Henry Linschitz, of Waltham, who worked on the Manhattan Project and served as a professor of chemistry at Brandeis from 1957-89, died on Nov. 24, 2014. He was 95. He grew up in New York City, graduated from City College of New York and earned his doctorate in chemistry at Duke University. During World War II, he worked at the Explosives Research Laboratory and then as a section leader at Los Alamos, N.M. He participated in the first atomic-bomb test at Alamogordo, and served on Tinian with the U.S. Air Force. After the war, he studied with James Franck as a postdoctoral fellow at the University of Chicago, then worked as a professor of chemistry at Syracuse University from 1948-57. He also taught at Hebrew University and the Weizmann Institute. Like many veterans of the Manhattan Project, Henry was active in the anti-nuclear and peace movements. His national service included several government panels, study sections and committees. He was a member of the American Academy of Arts and Sciences. He leaves his wife of 50 years, Suzanne Hodes ’60; his son, Joseph; and two grandchildren. Eli Sagan, P’81, of Dedham, Mass., who took great pride in his inclusion on Richard Nixon’s list of political enemies, died on Jan. 4. He was 87. After retiring as president of the New York Girl Coat Co., which his father founded, the Harvard graduate went on to author six books in the area of cultural sociology, including “At the Dawn of Tyranny: The Origins of Individualism, Political Oppression and the State” and “Freud, Women and Morality: The Psychology of Good and Evil.” He taught at Brandeis (1993-98), the New School (1986-91) and the University of California, Berkeley (1981-86). He served on the national board of the Women’s, Gender and Sexuality Studies Program at Brandeis. In 1973, he made the White House’s list of 490 political enemies. “I feel honored,” Eli told a newspaper at the time. “I was disappointed that I wasn’t on the last one.” He was named a Nixon enemy for his support of Democratic Sen. George McGovern, the man whom the 37th president routed in the 1972 election. Eli leaves his wife of 65 years, Frimi; four children, Miriam, Rachel, Susannah ’81 and Daniel; his brother; and seven grandchildren. He is also survived by Susannah’s husband, Andrew Katz ’80. Frederic Sommers, of Chevy Chase, Md., the Harry A. Wolfson Chair of Philosophy at Brandeis for 30 years, died on Oct. 2, 2014. He was 91. “He had an astonishingly productive career, filled with moments of brilliance and startling originality,” Andreas Teuber, a Brandeis associate professor of philosophy, says. According to Teuber, Frederic discovered at an early age that he was interested in delving into philosophical problems rather than merely studying the history of what others thought and said. He made a pact with himself to take up only those problems for which he could at least imagine a solution. In 1982, he published his best-known work, “The Logic of Natural Language.” A native of New York City, Frederic studied mathematics at Yeshiva College as an undergraduate before pursuing a doctorate in philosophy at Columbia. He wrote his dissertation on the metaphysics of Alfred North Whitehead. He taught at Columbia for eight years before joining the Brandeis faculty in 1963. He retired in 1993. He leaves his wife, Christina; his sons, Saul and David; his brother, Sholom; and one grandchild.
