Lucille Ball was born Lucille Désirée Ball on August 6, 1911, in Jamestown, New York. Her early career ran through modeling, B-picture acting, and a long association with RKO Pictures through the late 1930s and 1940s — a period during which she was productive, working steadily, but not a major star. The major star phase came from an unexpected direction: radio. Her CBS radio series *My Favorite Husband*, which ran from 1948 to 1951, established the comedic persona and the specific timing that would make *I Love Lucy* a television phenomenon.
The founding of Desilu Productions is itself a story about unconventional business instincts. Desi Arnaz, Ball’s husband since 1940, was a Cuban-born bandleader and musician whom CBS was initially reluctant to cast opposite Ball in the television adaptation of *My Favorite Husband*. The network’s objections to Arnaz were partly practical — they were uncertain whether American television audiences would accept an interracial couple — and partly creative: they saw Arnaz as a musician, not a comedian.
Arnaz and Ball solved the problem by going around the network. They formed Desilu Productions in 1950, funded the television pilot themselves, toured a stage version of the concept to prove that audiences would accept them as a couple, and negotiated a deal with CBS that gave Desilu ownership of the film prints and negatives of the episodes — a provision that would prove extraordinarily lucrative when reruns became standard practice.
*I Love Lucy* premiered on October 15, 1951. Within its first season it was the most watched show on American television. By the time the series concluded its original run in 1957, it had established Ball as the dominant female star of television and Desilu as a production entity of genuine importance.
