God and creation; it was not ended even by Leibniz's death in 1716. The dispute delayed the reception of Newtonian science on the Continent, and dissuaded British mathematicians from sharing the researches of Continental colleagues for a century.

MECHANICS AND GRAVITATION
According to the well-known story, it was on seeing an apple fall in his orchard at some time during 1665 or 1666 that Newton conceived that the same force governed the motion of the Moon and the apple. He calculated the force needed to hold the Moon in its orbit, as compared with the force pulling an object to the ground. He also calculated the centripetal force needed to hold a stone in a sling, and the relation between the length of a pendulum and the time of its swing. These early explorations were not soon exploited by Newton, though he studied astronomy and the problems of planetary motion.
Newton, apple and gravity
Correspondence with Hooke (1679-1680) redirected Newton to the problem of the path of a body subjected to a centrally directed force that varies as the inverse square of the distance; he determined it to be an ellipse, so informing Edmond Halley in August 1684. Halley's interest led Newton to demonstrate the relationship afresh, to compose a brief tract on mechanics, and finally to write the Principia.
Book I of the Principia states the foundations of the science of mechanics, developing upon them the mathematics of orbital motion round centres of force. Newton identified gravitation as the fundamental force controlling the motions of the celestial bodies. He never found its cause. To contemporaries who found the idea of attractions across empty space unintelligible, he conceded that they might prove to be caused by the impacts of unseen particles.
Book II inaugurates the theory of fluids: Newton solves problems of fluids in movement and of motion through fluids. From the density of air he calculated the speed of sound waves.
Book III shows the law of gravitation at work in the universe: Newton demonstrates it from the revolutions of the six known planets, including the Earth, and their satellites. However, he could never quite perfect the difficult theory of the Moon's motion. Comets were shown to obey the same law; in later editions, Newton added conjectures on the possibility of their return. He calculated the relative masses of heavenly bodies from their gravitational forces, and the oblateness of Earth and Jupiter, already observed. He explained tidal ebb and flow and the precession of the equinoxes from the forces exerted by the Sun and Moon. All this was done by exact computation.
Newton's work in mechanics was accepted at once in Britain, and universally after half a century. Since then it has been ranked among humanity's greatest achievements in abstract thought. It was extended and perfected by others, notably Pierre Simon de Laplace, without changing its basis and it survived into the late 19th century before it began to show signs of failing. See Quantum Theory; Relativity.

ALCHEMY AND CHEMISTRY
Newton left a mass of manuscripts on the subjects of alchemy and chemistry, then closely related topics. Most of these were extracts from books, bibliographies, dictionaries, and so on, but a few are original. He began intensive experimentation in 1669, continuing till he left Cambridge, seeking to unravel the meaning that he hoped was hidden in alchemical obscurity and mysticism. He sought understanding of the nature and structure of all matter, formed from the "solid, massy, hard, impenetrable, movable particles" that he believed God had created. Most importantly in the "Queries" appended to "Opticks" and in the essay "On the Nature of Acids" (1710), Newton published an incomplete theory of chemical force, concealing his exploration of the alchemists, which became known a century after his death.

NIKOLA TESLA : THE BIOGRAPHY



Nikola Tesla contributed to the development of the alternating-current electrical system that's widely used today and discovered the rotating magnetic field (the basis of most AC machinery).

Nikola Tesla aged 34, (in 1890)
Synopsis

Inventor Nikola Tesla was born in July of 1856, in what is now Croatia. He came to the United States in 1884 and briefly worked with Thomas Edison before the two parted ways. He sold several patent rights, including those to his alternating-current machinery, to George Westinghouse. His 1891 invention, the "Tesla coil," is still used in radio technology today. Tesla died in New York City on January 7, 1943.


Early Life

Nikola Tesla was born on July 10, 1856, in what is now Smiljan, Croatia. Tesla's interest in electrical invention was spurred by his mother, Djuka Mandic, who invented small household appliances in her spare time while her son was growing up. Tesla's father, Milutin Tesla, was a priest and a writer, and he pushed for his son to join the priesthood. But Nikola's interests lay squarely in the sciences. After studying at the Realschule, Karlstadt (later renamed the Johann-Rudolph-Glauber Realschule Karlstadt); the Polytechnic Institute in Graz, Austria; and the University of Prague during the 1870s, Tesla moved to Budapest, where for a time he worked at the Central Telephone Exchange. It was while in Budapest that the idea for the induction motor first came to Tesla, but after several years of trying to gain interest in his invention, at age 28 Tesla decided to leave Europe for America.


Famed Inventor

In 1884 Tesla arrived the United States with little more than the clothes on his back and a letter of introduction to famed inventor and business mogul Thomas Edison, whose DC-based electrical works were fast becoming the standard in the country. Edison hired Tesla, and the two men were soon working tirelessly alongside each other, making improvements to Edison's inventions. However, several months later, the two parted ways due to a conflicting business-scientific relationship, attributed by historians to their incredibly different personalities: While Edison was a power figure who focused on marketing and financial success, Tesla was commercially out-of-tune and somewhat vulnerable.

After parting ways with Edison, in 1885 Tesla received funding for the Tesla Electric Light Company and was tasked by his investors to develop improved arc lighting. After successfully doing so, however, Tesla was forced out of the venture and for a time had to work as a manual laborer in order to survive. His luck changed in 1887, when he was able to find interest in his AC electrical system and funding for his new Tesla Electric Company. Setting straight to work, by the end of the year, Tesla had successfully filed several patents for AC-based inventions.   

Nikola Tesla alternating current

 Tesla's AC system eventually caught the attention of American engineer and business man George Westinghouse, who was seeking a solution to supplying the nation with long-distance power. Convinced that Tesla's inventions would help him achieve this, in 1888 he purchased his patents for $60,000 in cash and stock in the Westinghouse Corporation. As interest in an alternating-current system grew, Tesla and Westinghouse were put in direct competition with Thomas Edison, who was intent on selling his direct-current system to the nation. A negative-press campaign was soon waged by Edison, in an attempt to undermine interest in AC power. Tesla, for his part, continued in his work and would patent several more inventions during this period, including the "Tesla coil," which laid the foundation for wireless technologies and is still used in radio technology today.

Unfortunately for Thomas Edison, the Westinghouse Corporation was chosen to supply the lighting at the 1893 World's Columbian Exposition in Chicago, and Tesla conducted demonstrations of his AC system there. Two years later, in 1895, Tesla designed what was among the first AC hydroelectric power plants in the United States, at Niagara Falls. The following year, it was used to power the city of Buffalo, New York, a feat that was highly publicized throughout the world. With its repeat successes and favorable press, the alternating-current system would quickly become the preeminent power system of the 20th century, and it has remained the worldwide standard ever since.

In addition to his AC system and coil, throughout his career, Tesla discovered, designed and developed ideas for a number of other important inventions—most of which were officially patented by other inventors—including dynamos (electrical generators similar to batteries) and the induction motor. He was also a pioneer in the discovery of radar technology, X-ray technology, remote control and the rotating magnetic field—the basis of most AC machinery.

The Fall from Grace

Having become obsessed with the wireless transmission of energy, around 1900 Nikola set to work on his boldest project yet: to build a global, wireless communication system—to be transmitted through a large electrical tower—for sharing information and providing free electricity throughout the world. With funding from a group of investors that included financial giant J. P. Morgan, in 1901 Tesla began work on the project in earnest, designing and building a lab with a power plant and a massive transmission tower on a site on Long Island, New York, that became known as Wardenclyffe. 

Nikola Tesla's Wardenclyffe Tower

However, when doubts arose among his investors about the plausibility of Tesla's system and his rival, Guglielmo Marconi—with the financial support of Andrew Carnegie and Thomas Edison—continued to make great advances with his own radio technologies, Tesla had no choice but to abandon the project. The Wardenclyffe staff was laid off in 1906 and by 1915 the site had fallen into foreclosure. Two years later Tesla declared bankruptcy and the tower was dismantled and sold for scrap to help pay the debts he had accrued.



Death and Legacy

After suffering a nervous breakdown, Tesla eventually returned to work, primarily as a consultant. But as time went on, his ideas became progressively more outlandish and impractical. He also grew increasingly eccentric, devoting much of his time to the care of wild pigeons in New York City's parks. He even drew the attention of the FBI with his talk of building a powerful "death beam," which had received some interest from the Soviet Union during World World II. 
Nikola Tesla, who died on January 7, 1943
Poor and reclusive, Nikola Tesla died on January 7, 1943, at the age of 86, in New York City, where he had lived for nearly 60 years. But the legacy of the work he left behind him lives on to this day.

WERNHER VON BRAUN: FROM NAZI TO NASA

On Thursday, September 20, 1945, Wernher von Braun arrived at Fort Strong. The small military site on the northern tip of Boston Harbour's Long Island was the processing point for Project Paperclip, the government programme under which hundreds of German scientists were brought into America. Von Braun filled out his paperwork that day as the inventor of the Nazi V-2 rocket, a member of the Nazi party, and a member of the SS who could be linked to the deaths of thousands of concentration camp prisoners. Two and a half decades later on Wednesday, July 16, 1969, von Braun stood in the firing room at Kennedy Spaceflight Centre and watched another of his rockets, the Saturn V, take the Apollo 11 crew to the Moon.

That he was responsible for both the deadly Nazi V-2 and NASA's majestic Saturn V makes Wernher von Braun a controversial historical figure. Some hold that his participation in the Nazi war effort necessitates classifying him as a villain. But while his actions during the Second World War were monstrous, he wasn't motivated by some inherent evil or personal belief in Nazi ideology. Von Braun was motivated by his childhood obsession with spaceflight, a somewhat uncritical patriotism, and a naive grasp of the ramifications of his actions in creating one of the War's deadliest weapons. How can we treat someone who brought technological triumph to two nations, in one case as a purveyor of death and destruction and in the other a bringer of wonder and inspiration?

The von Brauns
Wernher von Braun's lineage can be traced back to the Junkers, a social class of nobles that dominated the Prussian military officer corps, the landowning elite, and offices of civil service in the 19th and early 20th centuries.

The young Wernher von Braun 

High social standing was inherited or acquired through marriage, a legacy that typically gave Junkers a narrow and self-interested world view. Von Braun's father Magnus was a civil servant, a career that ensured the family had a certain quality of life. Raised in this privileged environment with a sense of his Junker heritage shaped von Braun at an early age into a proud and sometimes arrogant young man.
Wernher von Braun's love affair with space, which was at odds with his upbringing, began when his mother Emmy gave him a telescope for his thirteenth birthday. Looking up at the Moon and the stars, he was seized with a desire to travel into space; launching rockets and landing spacecraft, men, and possibly himself on the Moon became his life's goal. He devoured books about space travel and worked out mission plans of his own.
This obsession with spaceflight took a toll on his academics, as von Braun only applied himself to the subjects that would help him launch rockets. He excelled beyond his professors in maths and physics, eventually teaching classes and tutoring his peers. His grades in other courses, meanwhile, were largely satisfactory. Nevertheless, he was skipped ahead halfway through the twelfth grade to graduate high school a year early.

Rocketry, opportunity, and the Second World War
It was around this time that von Braun got his first hands-on experience with rockets as a member of the Verein fur Raumschiffahrt (VfR), an amateur rocket society. The VfR's activities caught the German Army's attention, and when a group of officers went to watch a launch in the spring of 1932, it was von Braun who stood out. Army Ordnance officer Walter Dornberger saw promise in the young engineer and offered him the opportunity to develop his rockets and explore their possible military applications on the Army's dime. Von Braun accepted Dornberger's offer and began his doctoral work in physics and engineering at the University of Berlin later that year.
In 1933, Adolf Hitler came to power. Still deeply engaged in his doctoral work, von Braun was only partially aware of the nationwide changes brought about by this new leadership. He was only 21 and by his own admission (albeit later in life) apolitical and somewhat disinterested in the world around him. He was patriotic, but rockets were his main concern.
Von Braun finished his dissertation in 1934. Titled "Design, Theoretical and Experimental Contributions to the Problem of the Liquid Fuel Rocket", its contents were deemed so important to the future of Germany's military that it was hidden under a new title, "Regarding Combustion Experiments", and transferred to the Army Ordnance's custody. Von Braun was just 22. Not long after, he began working for the Army on a variety of rocket programmes, among them the ballistic missile the Nazi Propaganda Ministry would eventually call Vergeltungswaffe-Zwei, Vengeance Weapon 2 or V-2.

Vergeltungswaffe-Zwei The V-2 Rocket

A cutaway drawing of a German V2 rocket

The Army increased funding for the V-2 programme throughout the 1930s. By the time the War broke out in 1939, von Braun was running a sizable operation at a dedicated rocket facility at Peenemunde. Sitting on the northern German island of Usedom, Peenemunde afforded von Braun's team the space to build, test, and launch their rockets harmlessly into the Baltic Sea.
But the V-2s that were launched towards London beginning in 1944 weren't built at Peenemunde. These rockets were built in underground factories near the central German town of Nordhausen - most famously at Mittelwerk, where construction was done by prisoners from the nearby Dora-Mittelbau concentration camp. Over 60,000 prisoners lived, worked, and died in the damp underground tunnels at Mittelwerk. Some succumbed to disease and malnutrition. Some were worked to death. Others were hanged publicly in group executions. The death rate rose so high that crematoriums became a necessity.
Von Braun visited Mittelwerk at least once; he was given a tour of the facility by SS guards in late 1943 when prisoners were still excavating tunnels. But just how this and any subsequent trips affected the young rocketeer is open to speculation. There are no records of von Braun planning or overseeing operations at Mittelwerk, even from a distance. It's possible that his boyhood disinterest in politics helped him either ignore or repress what he knew about Mittelwerk, or perhaps he was able to justify the deplorable conditions in his rockets' factory as a necessity of war. Years later, in America, von Braun called the V-2 his contribution to Germany's wartime arsenal. It was what any citizen was expected to do.
During his tenure developing the V-2, von Braun joined the Nazi party and became a member of the SS.

He also held on to his dream of landing men on the Moon. One night in early March of 1944, he drank too much at a party and spoke too freely in what he thought was just casual conversation. He told fellow party goers that he foresaw the war ending badly for Germany and added that all he'd ever wanted to do with his rockets was launch them into space. It was an admission akin to treason, which was a crime punishable by death. Von Braun was arrested weeks later, and while he was never incarcerated, it was his first indication that he wouldn't be safe in his home country when the war ended.
Von Braun was attracted by the opportunities America promised and suspected that the US military would support his continued research in rocketry. He had already decided that he wanted to surrender to and build rockets for America when he heard that Hitler was dead on May 1, 1945. Hiding with his fellow rocket engineers in Bavaria at the time, von Braun elected an emissary from the group, his younger brother Magnus, to go, find and surrender to American soldiers. Magnus did. By nightfall on May 2, Wernher von Braun was in the hands of American soldiers and within months the US government made him the offer he'd hoped for: military funding to develop an Americanised version of the V-2.

Finding fame in America
After working in relative obscurity in New Mexico for four years, von Braun and other former Peenemunders brought overseas under Project Paperclip were moved to the US Army's Redstone Arsenal in Huntsville, Alabama.

On March 22, 1952, von Braun introduced the American public to his vision of space exploration in the pages of Collier's Magazine. In a series of articles published over two years, he described how men would live and work in huge doughnut-shaped orbital space stations before setting off on missions to the Moon. He imagined spacecraft launching and gliding back to Earth daily. And he described, in detail, the rockets he would build to launch such missions. Americans met the man behind this compelling future on March 9, 1955 when von Braun appeared in the first episode of Walt Disney's Tomorrowland TV series. Viewers saw von Braun's vision come to life with stunning animation.
Von Braun brought the same vision to NASA when the agency absorbed his rocket group in 1960. Throughout the decade, he was pictured shaking hands with presidents, smiling with astronauts, and posing in front of the massive rockets that would launch them into space. And while NASA's path to the Moon ultimately deviated from von Braun's vision, he nevertheless achieved his boyhood dream in 1969.

Whatever celebrity von Braun achieve in America, it couldn't erase his Nazi past. But in the same way he covered or ignored his association with Mittelwerk, American leaders and administrators suppressed or deliberately misrepresented his past and emphasised his contributions to the nation's space programme and space exploration generally. He wasn't ostracised as an ex-Nazi; he was celebrated as the creator of the Saturn V.

Times of war
The circumstances surrounding von Braun's two greatest rocket triumphs were very different. The V-2 was built by prison labour and launched as an offensive weapon while the Saturn V was built by American aviation companies and launched with manned spacecraft to the Moon. But there's nevertheless a strong parallel: both rockets were built and launched in times of war. In both cases, von Braun followed the money and developed the technology he could to defeat an enemy, Allied soldiers in Europe and the Soviet Union in space. In neither case did he undertake his work for strong ideological reasons. He had no apparent moral quandary or crisis of conscience aligning himself with the Nazi party in the 1930s, nor did he labour over the decision to turn his back on his homeland and immigrate to America in 1945. The constant thread running through von Braun's life during both wars is his fixation on spaceflight.
The legacy von Braun has left behind will always be split between those who classify him as a villain and those who classify him as a visionary. Both might be true. He certainly exploited horrifying means to pursue his goals, but was unquestionably one of the most influential rocket engineers and spaceflight visionaries of the 20th century.

WERNHER VON BRAUN

Wernher Magnus Maximilian Freiherr von Braun (March 23, 1912 – June 16, 1977) was a German, later American, aerospace engineer and space architect credited with inventing the V-2 rocket for Nazi Germany and the Saturn V for the United States. He was one of the leading figures in the development of rocket technology in Nazi Germany, where he was a member of the Nazi Party and the SS. Following World War II, he was moved to the United States, along with about 1,500 other scientists, technicians, and engineers, as part of Operation Paperclip, where he developed the rockets that launched the United States' first space satellite Explorer 1, and the Apollo program manned lunar landings.

In his twenties and early thirties, von Braun worked in Germany's rocket development program, where he helped design and develop the V-2 rocket at Peenemünde during World War II. Following the war, von Braun worked for the United States Army on an intermediate-range ballistic missile (IRBM) program before his group was assimilated into NASA. Under NASA, he served as director of the newly formed Marshall Space Flight Center and as the chief architect of the Saturn V launch vehicle, the superbooster that propelled the Apollo spacecraft to the Moon. According to a NASA source, he is, "without doubt, the greatest rocket scientist in history", as well as the "Father of Rocket Science".[citation needed][6] In 1975, he received the National Medal of Science. He continued insisting on the human mission to Mars throughout his life.


His life
Wernher von Braun was born on 23 March 1912 in the small town of Wirsitz, Posen Province, German Empire (now Wyrzysk, Poland). He was the second of three sons. He belonged to a noble family, inheriting the German title of Freiherr (equivalent to Baron). His father, conservative civil servant Magnus Freiherr von Braun (1878–1972), served as a Minister of Agriculture in the Reich Cabinet during the Weimar Republic. His mother, Emmy von Quistorp (1886–1959), could trace her ancestry through both parents to medieval European royalty and was a descendant of Philip III of France, Valdemar I of Denmark, Robert III of Scotland, and Edward III of England. Von Braun had an older brother, Sigismund, and a younger brother, also named Magnus. After Wernher von Braun's Lutheran confirmation, his mother gave him a telescope, and he developed a passion for astronomy. The family moved to Berlin in 1915 where his father worked at the Ministry of the Interior. Here 12-year-old Wernher von Braun, inspired by speed records established by Max Valier and Fritz von Opel in rocket-propelled cars, caused a major disruption in a crowded street by detonating a toy wagon to which he had attached a number of fireworks. He was taken into custody by the local police until his father came to collect him.

Wernher von Braun was an accomplished amateur pianist who could play Beethoven and Bach from memory. He learned to play both the cello and the piano at an early age and at one time wanted to become a composer. He took lessons from the composer Paul Hindemith. The few pieces of von Braun’s youthful compositions that exist are reminiscent of Hindemith’s style.

Beginning in 1925, von Braun attended a boarding school at Ettersburg Castle near Weimar, where he did not do well in physics and mathematics. There he acquired a copy of By Rocket into Planetary Space (Die Rakete zu den Planetenräumen, 1923) by rocket pioneer Hermann Oberth. In 1928, his parents moved him to the Hermann-Lietz-Internat (also a residential school) on the East Frisian North Sea island of Spiekeroog. Space travel had always fascinated von Braun, and from then on he applied himself to physics and mathematics to pursue his interest in rocket engineering.

In 1930, he attended the Technische Hochschule Berlin, where he joined the Spaceflight Society (Verein für Raumschiffahrt or "VfR") and assisted Willy Ley in his liquid-fueled rocket motor tests in conjunction with Hermann Oberth. In spring 1932, he graduated from the Technische Hochschule Berlin (now Technical University of Berlin), with a diploma in mechanical engineering. His early exposure to rocketry convinced him that the exploration of space would require far more than applications of the current engineering technology. Wanting to learn more about physics, chemistry, and astronomy, von Braun entered the Friedrich-Wilhelm University of Berlin for post-graduate studies and graduated with a doctorate in physics in 1934. He also studied at ETH Zürich. Although he worked mainly on military rockets in his later years there, space travel remained his primary interest.

In 1930, von Braun attended a presentation given by Auguste Piccard. After the talk the young student approached the famous pioneer of high-altitude balloon flight, and stated to him: "You know, I plan on traveling to the Moon at some time." Piccard is said to have responded with encouraging words.

Working with the Nazis

In 1933, Von Braun was working on his creative doctorate when the National Socialist German Workers Party (NSDAP, or Nazi Party) came to power in a coalition government in Germany; rocketry almost immediately moved onto the national agenda. An artillery captain, Walter Dornberger, arranged an Ordnance Department research grant for von Braun, who then worked next to Dornberger's existing solid-fuel rocket test site at Kummersdorf. He was awarded a doctorate in physics (aerospace engineering) on July 27, 1934, from the University of Berlin for a thesis entitled "About Combustion Tests"; his doctoral supervisor was Erich Schumann. However, this thesis was only the public part of Von Braun's work. His actual full thesis, Construction, Theoretical, and Experimental Solution to the Problem of the Liquid Propellant Rocket (dated April 16, 1934) was kept classified by the army, and was not published until 1960. By the end of 1934, his group had successfully launched two liquid fuel rockets that rose to heights of 2.2 and 3.5 km (2 mi).

At the time, Germany was highly interested in American physicist Robert H. Goddard's research. Before 1939, German scientists occasionally contacted Goddard directly with technical questions. Wernher von Braun used Goddard's plans from various journals and incorporated them into the building of the Aggregat (A) series of rockets. The A-4 rocket would become well known as the V-2. In 1963, von Braun reflected on the history of rocketry, and said of Goddard's work: "His rockets ... may have been rather crude by present-day standards, but they blazed the trail and incorporated many features used in our most modern rockets and space vehicles."

Surrender to the Americans
The Soviet Army was about 160 km (99 mi) from Peenemünde in the spring of 1945 when Von Braun assembled his planning staff and asked them to decide how and to whom they should surrender. Afraid of the well-known Soviet cruelty to prisoners of war, von Braun and his staff decided to try to surrender to the Americans. Kammler had ordered relocation of his team to central Germany; however, a conflicting order from an army chief ordered them to join the army and fight. Deciding that Kammler's order was their best bet to defect to the Americans, von Braun fabricated documents and transported 500 of his affiliates to the area around Mittelwerk, where they resumed their work. For fear of their documents being destroyed by the SS, von Braun ordered the blueprints to be hidden in an abandoned mine shaft in the Harz mountain range.
While on an official trip in March, von Braun suffered a complicated fracture of his left arm and shoulder in a car accident after his driver fell asleep at the wheel. His injuries were serious, but he insisted that his arm be set in a cast so he could leave the hospital. Due to this neglect of the injury he had to be hospitalized again a month later where his bones had to be re-broken and re-aligned.
In April, as the Allied forces advanced deeper into Germany, Kammler ordered the engineering team to be moved by train into the town of Oberammergau in the Bavarian Alps where they were closely guarded by the SS with orders to execute the team if they were about to fall into enemy hands. However, Von Braun managed to convince SS Major Kummer to order the dispersion of the group into nearby villages so that they would not be an easy target for U.S. bombers.

Von Braun and a large number of the engineering team subsequently made it to Austria. On May 2, 1945, upon finding an American private from the U.S. 44th Infantry Division, Von Braun's brother and fellow rocket engineer, Magnus, approached the soldier on a bicycle, calling out in broken English: "My name is Magnus von Braun. My brother invented the V-2. We want to surrender."
The American high command was well aware of how important their catch was: von Braun had been at the top of the Black List, the code name for the list of German scientists and engineers targeted for immediate interrogation by U.S. military experts.
