Alumni Weekend is a celebration for alumni of all class years — undergraduate, graduate, and former postdocs — with opportunities to explore campus, hear from Institute leaders, and take part in programs throughout the weekend.
The first 50 alumni to register will receive a complimentary copy of To Illuminate Nature, from Molecules to the Cosmos: A Narrated History of Caltech Discovery from the 1920s to the 2020s, by David Zierler. Across 595 pages, the book traces a century of discovery across Caltech’s first hundred years, through oral histories of Caltech faculty, staff, Trustees, and alumni, along with historical essays and scientific images. Copies will be available for recipients to pick up during Alumni Weekend.
