Welcome to the Caltech Archives


The Caltech Archives
were 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.

Talk of the Archives

In collaboration with the Einstein Papers Project, the Caltech Archives has mounted an exhibit honoring the centenary of Einstein's publication of the theory of general relativity in 1915. The exhibit may be viewed on the second floor of Parsons-Gates Hall of Administration. The display focuses on Einstein's visits to Caltech in the early 1930s during which he discussed the implications growing out of the theory of relativity with scientists in Pasadena, both at Caltech and at the Mount Wilson Observatory. The California public and press, while understanding little of the science, were lavish in their attention to the world's most famous scientist.
