Description: Harold Scott MacDonald Coxeter, Professor Emeritus, Math Dept., Univ. of Toronto, is best known for his work in hyperdimensional geometries and regular polytopes - geometric shapes that extend into the 4th dimension and beyond. In 1926 he discovered a new regular polyhedron having six hexagonal faces at each vertex; in 1933 he enumerated the n-dimensional kaleidoscopes; and Coxeter polytopes, the fundamental domains of discrete reflection groups, are now called Coxeter groups.
