**Harold Scott MacDonald** "**Donald**" **Coxeter**, CC, FRS, FRSC (February 9, 1907 – March 31, 2003)^{[2]} was a British-born Canadian geometer. Coxeter is regarded as one of the greatest geometers of the 20th century.^{[3]} He was born in London, received his BA (1929) and PhD (1931) from Cambridge, but lived in Canada from age 29. He was always called Donald, from his third name MacDonald.^{[4]} He was most noted for his work on regular polytopes and higher-dimensional geometries. He was a champion of the classical approach to geometry, in a period when the tendency was to approach geometry more and more via algebra.^{[5]}

## Biography

In his youth, Coxeter composed music and was an accomplished pianist at the age of 10.^{[6]} He felt that mathematics and music were intimately related, outlining his ideas in a 1962 article on "Mathematics and Music" in the *Canadian Music Journal*.^{[6]}

Coxeter went up to Trinity College, Cambridge in 1926 to read mathematics. There he earned his BA (as Senior Wrangler) in 1928, and his doctorate in 1931.^{[6]}^{[4]} In 1932 he went to Princeton University for a year as a Rockefeller Fellow, where he worked with Hermann Weyl, Oswald Veblen, and Solomon Lefschetz.^{[4]} Returning to Trinity for a year, he attended Ludwig Wittgenstein's seminars on the philosophy of mathematics.^{[6]} In 1934 he spent a further year at Princeton as a Procter Fellow.^{[4]}

In 1936 Coxeter moved to the University of Toronto. In 1938 he and P. Du Val, H.T. Flather, and John Flinders Petrie published The Fifty-Nine Icosahedra with University of Toronto Press. In 1940 Coxeter edited the eleventh edition of *Mathematical Recreations and Essays*,^{[7]} originally published by W. W. Rouse Ball in 1892. He was elevated to professor in 1948. Coxeter was elected a Fellow of the Royal Society of Canada in 1948 and a Fellow of the Royal Society in 1950. He met M. C. Escher in 1954 and the two became lifelong friends; his work on geometric figures helped inspire some of Escher's works, particularly the *Circle Limit* series based on hyperbolic tessellations. He also inspired some of the innovations of Buckminster Fuller.^{[4]} Coxeter, M. S. Longuet-Higgins and J. C. P. Miller were the first to publish the full list of uniform polyhedra (1954).^{[8]}

He worked for 60 years at the University of Toronto and published twelve books.

## Awards

Since 1978, the Canadian Mathematical Society have awarded the Coxeter–James Prize in his honor.

He was made a Fellow of the Royal Society in 1950 and in 1997 he was awarded their Sylvester Medal.^{[4]} In 1990, he became a Foreign Member of the American Academy of Arts and Sciences^{[9]} and in 1997 was made a Companion of the Order of Canada.^{[10]}

In 1973 he received the Jeffery–Williams Prize.^{[4]}
