Gusen [War Crimes Commission: Mauthausen Concentration Camp]

United States Navy Lieutenant E. R. Kellogg certifies motion pictures of Nazi concentration camps in an affidavit presented in the "Nazi Concentration Camps" film by the Americans as evidence during the International Military Tribunal at Nuremberg. Kellogg had expertise in motion picture and photographic techniques through his employment with Twentieth Century Fox Studios in California from 1929 to 1941. He attests that he has thoroughly examined the concentration camp liberation films of the Army Signal Corps and found them to be unaltered, genuine, and true copies of the originals in the U.S. Army Signal Corps vaults.

George Stevens (December 18, 1904 – March 8, 1975) was an American film director, producer, screenwriter and cinematographer. During World War II, Stevens joined the U.S. Army Signal Corps and headed a film unit from 1943 to 1946 under General Eisenhower. His unit shot footage documenting D-Day — including the only Allied European Front color film of the war — the liberation of Paris and the meeting of American and Soviet forces at the Elbe River, as well as horrific scenes from the Duben labor camp and the Dachau concentration camp. Stevens also helped prepare the Duben and Dachau footage and other material for presentation during the Nuremberg Trials. In 2008, his footage was entered into the U.S. National Film Registry by the Librarian of Congress as an "essential visual record" of World War II.
