Albert Einstein (1879–1955) was a visiting scientist at Caltech on three separate occasions in the early 1930s. Seventy years later, his presence was officially restored at Caltech in the summer of 2000 through the Einstein Papers Project’s installation on campus.
After Einstein's death in Princeton in 1955, the trustees of his estate, Otto Nathan and Helen Dukas, organized the documents in his home and collected a substantial amount of additional material from all around the world over a period of 25 years. They planned for all of Einstein's papers, personal and scientific, to eventually be published and in 1971 Princeton University Press took on the massive publishing effort.
