A graduate of Collingswood (N.J.) High School, at Princeton he majored in physics, was a research assistant in the Cosmic Ray Lab, a participant in Roy Heath’s Advisee Project, and a member of Terrace Club.
Hal earned a doctorate in nuclear physics at Cornell University in 1958, where he met and married Sally Ann Moseley. He began his distinguished 60-year career in research on particle physics with Argonne National Laboratory. He enjoyed occasional sabbaticals and research assignments at CERN, Los Alamos, SLAC, DESY, and Fermi Lab.
Hal was an avid skier, loved to fish, and traveled extensively, with a particular passion for Paris. He remained a loyal Princetonian, and was proud of his record of never failing to contribute to Annual Giving. He was torn over missing his 65th reunion, and despite his illness, his blood continued to flow orange and black.
Hal is survived by Sally; three children, Kimberly, Matthew ’84, and Mark; seven grandchildren; and his brother Knute.
