4to (178 x 220). 1 leaf (2 pp.). Collection of 34 signatures. Albert Einstein's autograph, confidently penned as "A. Einstein, Berlin", appears among a collection of academic signatures. Following the handwritten title, "Gathering of Harvard men of Berlin on the occasion of congratulating Ambassador Sackett on the degree of Doctor Honoris Causa conferred on him by the University of Tübingen on April 25, 1932", the signatures range from 13 April to 7 May, with Einstein's undated but placed chronologically between April 14th and 16th. 1932 was Einstein's final full year living in Berlin; following the increasing restrictions on Jewish Germans and the seizure of his property, he would emigrate to America in 1933. - The signatures which accompany Einstein's are all of his fellow academics, most of whom are American. Though the American ambassador, Frederic M. Sackett, was himself an alumnus of Harvard Law, Einstein's future lay at the university associated with the name signed after his, a G. Floyd Parker who had graduated from Princeton in 1919. - A clear Einstein autograph in an interesting academic context. Hint of edgewear; signature bright and clean.
