Richard Denning (March 27, 1914 – October 11, 1998) was an American actor who starred in science fiction films of the 1950s, including Unknown Island (1948), Creature from the Black Lagoon (1954), Target Earth (1954), Day the World Ended (1955), Creature with the Atom Brain (1955), and The Black Scorpion (1957). Denning also appeared in the film An Affair to Remember (1957) with Cary Grant and on radio with Lucille Ball in My Favorite Husband (1948–1951), the forerunner of television's I Love Lucy. Early years Denning was born as Louis Albert Heindrich Denninger Jr., in Poughkeepsie, New York. When he was 18 months old, his family moved to Los Angeles. After attending Manual Arts High School, he earned a Master of Business Administration degree from Woodbury Business College in Los Angeles. Plans called for him to take over his father's garment manufacturing business, but he developed an interest in acting. Denning enlisted in the United States Navy during World War II and served on submarines. Career Denning was perhaps best known for his recurring starring roles in science fiction and horror films of the 1950s, and playing husband opposite Lucille Ball on the radio series that led to I Love Lucy in which he was replaced by Desi Arnaz as Lucy's husband. Denning began acting in minor supporting and background roles through the 1930s and early 1940s until the start of World War II. According to Denning, his military service disrupted his acting career, and after his discharge it would be a year and a half before Paramount Pictures offered him more acting work. During that time, he and his family lived in a mobile home that he alternately parked at Malibu and Palm Springs. Denning's unemployment ended when he was hired to star on the radio opposite Lucille Ball in My Favorite Husband. The CBS Radio sitcom ran for 124 episodes from July 23, 1948 through March 31, 1951 and would evolve into the groundbreaking television sitcom I Love Lucy. CBS wanted Denning to continue as the husband in the new sitcom but Lucille Ball insisted that her real life husband, Desi Arnaz, play the part. The radio stint, however, led to a role on CBS television's series adaptation of Mr. and Mrs. North. On television, he starred as the title character in the 1950 syndicated adventure series Ding Howe and the Flying Tigers. He was cast as Dr.
