Pare Lorentz (December 11, 1905 – March 4, 1992) was an American filmmaker known for his film work about the New Deal. Born Leonard MacTaggart Lorentz in Clarksburg, West Virginia he was educated at Buckhannon High School, West Virginia Wesleyan College, and West Virginia University. As a young film critic in both New York City and Hollywood, Lorentz spoke out against censorship in the film industry.

As the most influential documentary filmmaker of the Great Depression, Lorentz was the leading American advocate for government-sponsored documentary films. His service as a filmmaker for the U.S. Army Air Corps during World War II was formidable, including technical films, documentation of bombing raids, and synthesizing raw footage of Nazi atrocities for an educational film on the Nuremberg Trials. Nonetheless, Lorentz perennially will be known best as "FDR′s filmmaker."
