In 1951, film actress Lucille Ball and her musician husband Desi Arnaz spent $5,000 to produce a TV sitcom pilot about a Cuban-born bandleader named Ricky Ricardo, his zany, starstruck wife Lucy, and their madcap life in a Manhattan apartment. The result was the decade’s biggest show and a landmark in TV history that ran until 1957. William Frawley and Vivian Vance co-star as the Ricardos’ best friends and neighbors, Fred and Ethel Mertz.
