Unveil more than 100 years of history through stock photography in the prestigious Bettmann Archive. The archive is a compilation of Dr. Otto Bettmann’s life’s work and the United Press International Photo Archive — more than 11 million photographs from the 19th and 20th centuries. One of the most significant historical collections of images in the world, this international treasure is housed in the state-of-the-art Film Preservation Facility (FPF) in Pennsylvania. New scans of images that have never been digitized are uploaded daily.
