Lewis David Einstein (March 15, 1877 in New York City - December 4, 1967 in Paris, France) was an American diplomat and historian.
The son of wool magnate David L. Einstein, Lewis Einstein had two sisters: Amy, who married Joel Elias Spingarn, and Florence, who married Sir Charles Waldstein. He graduated from Columbia University in 1898, and earned a master's degree in 1899.[1]
Einstein's diplomatic career began in 1903, when he was appointed as Third Secretary of Legation at Constantinople.[2] The next year, he married Helen Ralli, a noted English beauty a number of years older than he, whose sister was married to the younger son of Francis Stonor, 4th Baron Camoys.[1] This marriage led to friction between Einstein and his father, who worried that Ralli would damage the younger Einstein's career; Ralli was twice a divorcee, and divorced women could not be received in some European courts.[1]
Einsten advanced from Second Secretary to First Secretary and then Charge d'Affairs during the Young Turk Revolution of 1908, remaining in Constantinople despite the hostilities.[3] He served as United States Ambassador to Costa Rica for one month in 1911, before his wife's ill health in the country's high altitude forced him to leave the post.[4] In 1921, Warren Harding made him United States Ambassador to Czechoslovakia[5], a position he held until 1930. He was also a member of the Council on Foreign Relations.
Lewis Einstein was disinherited by his father after marrying Ralli, except for a sum of $125,000 .[3] After Einstein's death, newspapers reported that a $1,250,000 share of the elder Einstein's estate, valued in total at approximately $4,000,000[6], had been set aside for Lewis Einstein in the event that he divorced his wife, and that it passed to his sister Lady Waldstein after he declined to do so.[1] This report was denied by Lady Waldstein, who indicated that the father's only wish regarding Lewis Einstein was to see that he was "taken care of", a means she accomplished by granting him an annual allowance of $20,000.[6] Earlier, Lewis had received nothing from the estate of his mother Caroline Einstein, who instead divided her property among Einstein's sisters and various friends among European nobility.[7]
Einstein wrote the following books:
Einstein also engaged in a longtime correspondence with Oliver Wendell Holmes, Jr., and in 1964 their collected letters were published in the volume The Holmes-Einstein Letters : Correspondence of Mr. Justice Holmes and Lewis Einstein 1903-1935, edited by James Bishop Peabody.
