[ Autographs ] ALBERT EINSTEIN (1879 - 1955) American physicist whoseTheory of Relativity and studies of mass and energy relationships revolutionized the field of physics. Inscription in German on a small slip to Rev. Cornelius Greenway, signed "A. Einstein 1930" matted and framed in a simple wood frame with a fine, informal photograph of Einstein on the deck of the S.S. Buny of Hamburg. Very good.
