professor. Wald was elected to the American Academy of Arts and Sciences in 1948. He was elected to the National Academy of Sciences in 1950, the American Philosophical Society in 1958, and in 1967 was awarded the Nobel Prize for Physiology or Medicine for his discoveries in vision. In 1966 he was awarded the Frederic Ives Medal by the OSA and in 1967 the Paul Karrer Gold Medal of the University of Zurich. Wald spoke out on many political and social issues and his fame as a Nobel laureate brought national and international attention to his views. He was a pacifist and vocal opponent of the Vietnam War and the nuclear arms race. Speaking at MIT in 1969 Wald said, "Our government has become preoccupied with death, with the business of killing and being killed." In 1980, Wald served as part of Ramsey Clark's delegation to Iran during the Iran hostage crisis. With a small number of other Nobel laureates, he was invited in 1986 to fly to Moscow to advise Mikhail Gorbachev on a number of environmental questions. While there, he questioned Gorbachev about the arrest, detention and exile of Yelena Bonner and her husband, fellow Nobel laureate Andrei Sakharov (Peace prize, 1975). Wald reported that Gorbachev said he knew nothing about it. Bonner and Sakharov were released shortly thereafter, in December 1986. A member of the Circumcision resource center in Boston, he was one of the first scientists committed against circumcision but his article "Circumcision", rejected by the New York Times in 1975, was published in 2012 only by an English magazine (http://churchandstate.org.uk/2012/12/what-jewish-nobelist-george-wald-had-to-say-about-circumcision/ ). Wald died in Cambridge, Massachusetts. He was married twice: in 1931 to Frances Kingsley (1906-1980) and in 1958 to the biochemist Ruth Hubbard. He had two sons with Kingsley—Michael and David; he and Hubbard had a son—the award-winning musicologist and musician Elijah Wald—and a daughter, Deborah, a prominent family law attorney. He was an atheist. See also List of Jewish Nobel laureates Retinal References Further reading Goldstein, B. 2001. Sensation and Perception, 6th ed. London: Wadsworth. External links John E.
