Sheldon Adelson — business (las vegas) with roots in the Russian Empire

His father Arthur Adelson was a taxi driver who had emigrated from Lithuania (Russian Empire) and his mother's family had Ukrainian Jewish roots. Adelson grew up in poverty in Dorchester, Boston, and built his fortune from nothing — the immigrant's child who became a billionaire through sheer persistence. His Las Vegas Sands empire was built on the same gambling industry that Russian-Jewish immigrants had pioneered from the beginning.
