Professor Bezalel Peleg (1936-2019)

With Bezalel Peleg’s death on May 9, 2019, the social choice and game theory communities have lost a pioneering and influential member. Bezalel Peleg completed his Ph.D. in mathematics at the Hebrew University of Jerusalem under the supervision of Robert Aumann in 1964. His first paper (Peleg 1959), on solvable n-person games, appeared in the Bulletin of the American Mathematical Society. He was a productive researcher during the last sixty years in which he was affiliated with the Hebrew University of Jerusalem. His scientific work covers many areas in economic theory, including cooperative and non-cooperative game theory, general equilibrium theory, and social choice theory. For an extensive bibliography and discussion of his work until 2012, see (Peters and Sudhölter 2012). Here, we just highlight a few topics that we believe are central in his work and were central in his mind.
