Ignacio Herbert "Nacio Herb" Brown was an American writer of popular songs, movie scores and Broadway theatre music in the 1920s through the early 1950s. Amongst his most enduring work is the score for the 1952 musical film Singin' in the Rain.

Singin' in the Rain is a 1952 American musical romantic comedy film directed and choreographed by Gene Kelly and Stanley Donen, starring Kelly, Donald O'Connor, and Debbie Reynolds and featuring Jean Hagen, Millard Mitchell and Cyd Charisse. It offers a lighthearted depiction of Hollywood in the late 1920s, with the three stars portraying performers caught up in the transition from silent films to "talkies".
