 Harold Scott MacDonald Coxeter

Harold Scott MacDonald Coxeter (1907–2003) was a prominent British mathematician known for his work in the field of geometry, particularly in the study of polytopes, tessellations, and higher-dimensional spaces. He made significant contributions to several areas of mathematics, including topology and group theory. Coxeter is perhaps best known for his research on regular polytopes and the classification of geometric figures in various dimensions.
