Diana “Mousie” Lewis (September 18, 1919 – January 18, 1997) was an American film actress and a Metro-Goldwyn-Mayer contract star. Born in Asbury Park, New Jersey, Lewis began her film career in All the King’s Horses (1934) and worked steadily over the next few years, usually in minor roles. Her more notable films include It’s a Gift (1934), Gold Diggers in Paris (1938), Go West (1940) and Johnny Eager (1941). She was the love interest of Andy Hardy as Daphne Fowler in Andy Hardy Meets Debutante (1940). She met the actor William Powell (27 years her senior) in 1940, married after a courtship of three weeks and retired from acting in 1943. The couple remained together for forty-four years until Powell’s death at age 91 in 1984. Lewis died from pancreatic cancer in Rancho Mirage, California, aged 77. She was interred at Cathedral City’s Desert Memorial Park in Riverside County, California, alongside Powell, and her stepson, William David Powell. Lewis was an active supporter of women’s golf and the LPGA. The LPGA’s William and Mousie Powell Award is named in honor of the Powells. In 2000, a Golden Palm Star on the Palm Springs, California, Walk of Stars was dedicated to her.
