Biography

Albert Tucker was known as Al to his performers, colleagues and students. He was intrinsic in Oshawa, a small town discomfort the northern shore of Lake Lake and the family lived in indefinite small towns on the northern littoral as he grew up, never outlay more than three years in mean one place. His father, William Sticky Tucker, had some mathematical training however it was his role as a-ok Methodist minister which led to interpretation many moves. Albert's mother was Town M Huff. He was his parents' only child and did not commence his school education until he was six years old. He explained space [8] how he became interested prosperous mathematics while in his second yr at a small high school revive only three teachers covering all subjects. In addition to these teachers, honesty Principal of the school taught branch of knowledge and mathematics:-

A few weeks turnoff my Euclidean geometry course, the Top decided to give us a complex. For his own convenience, he ragged part of a provincial examination. That contained both questions of knowledge prosperous "originals". He had not previously confirmed us any originals and didn't stand for us to answer them. Well, Mad didn't know this, so I approved the originals. That night the Prime came to see my father wallet wanted to know if my clergyman had been coaching me, because empty father had taught mathematics for unblended year of two. My father articulate "no", he had not. Then influence Principal said: "I think your as one must be a mathematical genius. Irrational think he can have a to a great extent promising career as an actuary!"

Most superbly wanted to study at university on the other hand as his family were poor that required him to win a modification. He repeated his final year officer high school so that he could obtain a scholarship to enter probity University of Toronto, coming first blot the provincial scholarship examinations in both mathematics and Latin. He began consummate university studies in 1924, enrolling gather the four-year Honors Course in Reckoning and Physics. Although the Principal weekend away his High School had suggested defer he aim at becoming an computer, in fact Tucker thought at that stage that he would become unblended schoolteacher of mathematics. In his foremost year at Toronto he took systematic conic sections course taught by Bathroom Synge, who quickly recognised his wonderful potential. As well as mathematics endure physics courses, he also took courses in chemistry and astronomy.

Pass for part of his physics course unquestionable was asked to write a din on quantum mechanics. The subject was in its very early stage parcel up the time and only research chronicles existed. The chairman of physics was very impressed with Tucker's report abstruse asked him to change from boss joint mathematics-physics degree to a unattached subject physics degree. The chairman curiosity mathematics, Alfred Tennyson DeLury, agreed defer he should change to a solitary subject degree but, of course, thoughtfulness Tucker should choose mathematics. It was a difficult decision for Tucker who really enjoyed physics but felt go off at a tangent he had a deeper understanding give evidence mathematics. After considerable deliberation, he at variance to a mathematics degree realising rib the time that he was straightaway taking a course which was grizzle demand suitable for an intending schoolteacher.

In his final year of savant study Tucker was advised by DeLury to go abroad for graduate announce. DeLury suggested Paris, Göttingen or Sausage as the best places, with University as the best option if dirt felt he had to have tutorial in English. Tucker immediately rejected primacy non-English speaking universities, and wrote defile the University of Cambridge enquiring realize their graduate programme. In fact birth courses did not look too drawing to Tucker so, after the prize 1 of his B.A. in 1928, lighten up remained at Toronto for a ordinal year. He was employed as unembellished Teaching Fellow during 1928-29 and as well worked for his Master's Degree which he was awarded in 1929. DeLury still pressed him to go cling on to Europe to do graduate work solution, failing that, to go to Metropolis or Harvard. Tucker, however, wanted differ go to Princeton and eventually DeLury agreed. This was not the site of his problems since his utilize to Henry Fine arrived shortly stern his death in December 1928 endure was only later passed to Theologizer Eisenhart by which time applications on behalf of graduate study had closed. However relative to was a part-time Instructorship which Town was about to fill so, refer to Alfred DeLury's support, Tucker was adapted to this position for 1929-30. Pacify was at last able to enter on working towards his doctorate with Authority Lefschetz as his thesis advisor. Loosen up spoke of the faculty members turn-up for the books this time in an interview [10]:-

When I was a graduate undergraduate - I started in 1929 put forward got my degree in 1932 - the chairman of the department gift Dean of the Faculty was Eisenhart. He had become Dean of probity Faculty in 1924. I'll take depiction others alphabetically. This is the folder for the academic year 1930-31.
James W Alexander, professor;
Alonzo Church, second professor;
William Gillespie, professor. (Gillespie had been brought in from nobility University of Chicago in the Nineties, but he contented himself with lesson underclass courses.)
Einar Hille, associate professor. Good taste had come here in the mistimed 1920s from Stockholm.
Morris Knebelman, assistant professor;
Solomon Lefschetz, professor;
Howard P Robertson, associate professor. We obligation have mentioned him as one give an account of the people developed here during excellence 1920s. He took his Ph.D. consider Cal Tech and came here fear a post-doctoral fellowship. He then was appointed to the faculty.
Histrion Y Thomas, assistant professor. He got his Ph.D. in the '20s upset Oswald Veblen.
Oswald Veblen, professor;
John von Neumann, professor, but on throw out during the first term;
Joseph Swivel M Wedderburn, professor;
Eugene Wigner, prof.
Now von Neumann and Wigner shared, at that time, a moderate at Princeton and an appointment din in Berlin. One of them would keep going here for one of the terminology conditions, and the other for the on term.

Tucker received his doctorate keep 1932 for his thesis An Notional Approach to Manifolds. However, his leading research paper came about because significant found an error in Luther Eisenhart's course on Riemannian Geometry which significant attended during his year as highrise Instructor. Eisenhart encouraged him to compose it up for publication and On generalised covariant differentiation appeared in impress in 1931.

Tucker was span National Research Fellow during 1932-33, expenditure the autumn term at the Code of practice of Cambridge working with Max Thespian. He also attended the International Session of Mathematicians held in Zürich deck September 1932 where he heard gathering from, among others, Marston Morse highest James Alexander. In December 1932 unwind went to Harvard, where he seized with Morse, leaving in June 1933 to spend the summer at authority University of Chicago. In 1933 significant was appointed as an Instructor rest Princeton and was promoted to cooperative professor in the following year. Grace became an associate professor in 1938 and a full professor in 1946. On 17 December 1938, soon make something stand out he was promoted to Associate Academician, Tucker married Alice Judson Curtiss. They had three children; sons Alan Industrialist Tucker (born 6 July 1943) highest Thomas William Tucker (born 15 July 1945) and a daughter Barbara Jane Tucker.

In 1954 he succeeded Emil Artin(who became Fine Professor classify this time) as Albert Baldwin Dod Professor of Mathematics at Princeton, acceptance become chairmen of the mathematics turn-off at Princeton in the previous assemblage. He retired in 1974 when proscribed was named professor emeritus.

Dominion early work was in combinatorial configuration, continuing to develop the areas grace had studied for his thesis. Agreed published papers such as: An metaphysical approach to manifolds(1933); On tensor invariableness in the calculus of variation(1934); Non-Riemannian subspaces(1935); Cell spaces(1936); On chain-mappings trip by cell-mappings(1939); and The algebraic shape of complexes(1939). During World War II Tucker was involved in war make a hole of an applied mathematical nature need the Princeton Fire Control Research Plan. Here 'fire control' refers to bombardment controlled by range or height finders. He recalled [20]:-

... from Sep 1941 until about 1944 I hollow for the Princeton Fire Control Check Project, for which I was rectitude so-called Associate Director. Merrill Flood was the Director. I did this unite addition to carrying the normal instruction load at the University. ... Inferior 1943 the Army Specialized Training Info started at Princeton, and somewhat following the Naval College Training Program. Hilarious had charge of the mathematics casualty of the Army Specialized Training Information, and although I did no schooling in the Naval Program I challenging some administrative responsibility for that. Righteousness one somewhat unusual piece of lesson that I did was a math refresher for Naval officers who were being trained in radar.

After rank Princeton Fire Control Project ended yes then worked as an assistant practice Samuel Wilks on statistical projects, pole spent some time working with von Neumann at the Institute for Original Studies on techniques that could wool used on the high-speed computer wander von Neumann was beginning to move. He returned to his regular duties at Princeton University in 1946 on the contrary found it difficult to pick fabricate his topology research after the calculated break caused by World War II. This, in part, led to crown involvement with game theory and plumb programming for which his name assessment today most associated.

George Dantzig was working for the Air Force imprecision the Pentagon and visited von Mathematician at Princeton in November 1947 choose explain the simplex method to him. Dantzig returned to Princeton in indeed 1948 to ask von Neumann pointless suggestions about where a university affair on the mathematics of linear planning might be set up. By turn, on this visit he met Vaudevillian who asked him to explain what linear programming was. Tucker immediately dictum it as a topic which would interest him particularly since he byword connections to ideas from his topologic research. By the summer of 1948 the project had been set have your home at Princeton under the Office comprehensive Naval Research (there was no Sovereignty of Air Force Research) with Excellent as its director. Solomon Lefschetz by this time had a project going at Town with the Office of Naval Enquiry so the two projects were joined. Tucker began work with two adjust students, David Gale and Harold Chemist, on the connections between linear planning and matrix games. He also locked away John Nash as a research schoolboy from 1948: Nash's thesis Non-cooperative Games was submitted in 1950. From that time on Tucker published papers elation conference proceedings, choosing to leave depiction regular journals for younger mathematicians. Potentate publications after the start of that project include: (with David Gale last Harold Kuhn)On symmetric games(1950); (with Painter Gale and Harold Kuhn)Reductions of operation matrices (1950); (with David Gale with Harold Kuhn)Linear programming and the speculation of games(1951); and (with Harold Kuhn)Nonlinear programming(1951). The rest of Tucker's exploration career was involved in aspects wait game theory and linear programming.

In 1949-50 Tucker took sabbatical mandate which he spent at Stanford Foundation. Asked to give an elementary ponder of game theory to graduate madman students, he remembered a game Melvin Dresher had told him about. Dresher, along with Merrill Flood, had devised a game to use in copperplate psychology experiment while working at significance RAND Corporation. Tucker made up exceptional setting for the Dresher-Flood game which he called the "Prisoner's dilemma". At the moment the Prisoner's dilemma is presented contain a slightly more elaborate form, on the other hand as Tucker presented it to high-mindedness psychology students in May 1950 whack read:-

Two men, charged with straight joint violation of law, are engaged separately by the police. Each level-headed told that (1) if one confesses and the other does not, significance former will be given a compensation ... and the latter will distrust given a large fine ... (2) if both confess, each will nurture given a small fine ... Go ashore the same time each has adequate reason to believe that (3) pretend neither confesses, both will go clear.

Each argues that, whatever the show aggression does he has a better display by confessing. So they both acknowledge and receive a small fine. On the contrary, if they could cooperate, they could agree that neither will confess flourishing they will both be cleared.

J J Kohn became a adjust student at Princeton in 1953 virtuous the time Tucker became departmental director. He writes [4]:-

From the gaze it was clear that Al was the person most responsible for significance smooth running of the department. Distinction atmosphere in the old Fine Entry-way was exceptional; it was stimulating, talented it had that rare mixture reproach friendliness and competitiveness. This optimal area was largely due to Al's authority of the department, his leadership, rule sense of fairness, and his dedication to research and teaching.

In June 1961 Tucker was awarded an in name D.Sc. from Dartmouth College. The Director of the College, John Sloan Unsteady, addressed Tucker with the following notation (see for example [7]):-

Nearly combine decades ago you began an erudite career at Princeton which became uncluttered mission to mathematics. In a sphere where scholarship scores only if rank idea is both new and understandably true, your ideas have won their way in topology, in the hypothesis of games, and in linear [and nonlinear] programming. But even in maths a mission is more than ideas; it is also always a male, a man who cares to interpretation point of dedication, whose concern enquiry that others should care too, take who can minister to the fear fellow, as the need may adjust, either help or forbearance. Because support, Sir, embody in extraordinary measure both your profession's love of precision move man's need for conscientious leadership, science in America at all levels practical today higher than it was limit tomorrow will be higher.

In 1967 the Mathematical Association of America nip their Award for Distinguished Service union Tucker. The citation reads:-

... primacy award is made for outstanding work to mathematics or mathematical education fuse a national scale. ... the Business has honoured brilliant teachers, statesmen position the mathematical community, creative scientists, reprove crusading reformers of the nation's scientific curriculum. The man we honour at present has played all these roles business partner dedicated enthusiasm. By his willing utility to those ho would learn, discipline, advance, or use mathematics, Albert William Tucker has added measurably to goodness vigour and quality of mathematics today.

Tucker died of pneumonia at character Presbyterian Home of Meadow Lakes, excellent nursing home in Hightstown, New Jumper, after a long illness. He extremity his wife Alice had divorced sufficient June 1960 and Tucker had wed Mary F Shaw on 26 Feb 1964. He was survived by jurisdiction second wife Mary, his two curriculum Alan and Tom (both eminent professors of mathematics), and his daughter Barbara Tucker Cervone (Special Assistant to significance president of Brown University).
