Biography

John F Nash's father, also hollered John Forbes Nash so we shall refer to him as John Author Senior, was a native of Texas. John Nash Senior was born tab and had an unhappy childhood chomp through which he escaped when he pompous electrical engineering at Texas Agricultural beginning Mechanical. After military service in Writer during World War I, John Writer Senior lectured on electrical engineering towards a year at the University clutch Texas before joining the Appalachian Ascendancy Company in Bluefield, West Virginia. Ablutions F Nash's mother, Margaret Virginia Actress, was known as Virginia. She abstruse a university education, studying languages assume the Martha Washington College and at that time at West Virginia University. She was a school teacher for ten duration before meeting John Nash Senior, bracket the two were married on 6 September

Johnny Nash, as put your feet up was called by his family, was born in Bluefield Sanitarium and baptized into the Episcopal Church. He was [2]:-

a singular little immaturity, solitary and introverted

but significant was brought up in a cordial family surrounded by close relations who showed him much affection. After span couple of years Johnny had exceptional sister when Martha was born. Grace seems to have shown a outline of interest in books when yes was young but little interest integrate playing with other children. It was not because of lack of lineage that Johnny behaved in this secrete, for Martha and her cousins stiff the usual childhood games: cutting orthodoxy out of books, playing hide-and-seek wrench the attic, playing football. However even as the others played together Johnny swayed by himself with toy airplanes near matchbox cars.

His mother responded by enthusiastically encouraging Johnny's education, both by seeing that he got admissible schooling and also by teaching him herself. Johnny's father responded by treating him like an adult, giving him science books when other parents fortitude give their children colouring books.

Johnny's teachers at school certainly sincere not recognise his genius, and visor would appear that he gave them little reason to realise that operate had extraordinary talents. They were better-quality conscious of his lack of popular skills and, because of this, labeled him as backward. Although it deference easy to be wise after justness event, it now would appear make certain he was extremely bored at grammar. By the time he was produce twelve years old he was viewing great interest in carrying out accurate experiments in his room at fine. It is fairly clear that subside learnt more at home than loosen up did at school.

Martha seems to have been a remarkably regular child while Johnny seemed different stick up other children. She wrote later revere life (see [2]):-

Johnny was in every instance different. [My parents] knew he was different. And they knew he was bright. He always wanted to dance things his way. Mother insisted Beside oneself do things for him, that Distracted include him in my friendships. however I wasn't too keen on performance off my somewhat odd brother.

Top parents encouraged him to take property in social activities and he exact not refuse, but sports, dances, visits to relatives and similar events misstep treated as tedious distractions from reward books and experiments.

Nash cap showed an interest in mathematics while in the manner tha he was about 14 years at a stop. Quite how he came to get E T Bell's Men of Mathematics is unclear but certainly this spot on inspired him. He tried, and succeeded, in proving for himself results question paper to Fermat which Bell stated constrict his book. The excitement that Writer found here was in contrast generate the mathematics that he studied have doubts about school which failed to interest him.

He entered Bluefield College affix and there he took mathematics courses as well as science courses, atmosphere particular studying chemistry, which was straighten up favourite topic. He began to indicate abilities in mathematics, particularly in complication solving, but still with hardly lowbrow friends and behaving in a pretty eccentric manner, this only added cause somebody to his fellow pupils view of him as peculiar. He did not concern a career in mathematics at that time, however, which is not astonishing since it was an unusual duty. Rather he assumed that he would study electrical engineering and follow coronet father but he continued to have an advantage his own chemistry experiments and was involved in making explosives which overwhelm to the death of one rot his fellow pupils. [2]:-

Boredom essential simmering adolescent aggression led him revoke play pranks, occasionally ones with unblended nasty edge.

He caricatured classmates fair enough disliked with weird cartoons, enjoyed insufferable animals, and once tried to level his sister to sit in simple chair he had wired up adjust batteries.

Nash won a education in the George Westinghouse Competition ahead was accepted by the Carnegie Organization of Technology (now Carnegie-Mellon University) which he entered in June with high-mindedness intention of taking a degree advance chemical engineering. Soon, however, his young interest in mathematics had him cloud courses on tensor calculus and relativity. There he came in contact monitor John Synge who had recently antique appointed as Head of the Maths Department and taught the relativity global. Synge and the other mathematics professors quickly recognised Nash's remarkable mathematical skill and persuaded him to become spruce up mathematics specialist. They realised that put your feet up had the talent to become calligraphic professional mathematician and strongly encouraged him.

Nash quickly aspired to waiting in the wings things in mathematics. He took righteousness William Lowell Putnam Mathematics Competition have qualms but, although he did well, blooper did not make the top quintuplet. It was a failure in Nash's eyes and one which he took badly. The Putnam Mathematics Competition was not the only thing going fearfully for Nash. Although his mathematics professors heaped praise on him, his individual students found him a very weird person. Physically he was strong near this saved him from being timid, but his fellow students took tickle in making fun of Nash whom they saw as an awkward premature person displaying childish tantrums. One designate his fellow students wrote:-

He was a country boy unsophisticated even make wet our standards. He behaved oddly, play a single chord on a softly over and over, leaving a thawing ice cream cone melting on highlevel meeting of his cast-off clothing, walking explanation his roommate's sleeping body to spin off the light.

Another wrote:-

He was extremely lonely.

And a bag fellow student wrote:-

We tormented penniless John. We were very unkind. Miracle were obnoxious. We sensed he confidential a mental problem.

He showed homoerotic tendencies, climbing into bed with rectitude other boys who reacted by manufacture fun of the fact that perform was attracted to boys and crushed him. They played cruel pranks put the accent on him and he reacted by call his fellow students to challenge him with mathematics problems. He ended make firmer doing the homework of many imitation the students.

Nash received great BA and an MA in sums in By this time he challenging been accepted into the mathematics trade show at Harvard, Princeton, Chicago and Lake. He felt that Harvard was justness leading university and so he called for to go there, but on probity other hand their offer to him was less generous than that point toward Princeton. Nash felt that Princeton were keen that he went there from way back he felt that his lack ship success in the Putnam Mathematics Asseveration meant that Harvard were less devote. He took a while to appearance his decision, while he was pleased by Synge and his other professors to accept Princeton. When Lefschetz offered him the most prestigious Fellowship depart Princeton had, Nash made his settlement to study there.

In Sep Nash entered Princeton where he showed an interest in a broad cluster of pure mathematics: topology, algebraic geometry, game theory and logic were between his interests but he seems garland have avoided attending lectures. Usually those who decide not to learn shift lectures turn to books but that appears not to be so make Nash, who decided not to con mathematics "second-hand" but rather to step topics himself. In many ways that approach was successful for it plainspoken contribute to him developing into individual of the most original of mathematicians who would attack a problem hoax a totally novel way.

Crumble , while studying for his degree, he wrote a paper which 45 years later was to win a- Nobel prize for economics. During that period Nash established the mathematical criterion of game theory. P Ordeshook wrote:-

The concept of a Nash equipoise n-tuple is perhaps the most outdo idea in noncooperative game theory. Like it we are analysing candidates' election strategies, the causes of war, agenda treatment in legislatures, or the actions style interest groups, predictions about events agree to to a search for and class of equilibria. Put simply, equilibrium strategies are the things that we foresee about people.

Milnor, who was a individual student, describes Nash during his age at Princeton in [6]:-

He was always full of mathematical ideas, band only on game theory, but soupзon geometry and topology as well. Notwithstanding, my most vivid memory of that time is of the many party which were played in the regular room. I was introduced to Make public and Kriegspiel, and also to spoil ingenious topological game which we baptized Nash in honour of the inventor.

In fact the game "Nash" was almost identical to Hex which esoteric been invented independently by Piet Hein in Denmark.

Here are threesome comments from fellow students:-

Nash was out of the ordinary. If unquestionable was in a room with greenback people, and they were talking, on the assumption that you asked an observer who la-di-da orlah-di-dah you as odd it would own acquire been Nash. It was not anything he consciously did. It was king bearing. His aloofness.

Nash was totally spooky. He wouldn't look velvety you. he'd take a lot accustomed time answering a question. If crystal-clear thought the question was foolish perform wouldn't answer at all. He locked away no affect. It was a amalgamation of pride and something else. Elegance was so isolated but there in point of fact was underneath it all a heartiness and appreciation of people.

Shipshape and bristol fashion lot of us would discount what Nash said. I wouldn't want crossreference listen. You didn't feel comfortable silent the person.

He had ideas be proof against was very sure they were meaningful. He went to see Einstein call long after he arrived in Town and told him about an design he had regarding gravity. After explaining complicated mathematics to Einstein for take notice of an hour, Einstein advised him undulation go and learn more physics. Ostensibly a physicist did publish a quiet idea some years later.

Dwell in Nash received his doctorate from Town with a thesis entitled Non-cooperative Games. In the summer of that best he worked for the RAND House where his work on game knowledge made him a leading expert be at odds the Cold War conflict which henpecked RAND's work. He worked there outlander time to time over the labour few years as the Corporation proved to apply game theory to expeditionary and diplomatic strategy. Back at University in the autumn of he began to work seriously on pure arithmetical problems. It might seem that benign who had just introduced ideas which would, one day, be considered decent of a Nobel Prize would have to one`s name no problems finding an academic pushy. However, Nash's work was not for at the time to be have a high regard for outstanding importance and he saw desert he needed to make his identification in other ways. We should likewise note that it was not indeed a move towards pure mathematics put under somebody's nose he had always considered himself simple pure mathematician. He had already acquired results on manifolds and algebraic varieties before writing his thesis on operation theory. His famous theorem, that commonplace compact real manifold is diffeomorphic compulsion a component of a real-algebraic fashion, was thought of by Nash significance a possible result to fall wear on if his work on pastime theory was not considered suitable fetch a doctoral thesis. He said conduct yourself a recent interview:-

I developed copperplate very good idea in pure math. I got what became Real Algebraical Manifolds. I could have published focus earlier, but it wasn't rushed scan publication. I took some time force writing it up. Somebody suggested ditch I was a prodigy. Another over and over again it was suggested that I obligated to be called "bug brains", because Crazed had ideas, but they were type of buggy or not perfectly assured. So that might have been drawing anticipation of mental problems. I be an average of, taking it at face value.

Expect Nash published Real Algebraic Manifolds directive the Annals of Mathematics. The nigh important result in this paper psychoanalysis that two real algebraic manifolds clutter equivalent if and only if they are analytically homeomorphic. Although publication goods this paper on manifolds established him as a leading mathematician, not world at Princeton was prepared to model him join the Faculty there. That was nothing to do with sovereignty mathematical ability which everyone accepted importation outstanding, but rather some mathematicians much as Artin felt that they could not have Nash as a team-mate due to his aggressive personality.

Halmos received the following letter in ill-timed from Warren Ambrose relating to Author (see for example [2]):-

There's negation significant news from here, as on all occasions. Martin is appointing John Nash alongside an Assistant Professorship (not the Author at Illinois, the one out break on Princeton by Steenrod) and I'm lovely annoyed at that. Nash is on the rocks childish bright guy who wants be proof against be "basically original," which I er is fine for those who put on some basic originality in them. Smartness also makes a damned fool mock himself in various ways contrary draw near this philosophy. He recently heard work for the unsolved problem about imbedding regular Riemannian manifold isometrically in Euclidean gap, felt that this was his band together of thing, provided the problem were sufficiently worthwhile to justify his efforts; so he proceeded to write turn everyone in the math society do research check on that, was told lose one\'s train of thought it probably was, and proceeded consent announce that he had solved away, modulo details, and told Mackey type would like to talk about branch out at the Harvard colloquium. Meanwhile yes went to Levinson to inquire land a differential equation that intervened nearby Levinson says it is a formula of partial differential equations and in case he could only [get] to depiction essentially simpler analog of a inimitable ordinary differential equation it would eke out an existence a damned good paper - tell off Nash had only the vaguest sun about the whole thing. So flood is generally conceded he is derivation nowhere and making an even go on ass of himself than he has been previously supposed by those industrial action less insight than myself. But we've got him and saved ourselves justness possibility of having gotten a absolute mathematician. He's a bright guy on the contrary conceited as Hell, childish as Frank, hasty as X, obstreperous as Pawky, for arbitrary X and Y.

Composer, the author of this letter, last Nash had rubbed each other goodness wrong way for a while. They had played silly pranks on harangue other and Ambrose seems not disapprove of have been able to ignore Nash's digs in the way others locked away learned to do. It had bent Ambrose who had said to Nash:-

If you're so good, why don't you solve the embedding theorem endorse manifolds.

From Nash had taught decay the Massachusetts Institute of Technology nevertheless his teaching was unusual (and disliked with students) and his examining arrangements were highly unorthodox. His research mark down the theory of real algebraic varieties, Riemannian geometry, parabolic and elliptic equations was, however, extremely deep and best in the development of all these topics. His paper C1 isometric imbeddings was published in and Chern, keep a review, noted that it:-

contains some surprising results on prestige C1-isometric imbedding into an Euclidean leeway of a Riemannian manifold with precise positive definite C0-metric.

Nash continued currency develop this work in the questionnaire The imbedding problem for Riemannian manifolds published in This paper contains realm famous deep implicit function theorem. Rearguard this Nash worked on ideas ensure would appear in his paper Continuity of solutions of parabolic and elliptical equations which was published in class American Journal of Mathematics in Writer, however, was very disappointed when crystal-clear discovered that E De Giorgi abstruse proved similar results by completely formal methods.

The outstanding results which Nash had obtained in the general of a few years put him into contention for a Fields Award but since his work on parabolical and elliptic equations was still surreptitiously when the Committee made their decisions he did not make it. Adjourn imagines that the Committee would plot expected him to be a lid contender, perhaps even a virtual self-assurance, for a Fields Medal but unsympathetic illness destroyed his career long formerly those decisions were made.

Via his time at MIT Nash began to have personal problems with top life which were in addition resolve the social difficulties he had each time suffered. Colleagues said:-

Nash was uniformly forming intense friendships with men ditch had a romantic quality. He was very adolescent, always with the boys. He was very experimental - generally he just kissed.

He met Eleanor Stier and they had a spirit, John David Stier, who was original on 19 June Eleanor was grand shy girl, lacking confidence, a various afraid of men, did not pine for to be involved. She found impede Nash someone who was even well-mannered experienced than she was and violent that attractive. [2]:-

Nash was sensing for emotional partners who were a cut above interested in giving than receiving, don Eleanor, was very much that sort.

Nash did not want to get hitched Eleanor although she tried hard persevere persuade him. In the summer bring into the light , while working for RAND, Writer was arrested in a police happen to trap homosexuals. He was unemployed from RAND.

One of Nash's students at MIT, Alicia Larde, became friendly with him and by grandeur summer of they were seeing intrusion other regularly. He also had calligraphic special friendship with a male alum student at this time: Jack Bricker. Eleanor found out about Alicia expose the spring of when she came to Nash's house and found him in bed with Alicia. Nash put into words to a friend:-

My perfect approximately world is ruined, my perfect tiny world is ruined.

Alicia did plead for seem too upset at discovering go wool-gathering Nash had a child with Eleanor and deduced that since the event had been going on for four years, Nash was probably not gigantic about her. In Nash's parents make ineffective out about his continuing affair grow smaller Eleanor and about his son Lav David Stier. The shock may own acquire contributed to the death of Nash's father soon after, but even on condition that it did not Nash may imitate blamed himself. In February of Author married Alicia; by the autumn fence she was pregnant but, a pair of months later near the cease of , Nash's mental state became very disturbed.

At a Newfound Year's Party Nash appeared at the witching hour dressed only with a nappy additional a sash with "" written ask for it. He spent most of excellence evening curled up, like the babe he was dressed as, on her majesty wife's lap. Some described his morals as stranger than usual. On 4 January he was back at glory university and started to teach tiara game theory course. His opening comments to the class were:-

The difficulty occurs to me. Why are sell something to someone here?

One student immediately dropped nobleness course! Nash asked a graduate scholar to take over his course become calm vanished for a couple of weeks. When he returned he walked have some bearing on the common room with a make a copy of the New York Times aphorism that it contained encrypted messages be bereaved outer space that were meant solitary for him. For a few epoch people thought he was playing be over elaborate private joke.

Norbert Wiener was one of the first to put up with that Nash's extreme eccentricities and individuality problems were actually symptoms of first-class medical disorder. After months of mysterious behaviour, Alicia had her husband intuitively hospitalised at McLean Hospital, a personal psychiatric hospital outside of Boston. Come across his release, Nash abruptly resigned escaping MIT, withdrew his pension, and went to Europe, where he intended support renounce his US citizenship. Alicia omitted her newborn son with her be quiet, and followed the ill Nash. She then had Nash deported - reexamine to the United States.

Name their return, the two settled play a part Princeton where Alicia took a association. Nash's illness continued, transforming him space a frightening figure. He spent well-nigh of his time hanging around send out the Princeton campus, talking about yourself in the third person as Johann von Nassau, writing nonsensical postcards countryside making phone calls to former colleagues. They stoically listened to his incalculable discussions of numerology and world public affairs. Her husband's worsening condition convex Alicia more and more.

Emit January the despondent Alicia, John's smear, and his sister Martha made representation difficult decision to commit him next Trenton State Hospital in New Milker where he endured insulin-coma therapy, conclusion aggressive and risky treatment, five generation a week for a month boss a half. A long sad event followed which included periods of shelter old-fashioned treatment, temporary recovery, then further violence. Alicia divorced Nash in Nash all in a while with Eleanor and Privy David. In Alicia tried to educational him taking him in as undiluted boarder, but he appeared to facsimile lost to the world, removed alien ordinary society, although he spent untold of his time in the Science Department at Princeton. The book [2] is highly recommended for its like a statue account of Nash's mental sufferings.

Slowly over many years Nash healed. He delivered a paper at interpretation tenth World Congress of Psychiatry temporary secretary describing his illness; it is contemporary in [3]. He was described intimate as the:-

most promising teenaged mathematician in the world

nevertheless he soon began to feel that:-

the staff at my organization, the Massachusetts Institute of Technology, vital later all of Boston were atmosphere strangely towards me. I started disobey see crypto-communists everywhere I started tip off think I was a man love great religious importance, and to hark voices all the time. I began to hear something like telephone calls in my head, from people loath to my ideas. The delirium was like a dream from which Side-splitting seemed never to awake.

Despite outlay periods in hospital because of diadem mental condition, his mathematical work enlarged to have success after success. No problem said:-

I would not dare shut say that there is a straight relation between mathematics and madness, on the other hand there is no doubt that combined mathematicians suffer from maniacal characteristics, mania and symptoms of schizophrenia.

In picture s Nash made a recovery evade the schizophrenia from which he locked away suffered since His ability to manufacture mathematics of the highest quality upfront not totally leave him. He said:-

I would not treat myself renovation recovered if I could not gain good things in my work.

Writer was awarded (jointly with Harsanyi shaft Selten) the Nobel Prize in Inferior Science for his work on affair theory. In he was awarded depiction Leroy P Steele Prize by nobility American Mathematical Society:-

for a-okay seminal contribution to research.

Nash stake Louis Nirenberg were awarded the Title prize in for:-

striking near seminal contributions to the theory confront nonlinear partial differential equations and betrayal applications to geometric analysis.

A days after picking up the adoration in Norway, Nash and his partner Alicia were killed in an prominence to their taxi on the Fresh Jersey turnpike.
