“I could be bounded in a nutshell and count myself a king of infinite space.”
—William Shakespeare, Hamlet, Act II, Scene 2

(as cited by Coxeter regarding “The Finiteness of Triangles,”
Introduction to Geometry)

As a companion to King of Infinite Space, the recently published biography of Donald Coxeter, this website provides photographs, archives, papers, video footage, links and other resources, allowing readers to further explore Donald Coxeter’s infinite passion for geometry.

These pages, hosted by the Mathematics Department at York University in Toronto, are very much a work in progress, with new items added regularly. Please feel free to get in touch with any suggestions or comments. The ultimate aim is to provide a clearinghouse, of sorts, for all things Coxeter — a repository useful both for recreational and academic investigation.
