Michael Sela

A member of the American Society for Biochemistry and Molecular Biology since 1968, Sela was the sixth president of the Weizmann Institute of Science and founding director of its immunology department.

Sela was born Miechzslaw Salomoniwicz in Poland on Feb. 28, 1924. Rising antisemitism drove his family first to Romania, and then to Palestine, where Sela arrived at age 17. He earned a master’s degree in chemistry at the Hebrew University in 1946, then moved to Italy to help resettle Jewish refugees and served as a diplomat in Prague. In 1950, he went to the Weizmann Institute as a doctoral student of Efraim Katzir, later a president of Israel. He earned a Ph.D. in chemistry through Hebrew University.

Sela’s work on synthetic antigens helped illuminate how genes control the immune response. He was one of the first chemists to create multichain polymers of amino acids and polypeptide proteins. This basic science indirectly led to his co-inventing the drug Copaxone (glatiramer acetate) for multiple sclerosis and three cancer drugs cetuxibab, necitumumab and panitumumab.

In addition to serving as president of the Weizmann Institute from 1975 to 1985, Sela led the International Union of Immunological Societies, chaired the Council of the European Molecular Biology Organization and joined the Global Advisory Committee of the World Health Organization. He was a member of the Israel, U.S. National, Russian, French and Pontifical academies of sciences.

Among many honors, Sela received the 1980 Gairdner Foundation International Award, UNESCO's Albert Einstein Golden Medal in 1995 and the 1998 Wolf Prize in Medicine, shared with his first grad student, Ruth Arnon.

Sela enjoyed and supported the performing arts, from the Batsheva Dance Company to classical music, jazz, theater and opera. He was a gifted linguist, who mastered  Polish, Romanian, Hebrew, German, Russian, French, English, Italian and Czech.

Sela’s first wife, Margalit Liebman, died in 1975. He is survived by his wife, Sara Kika; daughters, Irit, Orlee and Tamar, and their spouses; grandchildren; and great-grandchildren.
