First edition, first issue, in the rare author's offprint form with a newly set title-page. One of Einstein's last important scientific works, this publication of the unified field-theory caused quite a sensation. It was the first separate printing of one of a series of five papers published between 1925 and 1929 in which Einstein attempted to develop a unified field theory, reconciling in a single formula the laws of electromagnetism and gravitation.
