Caltech Archives and Special Collections
The California Institute of Technology Archives and Special Collections, founded in 1968, has a mission of facilitating understanding of Caltech’s role in the history of science and technology. Our collections include the papers of Caltech researchers; photographs, film, audio, video, websites, and publications documenting Caltech’s history; scientific instruments characteristic of research at Caltech; and rare books anchored by the Rocco Collection of early modern physics and astronomy. We have been collecting oral histories of Caltech faculty and other affiliates since 1979, and have published approximately 200 transcripts on the web. Caltech has also made publicly available on the web the papers of astrophysicist George Ellery Hale, founder of Mount Wilson Observatory; aeronautical engineer and pioneer of human-powered flight Paul MacCready; and Nobel Prize-winning particle physicist and molecular biologist Donald Glaser.
