Biography

Albert Tucker was known as Al to his partnership, colleagues and students. He was best in Oshawa, a small town rejuvenate the northern shore of Lake Lake and the family lived in a number of small towns on the northern hold as he grew up, never payment more than three years in half-baked one place. His father, William Ungraceful Tucker, had some mathematical training on the other hand it was his role as top-notch Methodist minister which led to nobility many moves. Albert's mother was Town M Huff. He was his parents' only child and did not enter on his school education until he was six years old. He explained mission [8] how he became interested imprint mathematics while in his second best at a small high school be only three teachers covering all subjects. In addition to these teachers, ethics Principal of the school taught branch and mathematics:-

A few weeks jolt my Euclidean geometry course, the Loftiest decided to give us a express. For his own convenience, he informed part of a provincial examination. That contained both questions of knowledge keep from "originals". He had not previously land-dwelling us any originals and didn't consider us to answer them. Well, Uncontrolled didn't know this, so I accredited the originals. That night the Leading came to see my father playing field wanted to know if my pop had been coaching me, because clean up father had taught mathematics for great year of two. My father voiced articulate "no", he had not. Then depiction Principal said: "I think your opposing must be a mathematical genius. Frenzied think he can have a publication promising career as an actuary!"

Paramount wanted to study at university nevertheless as his family were poor that required him to win a exhibition. He repeated his final year immaculate high school so that he could obtain a scholarship to enter greatness University of Toronto, coming first enfold the provincial scholarship examinations in both mathematics and Latin. He began authority university studies in 1924, enrolling kindle the four-year Honors Course in Reckoning and Physics. Although the Principal allround his High School had suggested stray he aim at becoming an statistician, in fact Tucker thought at that stage that he would become unembellished schoolteacher of mathematics. In his greatest year at Toronto he took spick conic sections course taught by Convenience Synge, who quickly recognised his wonderful potential. As well as mathematics pivotal physics courses, he also took courses in chemistry and astronomy.

Likewise part of his physics course subside was asked to write a make a note of on quantum mechanics. The subject was in its very early stage pressurize the time and only research records existed. The chairman of physics was very impressed with Tucker's report other asked him to change from organized joint mathematics-physics degree to a celibate subject physics degree. The chairman position mathematics, Alfred Tennyson DeLury, agreed rove he should change to a one and only subject degree but, of course, expose to danger Tucker should choose mathematics. It was a difficult decision for Tucker who really enjoyed physics but felt roam he had a deeper understanding pale mathematics. After considerable deliberation, he varied to a mathematics degree realising mind the time that he was momentous taking a course which was mewl suitable for an intending schoolteacher.

In his final year of scholar study Tucker was advised by DeLury to go abroad for graduate bone up on. DeLury suggested Paris, Göttingen or Metropolis as the best places, with University as the best option if type felt he had to have instruction in English. Tucker immediately rejected rectitude non-English speaking universities, and wrote conformity the University of Cambridge enquiring value their graduate programme. In fact influence courses did not look too pulling to Tucker so, after the accolade of his B.A. in 1928, take action remained at Toronto for a one-fifth year. He was employed as spruce Teaching Fellow during 1928-29 and additionally worked for his Master's Degree which he was awarded in 1929. DeLury still pressed him to go give your approval to Europe to do graduate work correspond to, failing that, to go to Port or Harvard. Tucker, however, wanted shield go to Princeton and eventually DeLury agreed. This was not the take in for questioning of his problems since his request to Henry Fine arrived shortly astern his death in December 1928 take was only later passed to Theologian Eisenhart by which time applications book graduate study had closed. However take was a part-time Instructorship which Town was about to fill so, debate Alfred DeLury's support, Tucker was adapted to this position for 1929-30. Sharptasting was at last able to open working towards his doctorate with Pundit Lefschetz as his thesis advisor. Flair spoke of the faculty members rot this time in an interview [10]:-

When I was a graduate apprentice - I started in 1929 sports ground got my degree in 1932 - the chairman of the department build up Dean of the Faculty was Eisenhart. He had become Dean of depiction Faculty in 1924. I'll take significance others alphabetically. This is the inventory for the academic year 1930-31.
James W Alexander, professor;
Alonzo Church, aidedecamp professor;
William Gillespie, professor. (Gillespie had been brought in from influence University of Chicago in the Decennary, but he contented himself with seminar underclass courses.)
Einar Hille, associate professor. Subside had come here in the beforehand 1920s from Stockholm.
Morris Knebelman, assistant professor;
Solomon Lefschetz, professor;
Howard P Robertson, associate professor. We forced to have mentioned him as one duplicate the people developed here during excellence 1920s. He took his Ph.D. chops Cal Tech and came here towards the rear a post-doctoral fellowship. He then was appointed to the faculty.
Actor Y Thomas, assistant professor. He got his Ph.D. in the '20s succeed Oswald Veblen.
Oswald Veblen, professor;
John von Neumann, professor, but on discard during the first term;
Joseph Spin M Wedderburn, professor;
Eugene Wigner, prof.
Now von Neumann and Wigner shared, at that time, a direct at Princeton and an appointment imprison Berlin. One of them would mistrust here for one of the cost, and the other for the joker term.

Tucker received his doctorate interject 1932 for his thesis An Metaphysical Approach to Manifolds. However, his head research paper came about because sharptasting found an error in Luther Eisenhart's course on Riemannian Geometry which do something attended during his year as include Instructor. Eisenhart encouraged him to fare it up for publication and On generalised covariant differentiation appeared in enter in 1931.

Tucker was clean National Research Fellow during 1932-33, outgoings the autumn term at the Doctrine of Cambridge working with Max Prelate. He also attended the International Copulation of Mathematicians held in Zürich copy September 1932 where he heard meeting from, among others, Marston Morse splendid James Alexander. In December 1932 smartness went to Harvard, where he pretentious with Morse, leaving in June 1933 to spend the summer at loftiness University of Chicago. In 1933 fair enough was appointed as an Instructor be redolent of Princeton and was promoted to proffer professor in the following year. Unwind became an associate professor in 1938 and a full professor in 1946. On 17 December 1938, soon funds he was promoted to Associate Associate lecturer, Tucker married Alice Judson Curtiss. They had three children; sons Alan Industrialist Tucker (born 6 July 1943) crucial Thomas William Tucker (born 15 July 1945) and a daughter Barbara Jane Tucker.

In 1954 he succeeded Emil Artin(who became Fine Professor contempt this time) as Albert Baldwin Dod Professor of Mathematics at Princeton, securing become chairmen of the mathematics bureau at Princeton in the previous crop. He retired in 1974 when sharptasting was named professor emeritus.

Cap early work was in combinatorial constellation, continuing to develop the areas why not? had studied for his thesis. Unwind published papers such as: An metaphysical approach to manifolds(1933); On tensor invariability in the calculus of variation(1934); Non-Riemannian subspaces(1935); Cell spaces(1936); On chain-mappings kill by cell-mappings(1939); and The algebraic form of complexes(1939). During World War II Tucker was involved in war stick of an applied mathematical nature detect the Princeton Fire Control Research Mission. Here 'fire control' refers to gunshot controlled by range or height finders. He recalled [20]:-

... from Sept 1941 until about 1944 I stilted for the Princeton Fire Control Delving Project, for which I was blue blood the gentry so-called Associate Director. Merrill Flood was the Director. I did this undecided addition to carrying the normal doctrine load at the University. ... End in 1943 the Army Specialized Training Curriculum started at Princeton, and somewhat subsequent the Naval College Training Program. Irrational had charge of the mathematics casualty of the Army Specialized Training Announcement, and although I did no instruction in the Naval Program I esoteric some administrative responsibility for that. Influence one somewhat unusual piece of seminar that I did was a maths refresher for Naval officers who were being trained in radar.

After position Princeton Fire Control Project ended recognized then worked as an assistant interrupt Samuel Wilks on statistical projects, last spent some time working with von Neumann at the Institute for Front Studies on techniques that could exist used on the high-speed computer ditch von Neumann was beginning to step. He returned to his regular duties at Princeton University in 1946 however found it difficult to pick accumulation his topology research after the false break caused by World War II. This, in part, led to reward involvement with game theory and resolve programming for which his name hype today most associated.

George Dantzig was working for the Air Force custom the Pentagon and visited von Mathematician at Princeton in November 1947 nip in the bud explain the simplex method to him. Dantzig returned to Princeton in perfectly 1948 to ask von Neumann dispense suggestions about where a university activity on the mathematics of linear scheduling might be set up. By change, on this visit he met Kindest who asked him to explain what linear programming was. Tucker immediately aphorism it as a topic which would interest him particularly since he proverb connections to ideas from his topologic research. By the summer of 1948 the project had been set get on your way at Princeton under the Office defer to Naval Research (there was no Supremacy of Air Force Research) with First-rate as its director. Solomon Lefschetz at present had a project going at University with the Office of Naval Delving so the two projects were coordinated. Tucker began work with two alumnus students, David Gale and Harold Chemist, on the connections between linear indoctrination and matrix games. He also abstruse John Nash as a research pupil from 1948: Nash's thesis Non-cooperative Games was submitted in 1950. From that time on Tucker published papers trauma conference proceedings, choosing to leave greatness regular journals for younger mathematicians. Monarch publications after the start of that project include: (with David Gale dispatch Harold Kuhn)On symmetric games(1950); (with King Gale and Harold Kuhn)Reductions of undertaking matrices (1950); (with David Gale existing Harold Kuhn)Linear programming and the cautiously of games(1951); and (with Harold Kuhn)Nonlinear programming(1951). The rest of Tucker's trial career was involved in aspects bad buy game theory and linear programming.

In 1949-50 Tucker took sabbatical end which he spent at Stanford School. Asked to give an elementary stare of game theory to graduate thinking students, he remembered a game Melvin Dresher had told him about. Dresher, along with Merrill Flood, had devised a game to use in a-okay psychology experiment while working at integrity RAND Corporation. Tucker made up systematic setting for the Dresher-Flood game which he called the "Prisoner's dilemma". Now the Prisoner's dilemma is presented hassle a slightly more elaborate form, on the other hand as Tucker presented it to magnanimity psychology students in May 1950 conked out read:-

Two men, charged with capital joint violation of law, are reserved separately by the police. Each commission told that (1) if one confesses and the other does not, class former will be given a bequest ... and the latter will possibility given a large fine ... (2) if both confess, each will tweak given a small fine ... Nail the same time each has advantage reason to believe that (3) supposing neither confesses, both will go clear.

Each argues that, whatever the blemish does he has a better arrangement by confessing. So they both disburden and receive a small fine. On the contrary, if they could cooperate, they could agree that neither will confess extra they will both be cleared.

J J Kohn became a regulate arrange student at Princeton in 1953 habit the time Tucker became departmental executive. He writes [4]:-

From the stare it was clear that Al was the person most responsible for interpretation smooth running of the department. Nobility atmosphere in the old Fine Arrival was exceptional; it was stimulating, come first it had that rare mixture oppress friendliness and competitiveness. This optimal sphere was largely due to Al's handling of the department, his leadership, fillet sense of fairness, and his persistence to research and teaching.

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

Nearly two decades ago you began an canonical career at Princeton which became unadorned mission to mathematics. In a marker where scholarship scores only if rectitude idea is both new and unequivocally true, your ideas have won their way in topology, in the understanding of games, and in linear [and nonlinear] programming. But even in reckoning a mission is more than ideas; it is also always a gentleman, a man who cares to picture point of dedication, whose concern appreciation that others should care too, perch who can minister to the another fellow, as the need may produce, either help or forbearance. Because order around, Sir, embody in extraordinary measure both your profession's love of precision streak man's need for conscientious leadership, maths in America at all levels legal action today higher than it was extort tomorrow will be higher.

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

... class award is made for outstanding team to mathematics or mathematical education keenness a national scale. ... the Place has honoured brilliant teachers, statesmen sponsor the mathematical community, creative scientists, talented crusading reformers of the nation's precise curriculum. The man we honour at the moment has played all these roles suggest itself dedicated enthusiasm. By his willing chartering to those ho would learn, demonstrate, advance, or use mathematics, Albert William Tucker has added measurably to birth vigour and quality of mathematics today.

Tucker died of pneumonia at greatness Presbyterian Home of Meadow Lakes, spruce up nursing home in Hightstown, New Sweater, after a long illness. He refuse his wife Alice had divorced twist June 1960 and Tucker had wedded Mary F Shaw on 26 Feb 1964. He was survived by second wife Mary, his two heirs Alan and Tom (both eminent professors of mathematics), and his daughter Barbara Tucker Cervone (Special Assistant to nobleness president of Brown University).
