Louis de Rochemont (January 13, 1899 – December 23, 1978) was an American film maker known for creating, along with Roy E. Larsen from Time, Inc., the monthly theatrically shown newsreels The March of Time. His brother Richard de Rochemont was also a producer and writer on The March of Time.
The newsreels defined film news from 1935 to 1951. The 20-minute films, which combined filmed news with interpretive interviews and dramatizations, appeared between featured films in theaters.
When he moved from newsreels to feature films, de Rochemont chose to produce films based on real stories in actual locations, often with locals in the cast. After three spy films that helped define film noir, including The House on 92nd Street (1945), he produced a wide array of feature films such as the semi-documentary Boomerang (1947). He has been called the "father of the docu-drama." His early documentary productions won two Academy Awards. He also produced Windjammer (1958) and The Roman Spring of Mrs. Stone (1962).
