Shimshon Amitsur

Shimshon Avraham Amitsur, born Kaplan in Jerusalem on August 26, 1921, was an Israeli mathematician and a leading figure in twentieth-century noncommutative algebra, best known for his wide-ranging contributions to ring theory, including rings with polynomial identities, division algebras, the general theory of radicals and the Amitsur complex in descent theory. His collected works were published in two volumes by the American Mathematical Society in 2001. He began his studies at the Hebrew University of Jerusalem in 1938 under Jacob Levitzki, and after Levitzki's death in 1956 became the leading algebraist in Israel, remaining a dominant figure in the field until his death on September 5, 1994.
