         William T. Tutte is one of the leading experts in graph theory and 
          matroid theory worldwide. He is responsible for some of the most fundamental 
          results in both of these fields; to mention just a couple, in graph 
          theory, he established the fundamental theorems of matching theory, 
          an important branch of combinatorial optimization, and in matroid theory, 
          he characterized regular matroids in terms of excluded minors, one of 
          the deepest results in the field.  
        Professor Tutte received his education at Cambridge University, graduating 
          with his Ph.D. in 1948. He joined the faculty of the University of Toronto 
          in 1948 and moved to the University of Waterloo in 1962. He was for 
          a long time the editor of the Journal of Combinatorial Theory and is 
          the Honorary Director of the Centre for Applied Cryptographic Research. 
          He is a Fellow of the Royal Societies of London and Canada. The CRM-Fields 
          prize recognizes exceptional achievement in mathematical research conducted 
          primarily in Canada or in affiliation with a Canadian university.
