Albert Einstein (1879–1955) was born in Germany and became an American citizen in 1940. A world-famous theoretical physicist, he was awarded the 1921 Nobel Prize for Physics and is renowned for his Theory of Relativity. In addition to his scientific work, Einstein was an influential humanist who spoke widely about politics, ethics, and social causes. After leaving Europe, Einstein taught at Princeton University. His theories were instrumental in shaping the atomic age.

Alice Calaprice was born in Berlin, Germany, in 1941 to a German father and an Armenian mother. She immigrated to San Francisco with her mother and sister in 1951, and is a graduate of the University of California at Berkeley. After moving to Princeton, NJ, in 1970 with her physicist husband and young children, she went to work at the Einstein Archive in 1978 at the Institute for Advanced Study. She later moved to the Princeton University Press offices and specialized in editing science and math manuscripts. She copyedited all fourteen currently published volumes of the Collected Papers of Albert Einstein and the accompanying English-translation volumes. During this time, she has written and published a number of Einstein books herself. While Senior Editor and administrator of the Einstein Translation Project at PUP, she received a National Science Foundation grant from the History of Science division as well as the Literary Market Place's award for individual editorial achievement in scholarly publishing for 1995. An avid traveler to the most remote corners of the world, she is now retired and lives in southern California. Her most recent book, AN EINSTEIN ENCYCLOPEDIA, co-authored with Daniel Kennefick and Robert Schulmann, will be published by Princeton University Press in October 2015.
