From 1870 to 1900, over a half million Russian Jews came to the United States. Russian Jewish emigration had ceased by the 1920s due to the effects of the First World War, the Bolshevik Revolution, and the Quota Acts, but a century later, Jews from the former Soviet Union began to emigrate in large numbers. This detailed account describes the motivations of Russian and Soviet Jews for leaving their homeland and their subsequent adjustments to life in the United States. Simon, a sociologist, provides insight into who these Jewish immigrants were and are, what they accomplished, and how they have been viewed.
