Einstein's Archive Now Available Online

The archive is the result of more than two decades of collecting and researching. Einstein left a collection of 40,000 personal papers when he died in 1955; since 1986, 40,000 more documents have been collected—most of them by the EPP staff—says Diana Kormos-Buchwald, professor of history at Caltech and director of the EPP.

One of the archive's highlights is a handwritten manuscript for a 1946 article entitled "E=mc²: On the Most Urgent Problem of Our Time," which was published in the magazine Science Illustrated. Explaining general relativity to a lay reader, the manuscript is one of only three documents in the world containing the famed "E=mc2" formula in Einstein's own handwriting.

The archive is available at www.alberteinstein.info. To view selected documents, including the ones described here, visit http://www.alberteinstein.info/gallery/index.html.
