Tom Kelley Sr. (1914 – 1984) was an American photographer who photographed Hollywood celebrities in the 1940s and 1950s. He is best known for his iconic 1949 nude photographs of Marilyn Monroe, which were distributed widely as calendar art—one of which was featured in the inaugural issue of Playboy magazine. Kelley was born in Philadelphia, Pennsylvania. He learned photography as an apprentice in a New York photo studio, and then worked for the Associated Press. After coming to California in 1935, Kelley established a photography studio in Hollywood and produced promotional photographs of motion picture stars. David O. Selznick and Samuel Goldwyn retained Kelley to take promotional photos of their stars and starlets for magazine covers and advertising.
Some of Kelley's most famous photo subjects have included Gary Cooper, Greta Garbo, James Cagney, Clark Gable, Winston Churchill, Bob Hope, Marlene Dietrich, Joan Crawford, Jack Benny, David Bowie, John F. Kennedy, Dwight D. Eisenhower, Franklin D. Roosevelt and, of course, Marilyn Monroe, with and without clothes.
