Mathematician H.S. Coxeter (1907-2003) was considered one of the world's foremost geometers of the 20th century, the author of many books and a university professor in Canada. Kurt's interest in mathematics, and particularly his fascination with geometry inclined him to contact Coxeter about Segre's Figure--a figure of fifteen lines and fifteen points, with three points on each line--which Kurt had developed as a three-dimensional figure. Coxeter responded, and their correspondence is presented here.
