Weisstein April 2, 2003Noted geometer and author H. S. M. Coxeter passed away peacefully at his home in Toronto on March 31. He was 96. Known to friends and colleagues as "Donald," Harold Scott MacDonald Coxeter was originally to be named "MacDonald Scott" until a godparent suggested that his father's name "Harold" be added as his first name. At this point, another relative pointed out that "Harold MacDonald Scott" would give him the same initials as "Her Majesty's Ship" (as in, for example, Gilbert and Sullivan's well-known H. M. S. Pinafore ), and hence "Harold MacDonald Scott" became "Harold Scott MacDonald." Coxeter was born on February 9, 1907, in London. He was artistically gifted, especially in music, but decided to become a mathematician as a result of his love of the beauty of symmetry, an interest that was reflected in his work throughout his life. Coxeter received his B.A. in mathematics at Cambridge University in 1929, quickly followed by his Ph.D. in 1931. After briefly working as a fellow at Cambridge University and a visiting researcher at Princeton University, Coxeter accepted a position at the University of Toronto in 1936, where he taught and continued his research until his death this year.

(Donald) Coxeter (Seventh President of the CMS 1965-1967) 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. During the next fifty years, they crossed the Atlantic Ocean twenty-six times, the first three by ship. Those trips included visiting professorships at Amsterdam, Edinburgh, East Anglia, Canberra, Sussex, Utrecht and Bologna. He was awarded honorary degrees by the universities of Alberta, Waterloo, Acadia, Trent, Toronto, Giessen (Germany), Carleton, McMaster and York. Other honors that he has received include Fellow of the Royal Society of Canada (1948), Fellow of the Royal Society (1950), honorary membership in several mathematical societies, Foreign Member of the American Academy of Arts and Sciences (1990) and, in 1997, Companion of the Order of Canada.

Titulaires Appel de candidatures Prix 2005 Prix 2006 Biographical Information: Ralph Lent Jeffery (Fourth President of the CMS 1957-1961) Ralph Jeffery was born on October 3, 1889 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.

Korea: Seung San NATIONAL MAGAZINE AWARD-WINNER WRITES THE FIRST BIOGRAPHY OF A WORLD-FAMOUS AND FASCINATING MATHEMATICAL GENIUS, WHOSE WORK HAS HAD IMPORTANT APPLICATIONS IN MEDICINE, E-COMMERCE, ASTROCHEMISTRY, AND TELECOMMUNICATIONS FOREWORD BY DOUGLAS HOFSTADTER, AUTHOR OF GODEL, ESCHER, BACH PREFACE BY JOHN CONWAY, THE JOHN VON NEUMANN PROFESSOR OF MATHEMATICS, PRINCETON UNIVERSITY The Man Who Saved Geometry combines two best-selling categories, popular science and biography, to reveal the impact of geometry on everyday life and to make geometry accessible through the fascinating life of the world’s greatest living classical geometer. Columbia University physicist Brian Greene, New York Times best-selling author of The Elegant Universe , declares that geometry is a language crucial to explaining and uncovering the universe in which we live; there is perhaps no better way to anticipate the scientific breakthroughs of the future, he says, than through the knowledge and evolution of geometry. In this sense, for the masses of readers who are eager for books that make science accessible, Coxeter’s biography opens a fascinating new window onto our universe. The story of Donald Coxeter leads to the discovery of how geometry makes a practical impact on our everyday life, and how the world would be different if classical geometry had become extinct.

DONALD COXETER Né à Londres le 9 février 1907, de son vrai nom Harold Scott MacDonald Coxeter, il est mieux connu sous le surnom de Donald. Etudiant à l’Université de Cambridge, il obtient sa licence en 1929. En 1931, ayant acquis son doctorat à Cambridge même, il y reste pour poursuivre des recherches. Durant l’année 1936, un poste à l’Université de Toronto s’offre à lui, université pour laquelle il travaille depuis plus de 60 ans. Coxeter a surtout travaillé en géométrie où il a grandement contribué à l’évolution de la théorie des polytopes et à la géométrie non euclidienne. Ces polytopes sont des formes géométriques que l’on augmente d’une dimension, ce procédé étant appelé Dimensional Analogy. Ainsi, il étend la géométrie des polytopes à la quatrième dimension et même au-delà. Ce que motive Coxeter dans ses recherches est la beauté des mathématiques. D’ailleurs, Robert Moody de la York University de Toronto considère que les sciences modernes, dont en font partie les mathématiques, suivent une certaine mode. Ce qu’il trouve de remarquable au style de Coxeter est sa faculté d’échapper à un phénomène de mode et de n’être guidé que par ce qu’est la beauté. De plus, son goût pour les domaines artistiques est aussi marqué par son intérêt pour la musique. En effet, il aurait désiré être compositeur avant de se lancer dans les mathématiques. A l’âge de 14 ans, ayant trop de facilité à l’école, il imagine les formes géométriques en dimensions supérieures et rédige déjà ses premières idées à ce sujet. Son père, grand ami du philosophe Bertrand Russell, amène son fils chez celui-ci. Russell aide Coxeter à se trouver un excellent professeur de mathématiques, le Professeur H.F. Baker de l’Université de Cambridge.

Coxeter published in the geometrical field for 70 years, worked professionally at the University of Toronto for 60 years and wrote 12 books and more than 200 articles. He was best known for his work in hyperdimensional geometries and regular polytopes - complicated geometric shapes of any number of dimensions that cannot be constructed in the real world but can be described mathematically and sometimes drawn. In 1926, at 19, he discovered a new regular polyhedron with six hexagonal faces at each vertex. He went on to study the mathematics of kaleidoscopes and, by 1933, had enumerated the n-dimensional kaleidoscopes (kaleidoscopes operating up to any number of dimensions). His complex algebraic equations expressing how many images of an object may be seen in a kaleidoscope are now known as Coxeter groups. Coxeter's work on icosahedral symmetries played an important role in the discovery by scientists at Rice University, Texas, of the Carbon 60 molecule, for which they won the 1996 Nobel Prize in Chemistry. Carbon 60 is now being tested as a superconductor for use in everything from chemotherapy and telecommunications to AIDS research.
