In 1946, Dr. David P. Boder, a psychology professor from Chicago's Illinois Institute of Technology, traveled to Europe to record the stories of Holocaust survivors in their own words.

Over a period of three months, he visited refugee camps in France, Switzerland, Italy, and Germany, carrying a wire recorder and 200 spools of steel wire, upon which he was able to record over 90 hours of first-hand testimony. These recordings represent the earliest known oral histories of the Holocaust, which are available through this online archive.
