Raphael Abramovitch

Raphael Abramovitch Rein (Russian: Рафаил Абрамович Рейн; 21 July 1880 – 11 April 1963) was a Russian socialist, a member of the General Jewish Workers' Union in Lithuania, Poland and Russia (Bund), and a leader of the Menshevik wing of the Russian Social-Democratic Workers' Party (RSDRP).

Abramovitch emigrated from Soviet Russia in 1920, landing in Berlin, where he was a co-founder of the long-running Menshevik journal The Socialist Courier. After 1940, with the rise of fascism in Europe, he made his way to the United States, where he lived his final years.
