Hayden Rorke was an actor whose career began on stage in the 1930s and in movies in the 1940s. He was adept at playing various characters. In the 1950s, he began an extensive career guest-starring on many tv shows.
In 1965, he played his most well-known role: 'Dr. Bellows' on the tv sitcom "I Dream of Jeannie", costarring with Barbara Eden and Larry Hagman. He continued in this role for the entire series, through 1970.
I wrote to Mr. Rorke in 1980, to his residence in Studio City, California. I requested a signed photo, and he sent this one, in character as 'Dr. Bellows'.
