Captain Midnight

Where would Ovaltine be without Captain Midnight and the many secret decoder premiums that World War II-era boys and girls (but especially boys) anxiously sent in for? In 1939 a syndicated series, Captain Midnight and his Secret Squadron quickly moved to the Mutual network in 15 minute weekday episodes where it continued for nearly a decade. In the great tradition of secretive radio heroes, Midnight was the secret identity of a World War I flying ace, engaged in a never-ending battle against master criminal Ivan Shark and aided by curiously youthful companions.

Captain Midnight made the transition to television in the mid 1950s.
