Desi Arnaz was born on March 2, 1917, in Santiago, Cuba, into a prominent family. In 1933, following political unrest in Cuba, the family was forced to flee to Miami, where they initially lived in an abandoned warehouse and worked a series of menial jobs. Arnaz pursued his passion for music during this difficult period, eventually catching the eye of bandleader Xavier Cugat, who became his mentor. He returned to Miami in the late 1930s to form his own orchestra and introduced the conga line dance to the American public. His popularity led to nightclub appearances in New York and a role in the Broadway musical Too Many Girls in 1939.
It was on the set of the 1940 film adaptation of that musical that Arnaz met Lucille Ball. The two married that same year. After serving in the USO during World War II entertaining injured soldiers in California, Arnaz resumed his music career, with "Babalú" becoming his signature song by 1946. When Ball was cast in a radio program and plans were made to move it to television, she suggested Arnaz costar with her. Network executives resisted, concerned that American audiences would not accept Arnaz's Cuban accent. To prove them wrong, the couple took their act on the road. I Love Lucy premiered on October 15, 1951, and became the most popular show in America for four of its six prime time seasons.
Beyond his performance, Arnaz transformed how television was made. He insisted on filming in Los Angeles rather than broadcasting live from New York, used high quality 35mm film instead of kinescope, introduced multiple cameras, and welcomed a live studio audience — innovations that became the standard blueprint for the modern sitcom and made reruns and syndication possible. Desilu Productions, the company he and Ball founded, went on to produce some of the most celebrated series in television history, including The Untouchables, Mission Impossible, and Star Trek. In 1957 the couple purchased RKO Studios, one of Hollywood's most storied lots. Arnaz passed away on December 2, 1986, leaving behind a legacy that permanently changed American entertainment.
