In 1944, DDT seemed like a great idea. The U.S. Army made this film extolling the virtues of the stuff, “DDT: Weapon Against Disease.” It runs just over 14 and a half minutes, from the Army Signal Corps.
The film recently found its way to the Internet Archives; I assume this YouTube version comes from there (I can’t embed the Internet Archives version).
Though the film does not discuss the dangers of DDT in any appreciable way, it’s a valuable contribution to the historical canon, simply to show what DDT advocates hoped the substance could do, near the end of World War II.
A transcript of the film is available at the National Library of Medicine on-line version.
