Some Hispanics in the entertainment business served in the United Service Organizations (USO), which provided entertainment to help troop morale. One notable USO entertainer was Desi Arnaz, the Cuban bandleader who starred opposite Lucille Ball in the television show "I Love Lucy". When he was drafted into the army in 1943, he was classified for limited service because of a prior knee injury. As a result, he was assigned to direct the U.S.O. programs at a military hospital in the San Fernando Valley, California, where he served until 1945.
