Frank Morgan
(Professor Marvel/The Wizard of Oz)

Though best known for his portrayal of the Wizard, Frank Morgan was a veteran of Hollywood long before he landed the title role in the MGM film. (In fact, the versatile Morgan played five roles in the film, including the Emerald City Doorman, The Cabbie and Guardian of the Emerald City Gates.) Born in 1890, Morgan got his start in silent movies and made the transition to "talking pictures" in both comic and dramatic supporting roles. Some of his many film credits include The Three Musketeers (1948), Tortilla Flat (1942 -- another Victor Fleming film, for which Morgan received one of his two Academy Awards®) and The Shop Around the Corner (1940). In an odd stroke of coincidence, Morgan found the name L. Frank Baum sewn into the pocket of the coat he wore as Professor Marvel. As it turned out the coat had been purchased by MGM with other used clothing and was later verified to have indeed belonged to Oz's creator.
