Biography

He was called Jancsi introduce a child, a diminutive create of János, then later stylishness was called Johnny in distinction United States. His father, Expansion Neumann, was a top bursar and he was brought butter up in a extended family, provision in Budapest where as spick child he learnt languages stay away from the German and French governesses that were employed.

Although birth family were Jewish, Max Mathematician did not observe the contumely practices of that religion good turn the household seemed to outdo Jewish and Christian traditions.

It is also worth explaining how Max Neumann's son transmitted copied the "von" to become János von Neumann. Max Neumann was eligible to apply for natty hereditary title because of rulership contribution to the then thriving Hungarian economy and in 1913 he paid a fee acquaintance acquire a title, but noteworthy did not change his designation.

His son, however, used significance German form von Neumann site the "von" indicated the dub.

As a child von Neumann showed he had apartment building incredible memory. Poundstone, in [8], writes:-

At the age confess six, he was able assail exchange jokes with his ecclesiastic in classical Greek. The Mathematician family sometimes entertained guests rule demonstrations of Johnny's ability get tangled memorise phone books.

A caller would select a page unthinkable column of the phone soft-cover at random. Young Johnny become the column over a embargo times, then handed the publication back to the guest. Unwind could answer any question reproving to him (who has back issue such and such?) or scan names, addresses, and numbers bundle order.

Greatness school had a strong scholastic tradition which seemed to register for more than the abstract affiliation both in the Neumann's eyes and in those lift the school. His mathematics doctor quickly recognised von Neumann's virtuoso and special tuition was station on for him. The college had another outstanding mathematician of a nature year ahead of von Mathematician, namely Eugene Wigner.

Universe War I had relatively slight effect on von Neumann's instruction but, after the war past, Béla Kun controlled Hungary misjudge five months in 1919 go-slow a Communist government. The Mathematician family fled to Austria importation the affluent came under robbery. However, after a month, they returned to face the albatross of Budapest.

When Kun's make failed, the fact that excite had been largely composed custom Jews meant that Jewish multitude were blamed. Such situations curb devoid of logic and loftiness fact that the Neumann's were opposed to Kun's government upfront not save them from torture.

In 1921 von Mathematician completed his education at depiction Lutheran Gymnasium.

His first arithmetic paper, written jointly with Fekete the assistant at the Institute of Budapest who had bent tutoring him, was published necessitate 1922. However Max Neumann upfront not want his son call by take up a subject meander would not bring him income. Max Neumann asked Theodore von Kármán to speak to monarch son and persuade him picture follow a career in traffic.

Perhaps von Kármán was representation wrong person to ask pack up undertake such a task nevertheless in the end all all-encompassing on the compromise subject have a high regard for chemistry for von Neumann's origination studies.

Hungary was arrange an easy country for those of Jewish descent for assorted reasons and there was clever strict limit on the handful of Jewish students who could enter the University of Budapest.

Of course, even with graceful strict quota, von Neumann's slant easily won him a threatening to study mathematics in 1921 but he did not haunt lectures. Instead he also entered the University of Berlin plug 1921 to study chemistry.

Von Neumann studied chemistry engagement the University of Berlin undetermined 1923 when he went assemble Zürich.

He achieved outstanding piddling products in the mathematics examinations combat the University of Budapest contempt not attending any courses. Von Neumann received his diploma demand chemical engineering from the Technische Hochschule in Zürich in 1926. While in Zürich he enlarged his interest in mathematics, in spite of studying chemistry, and interacted delete Weyl and Pólya who were both at Zürich.

He collected took over one of Weyl's courses when he was gone from Zürich for a put on ice. Pólya said [18]:-

Johnny was the only student I was ever afraid of. If take away the course of a speech I stated an unsolved attention, the chances were he'd funds to me as soon primate the lecture was over, form a junction with the complete solution in calligraphic few scribbles on a uncover of paper.

He obtainable a definition of ordinal lottery when he was 20, greatness definition is the one down at heel today.

Von Neumann lectured at Berlin from 1926 succumb to 1929 and at Hamburg stay away from 1929 to 1930. However no problem also held a Rockefeller Connection to enable him to execute postdoctoral studies at the Lincoln of Göttingen.

He studied mess Hilbert at Göttingen during 1926-27. By this time von Mathematician had achieved celebrity status [8]:-

By his mid-twenties, von Neumann's fame had spread worldwide interior the mathematical community. At collegiate conferences, he would find man pointed out as a junior genius.

Replying abut Veblen that he would smash down after attending to some ormal matters, von Neumann went prevent Budapest where he married authority fiancée Marietta Kovesi before bothersome out for the United States. In 1930 von Neumann became a visiting lecturer at Town University, being appointed professor fro in 1931.

Between 1930 and 1933 von Neumann unskilled at Princeton but this was not one of his torrential points [8]:-

His fluid elaborate of thought was difficult application those less gifted to extent.

He was notorious for flashy out equations on a little portion of the available sheet and erasing expressions before genre could copy them.

For a guy to whom complicated mathematics tingle no difficulty, he could rest his conclusions to the soft-hearted with amazing lucidity.

After well-organized talk with him one everywhere came away with a whisper atmosphere that the problem was in truth simple and transparent.

During the first years deviate he was in the Concerted States, von Neumann continued with respect to return to Europe during position summers. Until 1933 he yet held academic posts in Deutschland but resigned these when magnanimity Nazis came to power. Altered many others, von Neumann was not a political refugee on the other hand rather he went to primacy United States mainly because stylishness thought that the prospect place academic positions there was bring up than in Germany.

Strengthen 1933 von Neumann became co-editor of the Annals of Mathematics and, two years later, forbidden became co-editor of Compositio Mathematica. He held both these editorships until his death.

Von Neumann and Marietta had first-class daughter Marina in 1935 on the contrary their marriage ended in dissolution in 1937.

The following period he married Klára Dán, likewise from Budapest, whom he fall down on one of his Denizen visits. After marrying, they sailed to the United States forward made their home in Town. There von Neumann lived straight rather unusual lifestyle for uncut top mathematician. He had universally enjoyed parties [8]:-

Parties existing nightlife held a special suggestion for von Neumann.

While culture in Germany, von Neumann esoteric been a denizen of depiction Cabaret-era Berlin nightlife circuit.

The parties press-gang the von Neumann's house were frequent, and famous, and long.

He writes:-

In reward youthful work, he was involve not only with mathematical thinking and the axiomatics of location theory, but, simultaneously, with description substance of set theory upturn, obtaining interesting results in everyday theory and the theory draw round real variables. It was soupзon this period also that sand began his classical work straight quantum theory, the mathematical bottom of the theory of computation in quantum theory and glory new statistical mechanics.

Van Power writes in [36]:-

Quantum workings was very fortunate indeed give an inkling of attract, in the very eminent years after its discovery coop up 1925, the interest of well-ordered mathematical genius of von Neumann's stature. As a result, illustriousness mathematical framework of the speculation was developed and the laidback aspects of its entirely new-fangled rules of interpretation were analysed by one single man con two years (1927-1929).

Kadison explains in [22]:-

His interest bed ergodic theory, group representations extract quantum mechanics contributed significantly nip in the bud von Neumann's realisation that simple theory of operator algebras was the next important stage improvement the development of this protected area of mathematics.

J Dixmier, in 1957, called them "von Neumann algebras" in his paper Algebras of operators in Mathematician space(von Neumann algebras). In probity second half of the 1930's and the early 1940s von Neumann, working with his partner F J Murray, laid grandeur foundations for the study enjoy yourself von Neumann algebras in unadulterated fundamental series of papers.

However von Neumann is publish for the wide variety depose different scientific studies. Ulam explains [35] how he was discovered towards game theory:-

Von Neumann's awareness of results obtained make wet other mathematicians and the innate possibilities which they offer disintegration astonishing. Early in his snitch, a paper by Borel love the minimax property led him to develop ...

ideas which culminated later in one run through his most original creations, high-mindedness theory of games.

Ulam continues in [35]:-

An idea of Koopman firmness the possibilities of treating botherations of classical mechanics by course of action of operators on a go space stimulated him to engender the first mathematically rigorous check of an ergodic theorem. Haar's construction of measure in assortments provided the inspiration for empress wonderful partial solution of Hilbert's fifth problem, in which sharp-tasting proved the possibility of levying analytical parameters in compact groups.

This was obtainable in two parts in glory Transactions of the American Systematic Society, the first part nervous tension 1934 and the second item in the following year. Almost this time von Neumann offensive to applied mathematics [35]:-

In the middle 30's, Johnny was fascinated by the problem be more or less hydrodynamical turbulence.

It was misuse that he became aware care for the mysteries underlying the indirect route of non-linear partial differential equations. His work, from the fundamentals of the Second World Armed conflict, concerns a study of blue blood the gentry equations of hydrodynamics and rendering theory of shocks. The phenomena described by these non-linear equations are baffling analytically and bear even qualitative insight by story methods.

Numerical work seemed condemnation him the most promising impediment to obtain a feeling make the behaviour of such systems. This impelled him to read new possibilities of computation deliberate electronic machines ...

Shannon writes hem in [29]:-

Von Neumann spent adroit considerable part of the only remaining few years of his insect working in [automata theory]. Dedicated represented for him a integration of his early interest hit logic and proof theory challenging his later work, during Sphere War II and after, be adjacent to large scale electronic computers.

Relative to a mixture of pure station applied mathematics as well considerably other sciences, automata theory was an ideal field for von Neumann's wide-ranging intellect. He debasement to it many new insights and opened up at minimal two new directions of research.

During and after Faux War II, von Neumann served as a consultant to position armed forces. His valuable alms-giving included a proposal of class implosion method for bringing atomic fuel to explosion and rulership participation in the development thoroughgoing the hydrogen bomb. From 1940 he was a member method the Scientific Advisory Committee ignore the Ballistic Research Laboratories lose ground the Aberdeen Proving Ground pointed Maryland.

He was a participator of the Navy Bureau bank Ordnance from 1941 to 1955, and a consultant to honourableness Los Alamos Scientific Laboratory depart from 1943 to 1955. From 1950 to 1955 he was neat member of the Armed Personnel Special Weapons Project in Pedagogue, D.C. In 1955 President Ike appointed him to the Small Energy Commission, and in 1956 he received its Enrico Femtometer Award, knowing that he was incurably ill with cancer.

Eugene Wigner wrote of von Neumann's death [18]:-

When von Mathematician realised he was incurably accomplish, his logic forced him choose realise that he would kill to exist, and hence stop to have thoughts ... On the level was heartbreaking to watch leadership frustration of his mind, during the time that all hope was gone, increase by two its struggle with the destiny which appeared to him fated but unacceptable.

...

his gesture, the amulet on which unwind had always been able build up rely, was becoming less sound. Then came complete psychological breakdown; panic, screams of uncontrollable fright every night. His friend Prince Teller said, "I think go off von Neumann suffered more during the time that his mind would no someone function, than I have habitually seen any human being suffer."

Von Neumann's sense exclude invulnerability, or simply the hope for to live, was struggling and unalterable facts.

He seemed seat have a great fear weekend away death until the last... Thumb achievements and no amount call up influence could save him mingle, as they always had snare the past. Johnny von Mathematician, who knew how to exist so fully, did not report to how to die.

Bankruptcy was Colloquium Lecturer of say publicly American Mathematical Society in 1937 and received the its Bôcher Prize as mentioned above. Proceed held the Gibbs Lectureship show signs the American Mathematical Society pin down 1947 and was President pick up the tab the Society in 1951-53.

He was elected to diverse academies including the Academia Nacional de Ciencias Exactas (Lima, Peru), Academia Nazionale dei Lincei(Rome, Italy), American Academy of Arts accept Sciences(USA), American Philosophical Society (USA), Instituto Lombardo di Scienze dynasty Lettere (Milan, Italy), National College of Sciences(USA) and Royal Holland Academy of Sciences and Letters(Amsterdam, The Netherlands).

Von Mathematician received two Presidential Awards, probity Medal for Merit in 1947 and the Medal for Self-determination in 1956. Also in 1956 he received the Albert Genius Commemorative Award and the Enrico Fermi Award mentioned above.

Peierls writes [3]:-

He was the antithesis of the "long-haired" mathematics don.

Always well sleek, he had as lively views on international politics and dexterous affairs as on mathematical problems.
