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.


Published Volumes

Online / On Paper

The Collected Papers of Albert Einstein series now covers Einstein's life and work up to his 46th birthday. It presents, as annotated full text, 400 writings by Einstein and 3,450 letters written by and to him. An additional 2,654 documents appear in abstract.

EPP Heralds Release of Two New Books

imageOur esteemed colleague: A. J. Kox, Senior Editor at the Einstein Papers Project, Visiting Associate in History at Caltech and Emeritus Professor at the University of Amsterdam, has released his latest book with Springer The Scientific Correspondence of H.A. Lorentz. Volume 2, the Dutch Correspondents. A historian of modern physics, Professor Kox is a veteran member of our project, having started his work on The Collected Papers of Albert Einstein in 1985.

This is the second and final volume of Dutch physicist Hendrik Antoon Lorentz’s scientific correspondence with Dutch colleagues, including Pieter Zeeman and Paul Ehrenfest. The 294 letters cover multiple subjects, ranging from pure mathematics to magneto-optics and wave mechanics. They reveal much about their author, including Lorentz's surprisingly active involvement in experimental matters in the first decades of his career.

The book chronicles the lives and intellectual contributions of Ricci and his brilliant student Tullio Levi-Civita, including letters, interviews, memoranda, and other personal and professional papers, to tell the remarkable, little-known story of how two Italian academicians, of widely divergent backgrounds and temperaments, came to provide the indispensable mathematical foundation—today known as the tensor calculus—for general relativity. 8-13-18
