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.

Riesenfeld Family Visits the EPP

Riesenfelds in EPP conference room

The Einstein Papers Project were delighted to receive a visit from members of the Riesenfeld family earlier this week. As noted in the Spring 2019 issue of Techniques, Caltech received $50,000 for the Einstein Papers Project and $50,000 for the Palomar Observatory from the estate of Shoshana Riesenfeld.

We are truly grateful for the support.
