Exhibit Rooms

The Beckman Room
The Beckman Room is currently closed for renovation.

A new exhibition Becoming Caltech, Building a Research Community, 1910-1930 will open on Monday, February 10, 2020. More information and opening hours will be posted in the next year.



In the lobby of the Beckman Institute, two cases are displaying the Caltech legacy of Arnold O. Beckman (1900-2004), chairman of the Board of Trustees, 1964-1974, and Caltech alumnus (PhD, chemistry, 1928).


The Reading Room
Currently on display is "The Year 1900: Looking Back from the Millennium," a display of photos and artifacts from Caltech's predecessor institution, Throop (pronounced T-R-O-O-P) Polytechnic Institute.

A prior Reading Room exhibit "Scientific Instruments Ancient and Modern" may be viewed online.
