Monty Hall was born Monty Halperin on August 25, 1924 in Winnipeg, Manitoba, Canada. Hall attended the University of Manitoba, graduating in 1945, and served in the Canadian Army during World War II.
Monty Hall immigrated to the United States in 1955, and for the next few years worked in radio and television for the NBC and CBS networks. In 1963, Hall began as emcee for the game show Let's Make a Deal, the role that would make him famous. Except for brief interruptions, Let's Make a Deal ran on various US television networks for the next 23 years. The show was notorious for the outrageous costumes of the contestants.
In addition to his show business fame, Monty Hall is now immortalized (at least for students of probability) for the probability problem that bears his name. The controversy concerning the problem began with a column by Marilyn Vos Savant in the Sunday newspaper supplement Parade.
Monty Hall lives in Beverly Hills, California with his wife Marilyn; they have three grown children. He is active in fundraising for various charities, and still does occasional television roles.
