Donald Bures began his college work by winning a General Motors scholarship. He completed the four year mathematics program at Queen's University in three years and the M.A. and Ph.D. program at Princeton in three years. For his doctoral thesis he became an expert with infinite tensor products of von Neumann algebras and wrote a thesis which Professor C. C. Moore describes as 'a superb paper in a very difficult area'. This praise should not be taken lightily for Professor Moore is one of the outstanding analysts of this continent. Since then Bures has published four other articles, each of which made a solid contribution based on deep analysis and new techniques, yielding new and important results. These papers are appraised in the attached letters from Professors Moore, Glimm and Stormer. Although he is not yet very old, Professor Bures has directed several very good doctoral theses, namely those of: Charles Kerr, Ole Nielsen, David Promislow and P. K. Tam. Professor Bures' work is known to operator algebraists throughout the world and he is esteemed as one of the leading workers in the field.
