Hal died in Princeton July 10, 2025, at age 90.

Born May 20, 1935, in Chicago, he completed undergraduate work at the Illinois Institute of Technology in 1957, earned a master’s degree in theoretical physics at UCLA in 1959 and an MPA from the Woodrow Wilson School in 1963. Joining the science bureau of the U.S. Arms Control and Disarmament Agency, he wrote the safeguards article for what became the 1968 Nuclear Nonproliferation Treaty.

Hal returned to Princeton in 1967 and earned his Ph.D. in public affairs in 1972. His dissertation focused on the danger of weapons programs emerging from civilian nuclear energy technologies.

Hal remained at Princeton as a teacher, research scientist, and academic adviser to the men’s basketball team. His seminar, Scientists Against Time, explored contributions of scientists, engineers, and mathematicians during World War II. His collaborations on books and publications included Nuclear Proliferation: Motivations, Capabilities and Strategies for Control, with Ted Taylor, and A Blueprint for Deep Cuts and De-Alerting of Nuclear Weapons, with Bruce G. Blair and Frank von Hippel. Hal also wrote about the environmental impact of nuclear power.

Hal is survived by his wife of 51 years, Carol; children Dan, Peter, and Laura; four grandchildren; and brother Arthur.
