Desiderio Alberto Arnaz y de Acha III, better known as Desi Arnaz, was a Cuban-American actor, musician, bandleader, comedian and film and television producer. He is best known for his role as the witty Ricky Ricardo on the American television series sitcom I Love Lucy, where he co-starred with his then wife, dramatic and comedic actress Lucille Ball. Arnaz and Ball are generally credited as the innovators of the syndicated rerun, which they pioneered with the I Love Lucy series.
Arnaz and Lucille Ball co-founded and ran the television production company called Desilu Productions, originally to market I Love Lucy to television networks. After I Love Lucy ended, Arnaz went on to produce several other television series, at first with Desilu Productions, and later independently, including The Ann Sothern Show and The Untouchables. He was also renowned for leading his Latin music band, the Desi Arnaz Orchestra.
