Mark Cuban's family, of Eastern European Jewish descent. His maternal grandparents were Jewish immigrants from Romania. His parental grandfather, who emigrated from Russia through Ellis Island, and changed his surname from "Chabenisky" to "Cuban", was also Jewish.
Mark Cuban was born on July 31, 1958, in Pittsburgh, Pennsylvania, United States, to Norton and Shirley Cuban. Cuban had a typical middle-class childhood. His father, Norton, spent nearly half a century working at a car upholstery shop. His grandfather, Morris Chobanisky, emigrated from Russia and fed his family by selling merchandise out of the back of a truck.
In 2020, Cuban told that being Jewish made him more empathetic. He said one-quarter of his mother’s family was murdered in the Holocaust and, when his grandparents came to America from Russia, "they didn’t come here because they thought the weather was nice. They came here because if they didn’t leave they’d be dead."
