HAROLD SCOTT MACDONALD "DONALD" COXETER, FRS, FRSC, CC (February 9,
1907 – March 31, 2003) was a British-born Canadian geometer.
Coxeter is regarded as one of the greatest geometers of the 20th
century. He was born in
**London**

London but spent most of his adult life in
**Canada**

Canada . He was always called Donald, from his third name MacDonald.

BIOGRAPHY

In his youth, Coxeter composed music and was an accomplished pianist
at the age of 10. 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.

Coxeter went up to Trinity College , Cambridge in 1926 to read
mathematics. There he earned his BA (as
**Senior Wrangler**

Senior Wrangler ) in 1928, and
his doctorate in 1931. In 1932 he went to
**Princeton University** for a
year as a
**Rockefeller Fellow**

Rockefeller Fellow , where he worked with
**Hermann Weyl** ,
**Oswald Veblen** , and
**Solomon Lefschetz** . Returning to Trinity for a
year, he attended
**Ludwig Wittgenstein** 's seminars on the philosophy of
mathematics . In 1934 he spent a further year at Princeton as a
Procter Fellow.

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, originally published by
**W. W. Rouse Ball**

W. W. Rouse Ball in 1892. He was
elevated to professor in 1948. Coxeter was elected a Fellow of the
Royal Society of
**Canada**

Canada in 1948 and a
**Fellow of the Royal Society** in
1950. He met Maurits 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** . Coxeter,
**M. S. Longuet-Higgins** and J. C. P.
Miller were the first to publish the full list of uniform polyhedra
(1954).

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

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** . In 1990, he became a Foreign Member
of the
**American Academy of Arts and Sciences** and in 1997 was made a
Companion of the
**Order of Canada** .

In 1973 he received the
**Jeffery–Williams Prize** .
