For the paper "Creation of Cleavage Steps by Dislocations"

AIME Rossiter W. Raymond Memorial Award in 1959

Dr. Gilman was horn in St. Paul in 1925. After spending the years 1943 to 1946 on active duty in the U. S. Navy, he received a B.S. from the Illinois Institute of Technology in 1946 and an M.S. in 1948. He was a Campbell Fellow at Columbia University in 1949 and 1950 and was awarded his Ph.D. in 1952.

Elected to membership in AIME in 1947, he served as Chairman of the Physics and Chemistry of Metals Committee of the Institute of Metals Division in 1958.

Dr. Gilman is a Research Associate with the Physical Metallurgy Section, Metallurgy and Ceramics Research Department of the General Electric Research Laboratory in Schenectady. His work. is in the field of the plasticity and fracture of crystals and interpretation in terms of dislocations. For this work, he received the A. H. Geisler Award from A.S.M. in 1957. In 1956, he was also the recipient of the Rossiter W. Raymond Award from AIME.
