Dwight Weist, Jr. (January 16, 1910 - July 16, 1991) was an actor and announcer in the era of old-time radio. Weist was called "the man of 1,000 voices," primarily as a result of his work on The March of Time. His obituary in The New York Times explained, "Mr. Weist, who played Adolf Hitler and Franklin D. Roosevelt, among many others, received his nickname because of his ability to imitate a broad range of accents and ages." Weist even made an adjustment in 1935 after Hitler had surgery to create a milder, more soothing vocal tone. Some of Weist's friends watched as he listened to a speech by Hitler and immediately afterward spoke in the newer tone himself. When he was assigned roles of people with whose voices he was unfamiliar, he listened to them in newsreels and on radio to develop his impersonations.
