The Athenaeum is a well-kept secret amongst alumni and friends of the California Institute of Technology. Membership is open to individuals associated with the teaching, research, or administrative staffs at Caltech, the Jet Propulsion Laboratory, the Huntington Library and Art Gallery, and the Palomar Observatory.

As early as 1921, George Ellery Hale, renowned astronomer, Caltech trustee, and director of the Mount Wilson Observatory, envisioned an Athenaeum in Pasadena modeled after the club in London. Hale had already spurred intellectual life in the region by bringing former MIT President Arthur A. Noyes and physicist Robert A. Millikan to Caltech. Together this trio positioned the California Institute of Technology as a world-class center for teaching and research in engineering and science. During the 1920s, cultural life also blossomed around two other centers of scholarship in Southern California–the Mount Wilson Observatory and the Huntington Library and Art Gallery.

The first formal dinner was held in February 1931, when Albert Einstein arrived for a two-month sojourn at Caltech. Three Nobel Prize winners, Albert Einstein, Robert A. Millikan, and A. A. Michelson, attended that dinner. Portraits of Hale, Noyes, Millikan, the Balches, and Caltech’s past presidents hang in various rooms throughout The Athenaeum.

The Athenaeum’s dining facilities are open Monday through Friday,
except Institute holidays.
