For the paper "Energy-Size Relationships in Comminution"

AIME Rossiter W. Raymond Memorial Award in 1958

Richard J. Charles was horn in Elfros, Sask., Canada, in 1925. He received a B.S. degree in Mining Engineering from the University of British Columbia in 1948. Awarded the Britannia Mining and Smelting Co. Scholarship, he continued at the University as a Research Assistant and obtained an M.S. degree in Metallurgical Engineering in 1949.

After a period of time in the base metals and gold mining areas of British Columbia, Dr. Charles entered the Department of Metallurgy at Massachusetts Institute of Technology in 1951 and studied under Professors A. M. Gaudin and P. L. de Bruyn. He was granted an Sc.D. degree in 1954 and then joined the MJ.T. faculty as an Assistant Professor of Mineral Engineering. He continued in that capacity until 1956 when he assumed his present position as Research Associate in the Metallurgy and Ceramics Department of the General Electric Research Lahoratory at Schenectady, N. Y.

Dr. Charles has contributed to the technical literature on the subjects of particle size analysis, comminution and brittle fracture. He was elected a Junior Member of AIME in 1955.
