Extractions: Donald Coxeter is always known as Donald which comes from his third name MacDonald. This needs a little explanation. He was first given the name MacDonald Scott Coxeter, but a godparent suggested that his father's name should be added, so Harold was added at the front. Another relative noted that H M S Coxeter made him sound like a ship. A permutation of the names resulted in Harold Scott MacDonald Coxeter. Donald was educated at the University of Cambridge, receiving his B.A. in 1929. He continued to study for a doctorate at Cambridge under H F Baker , and this was awarded in 1931. He then became a Fellow continuing his researches at Cambridge. During this period he spent two years as a research visitor at Princeton University working under Veblen . He was Rockefeller Fellow during 1932-33 and Procter Fellow during 1934-35. In 1936 Coxeter took up an appointment at the University of Toronto. He has remained on the faculty at Toronto ever since and recently a celebration was held in the department to celebrate his 60 years at the University of Toronto.

Prix Coxeter-James Biographical Information HSM (donald) coxeter (Seventh President of the CMS 19651967).donald coxeter was born in Kensington (London), February 9, 1907. http://www.cms.math.ca/Prix/info/cj.html
Extractions: Biographical Information: Donald Coxeter was born in Kensington (London), February 9, 1907. His parents were Lucy Gee (who painted portraits and landscapes) and Harold Samuel Coxeter (a manufacturer of surgical instruments and anaesthetics, with singing and sculpture as hobbies). He attended Trinity College, Cambridge, from 1926 until 1936, first as a scholar then as a fellow. He studied for his Ph.D. under H.F. Baker and then spent two separate years at Princeton, attending lectures by Weblen, Alexander, Lefschetz, Wedderburn, Eisenhart and Weyl. His first visit to Canada was in 1934, when Gilbert de B. Robinson urged Samuel Beatty to invite him from Princeton to Toronto as a colloquium speaker. Apparently Beatty was sufficiently impressed to send a telegraphic message in 1936 offering Coxeter an assistant professorship. That came just before his marriage to Rien Brouwer, a lovely young lady from The Hague. They travelled by ship to settle in Toronto. Ralph James was born in Liverpool, England, in 1909 and came to Vancouver at a young age. He graduated from the University of British Columbia in 1928 with first class honors in Mathematics, and took a master's degree under Frederick S. Nowlan. Nowlan persuaded and helped him to go to Chicago for a Ph.D. which he completed in 1932 under Leonard Eugene Davidson; his thesis was on Waring's Problem.
Prix Jeffery-Williams donald coxeter's letter refers to his absentmindedness . G. de B. Robinsonfirst met Lloyd at the Royal Society meeting in Montreal in 1936. http://www.cms.math.ca/Prix/info/jw.html
Extractions: Biographical Information: Ralph Jeffery was born on October 3, 1989 in Overton, Yarmouth County, Nova Scotia. He left school in the middle of Grade 8 to join his father as a fisherman. However, at age 21 he sent out to up-grade his academic qualifications and was soon Principal of Port Maitland High School. He married Nellie Churchill of Overton who encouraged him to enroll in Acadia University. Graduating in 1921 with a major in economics and having taken one course in Calculus and one in Analytic Geometry, he embarked on graduate work in mathematics at Cornell followed by a year at Harvard. Except for a leave in 1928 when he completed a Ph.D. at Cornell and one term in 1938 acting as Head of Mathematics at the University of Saskatchewan, he served as Head of Mathematics at Acadia from 1924 to 1942. He was elected a Fellow of the Royal Society of Canada in 1937. Jeffery accepted the position of Head of Mathematics at Queen's University in 1942 partly in order to get closer to mathematics research activity. He encouraged good undergraduate teaching, built up a flourishing research and graduate program and served for many years as Chair of the Board of Graduate Studies. His contributions to Queen's University were commemorated in the naming of Jeffery Hall. Upon his retirement in 1960, Jeffery returned to an active teaching role at Acadia until his death in 1975. In his 85th year, he taught three full courses! His first wife died in 1956 and, in 1970, he married Frances Lewis of Bedford.
PIMS Changing The Culture 2000: Public Lecture Born 9 Feb 1907 in London, England, donald coxeter is always known as donald whichcomes from his third name Macdonald. This needs a little explanation. http://www.pims.math.ca/education/2000/CtC/coxeter/
Extractions: after the start. Abstract: While the public lecture by H.S.M. Coxeter will touch on various mathematical aspects of M.C. Escher's art, its centre-piece is likely to be an examination of Escher's circular woodcuts. The following is Coxeter's introduction (with two minor verbal substitutions for mathematical notation) to a paper which appeared in the Mathematical Intelligencer , No.4, 1966. Born 9 Feb 1907 in London, England, Donald Coxeter is always known as Donald which comes from his third name MacDonald. This needs a little explanation. He was first given the name MacDonald Scott Coxeter, but a godparent suggested that his father's name should be added, so Harold was added at the front. Another relative noted that H M S Coxeter made him sound like a ship. A permutation of the names resulted in Harold Scott MacDonald Coxeter. Donald was educated at the University of Cambridge, receiving his B.A. in 1929. He continued to study for a doctorate at Cambridge under H F Baker, and this was awarded in 1931. He then became a Fellow continuing his researches at Cambridge. During this period he spent two years as a research visitor at Princeton University.
Mathematics Meets Art For Prof. Coxeter where Prof. coxeter teaches. But donald coxeter (he uses a shortenedform of his third name, Macdonald) is not done yet. In a book http://www.math.toronto.edu/coxeter/art-math.html
Extractions: By Stephen Strauss At 89, H.S.M. Coxeter is what he has been his whole professional life: a mathematician inordinately skilled at geometry a master geometer. He has been publishing in the field for 70 years, has worked professionally at the University of Toronto for 60 years, and has nine honorary doctorates, 12 books and 167 published articles to his credit. He is so famous in his field that mathematicians around the world identify the University of Toronto as the school where Prof. Coxeter teaches. But Donald Coxeter (he uses a shortened form of his third name, MacDonald) is not done yet. In a book-rich office, the frail-looking but erect master geometer talks excitedly about his latest project. He is about to publish a paper that proves Dutch graphic artist M.C. Escher got it mathematically perfect in one of his etchings. The work in question is Escher's Circle Limits III . It is an arabesque of intersecting arcs within a circle. For the past three months, Prof. Coxeter has been trying to find out how accurately Escher, who knew almost no mathematics, was able to repeat the same arc angles of intersection. After half a page of trigonometric calculations, he determined that if Escher wanted to construct his painting from mathematical first principles, he would have used an arcane formula involving the cosine of an angle and the hyperbolic sine of a logarithmic function.
