Features of Associates Membership

As a member of the Caltech Associates, you have intimate opportunities to engage with Caltech faculty, Nobel Prize winners, JPL engineers, and luminaries at the forefront of their disciplines through a wide range of stimulating events and travel opportunities. These events offer close exposure to world-changing discoveries and trends in science, engineering, medicine, and the arts.


Participate in the exclusive Associates Travel Program, designed for the intellectually curious traveler who enjoys unique experiences and often first-class amenities. Each destination is enhanced by a trip leader form the Caltech faculty whose expertise will deepen your understanding of sciences, engineering or technology associated with your locale. We work with premiere travel companies to design expeditions, preparing itineraries that also incorporate the history and culture of each area. This frequently includes behind-the-scenes access to observatories, museums, entertainment and local amenities. Trips vary in length and include everything from day trips to exotic, bucket-list locations. Select Associates are only available to President's Circle members. You can upgrade your membership at any time to access these and other President's Circle opportunities.


Invitations to approximately 20 Associates events and programs each year feature thought-provoking speakers and topics. Reflecting upon our members' busy schedules, diverse events include lunch and dinner programs, behind-the-scenes tours of typically inaccessible labs and clean rooms, and much more. Also on the agenda: conversations and panel discussions of forward-leaning ideas—from the future of driverless cars to early cancer detection, to quantum computing, to various aspects of artificial intelligence.


Be among the first to hear Caltech's breaking news. Whenever possible, VIP seating is reserved for Associates at press conferences, Nobel Prize announcements, and special lectures announcing Caltech's many important discoveries.


Become part of a dynamic intellectual community. With more than 1,750 members, the Caltech Associates program, produced on campus in Pasadena and in New York City; Northern CA, Orange County/San Diego and the Westside, fosters lifelong friendships and a sense of community among those who are life-long learners. All regional programs are open to all Associates.


Your membership dollars seed high-impact and directly benefit scientists and students. Many members choose to deepen their involvement at Caltech, fueling research they feel passionate about. Your tax-deductible membership dollars support the future of science, engineering, and technology.

The Athenaeum

Associates are eligible to become members of the Athenaeum, Caltech's private membership club.

A Longtime Connection

The history of the Athenaeum is closely tied to the Caltech Associates. It was built with funds donated by Allan and Janet Balch, founding members of the Associates, and was conceived as a gathering place—a hearthstone—for the Associates, the faculty, and other members of the Caltech community. Since the Associates' first formal dinner in January 1931—held to honor visiting professor Albert Einstein—the Athenaeum has hosted countless memorable events.

On occasions both formal and informal, the club has welcomed the spirited intellectual community of which the Associates are such an important part. Growing only more beautiful with time and restoration, the Athenaeum continues to be an icon of the enduring partnership between the Associates and the Institute.

Global Opportunities

As a member of the Athenaeum, you also can gain access to other private reciprocal clubs around the globe. All you need is a letter of introduction from the Athenaeum to the reciprocal club stating that you are a member in good standing.
