On February 12, 1940 producers Bob Maxwell and Frank Chase aired the first episode of the classic radio program 'Superman' and hired a reluctant
Clayton 'Bud' Collyer as its lead actor. By March 1, 1950, baritone voiced actor Michael Fitzmaurice took over as the Man of Tomorrow but he, unfortunately, was no match for Bud's ability to create distinctively different voices for the dual role. The curtains closed on the radio show on June 5, 1950.
