April 12, 1915–August 3, 1991


PROFESSOR PERLMAN HAD outstanding success in six major careers. He pioneered many advances made in nuclear medicine prior to World War II, particularly the use of radioactive iodine and phosphorus in physiological tracer studies. He played a key role in the development of plutonium production facilities for World War II, and was a leader of research in an intensely important project with a very tight schedule. His research contributed greatly to an understanding of the nuclear structure of the heavy elements, and he was considered a world leader on the systematics of alpha decay. He developed high-precision methods of neutron activation analysis at the Lawrence Berkeley Laboratory, developed procedures to determine the origin of ancient pottery and other artifacts from the data, and was regarded as a top expert in the field of archaeometry. He developed a new neutron activation analysis facility at the Hebrew University of Jerusalem, which became one of the top laboratories in the world for determining the origin of ancient artifacts, and which also produced some outstanding contributions in the field of geology. After returning to Berkeley, he helped develop handling procedures for measuring iridium abundances in large numbers of samples
