California Institute of Technology
Welcome to the Caltech Archives


The Caltech Archives
was formally established in 1968 to serve as the collective memory of the California Institute of Technology. Our mission is to preserve and make accessible the institutional records, personal papers, documents, artifacts and pictorial materials that tell the school's history.

The Archives' unique research collections in the history of science and technology range from the time of Copernicus to today. They are available to the campus community for instructional and research purposes, as well as to qualified non-campus users by appointment.
