David O. Selznick (1902-1965) was an American film producer.  He began his Hollywood career in 1926, as an assistant story editor at Metro-Goldwyn-Mayer.  He left MGM for Paramount Pictures in 1928.  In 1931 he joined RKO as Head of Production. In 1933 he returned to MGM.  His father-in-law, MGM CEO L.B. Mayer, established a prestige production unit specifically for Selznick.

Despite enjoying great success with MGM, Selznick left in 1935 to establish his own studio, Selznick International Pictures, which distributed its films through United Artists.  He is best known for producing Gone with the Wind (1939) and Rebecca (1940); both won Oscars for Best Picture.
