Pugwash mourns the passing of Nobel Laureate Jack Steinberger, who died on December 12, 2020, at his home in Geneva at the age of 99. After 1945, he became an experimental physicist under Enrico Fermi and Edward Teller, and, after arriving at CERN in 1968, became director of experimental research in particle physics, thus becoming a leading and worldwide respected particle physicist. In 1988 he shared the Nobel Prize in physics (with with Leon E. Lederman and Melvin Schwartz) for expanding the understanding of the long-mysterious neutrino. Throughout his life, he joined other scientists in speaking out against nuclear weapons and American militarism. He declined to do weapons work and was a strong advocate for a world without nuclear weapons. He attended several Pugwash conferences, inter alia in Geneva, Germany, and Castiglioncello.
