John von Neumann

Abstract

The Canadian Mathematical Congress held its meeting last summer in Edmonton, Alberta. Professor Dixmier of Paris lectured on Algèbres de von Neumann. Dr. Zassenhaus’ lectures on Group Theory started with von Neumann’s definition of infinitesimal operators and their commutators. Dr. Tucker of Princeton lectured on the Theory of Games — another subject which was partially founded by Dr. von Neumann and greatly enriched by his ideas. Von Neumann made important contributions to all parts of mathematics, excepting number theory and topology, and he left his mark on theoretical physics and economics. His work during the war was vital for the success of several projects, and his contributions to the national welfare and national security did not cease, but rather intensified with the termination of the war. He died as a member of the U. S. Atomic Energy Commission.
