Einstein Papers Project


Albert Einstein (1879–1955), one of the foremost scientists and public figures of the 20th century, revolutionized our views of time and space, matter and light, gravitation and the universe.

The Einstein Papers Project is engaged in one of the most ambitious scholarly publishing ventures undertaken in the history of science. The Collected Papers of Albert Einstein provides the first complete picture of Einstein’s massive written legacy.

NEH Grant

On August 15, the National Endowment for the Humanities awarded the Einstein Papers Project at Caltech a $300,000 outright award in its scholarly editions and translations program. The grant will support the preparation for print publication of volumes 17, 18, and 19 of the writings, lectures, and letters of Einstein for the period 1930–1933, which includes Einstein’s three visits to Caltech.

In the wee hours of Friday, May 26, the Einstein Papers Project was transformed into a Ditch Day activity site. How to Train Your Dragon was the inspirational source for the puzzle students needed to crack in our conference room. For a brief while our Hermann Landshoff portraits of Einstein were obscured by dragon wings and our library shelves bore mythical captioning rather than scientific or historical guidewords. We've returned to our usual working conditions. It was fun while it lasted! Read more about Ditch Day 2023, by clicking here.
