Out of My Later Years.

First edition of Einstein's collection of social science-related articles, addresses and speeches. Octavo, original cloth, frontispiece of Einstein. Association copy, inscribed by the author in the year of publication on the front free endpaper, "Estella mit herzlichen Grussen A. Einstein. 50." The recipient, Estella Katzenellenbogen was Einstein's former lover in the 1920s. The pair were often seen attending concerts together, and she was known to have visited Einstein at his summer housed in Caputh.  She was best known as a major collector of East Asian art as well as German and French Impressionism and Expressionism. Although baptized as a Protestant, her Jewish ancestry compelled her to flee Germany, first to Switzerland in 1936 and then to the United States in 1939. She settled in Los Angeles where she ran a branch of the Nierendorf Gallery for a brief time in mid 1940s. As this piece attests, Einstein remained in contact with her following her emigration to the United States. Near fine in a very good dust jacket. An exceptional association.
