New York Times obituary, June 7, 1982:

JULIUS ASHKIN, 61, PHYSICIST, DIES

Dr. Julius Ashkin, professor of physics at Carnegie-Mellon University since 1958 and chairman of the department from 1961 to 1972, died Friday at Montefiore Hospital here. He was 61 years old.

Dr. Ashkin, a leader in both theoretical and experimental physics, is noted for three major accomplishments. The first was a detailed theoretical analysis of the interaction of particles and radiation on passage through matter. He was co-author of this work in 1953 with Hans Bethe, who won the 1967 Nobel Prize in Physics.

Dr. Ashkin's second major work involved experiments with the unstable particles called pi mesons in the university's synchrocylotron, a device used in atomic research that gives positive and negative charges to such particles.

His third major contribution concerned an experiment with collaborators at the International Laboratory in Geneva involving the decay of the pi meson.

Dr. Ashkin was born in Brooklyn. He received his bachelor's degree in 1940, his master's in 1941 and his Ph.D. in 1943, all from Columbia University. He was a research associate at the University of Chicago in 1942 and 1943 on the Manhattan Project, which developed the atomic bomb, and a staff member at the atomic research laboratory at Los Alamos, N.M., from 1943 to 1946.

He is survived by his wife, Claire, and two daughters, Beth Gibboney of McLean, Va., and Laura Ashkin of Portola, Calif.
