California Institute of Technology
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



For the first time the Caltech Archives is making available online an entire multi-media collection.

A Caltech alumnus (MS physics, 1948; PhD aeronautics, 1952), Paul MacCready was a visionary, an inventor and an entrepreneur who pioneered alternative energy solutions through his company, AeroVironment. In the 1970s he began work on the celebrated human-powered Gossamer aircraft series, beginning with the Gossamer Condor. He continued to work on the problems of solar-powered flight and unmanned aircraft, but his interest in environmentally friendly technology also led him to innovative electric and hybrid automotive vehicles, micro-air vehicles and the high altitude, long endurance Helios solar aircraft for telecommunications, imaging and scientific research.

The collection includes a diverse array of documents, media, and objects—manuscripts and printed material; awards; videos and film; photographs and slides, diaries and notebooks; memorabilia, biographical material and ephemera—all created over a span of over 70 years (ca. 1930-2002). It is very fitting with Paul MacCready's innovative and entrepreneurial personality that his collection is the first one to be accessible on the internet in its entirety. 

The project was made possible by a generous gift from the MacCready family. -MS
