Spielberg was born in Cincinnati, Ohio, to an Orthodox Jewish family. His mother, Leah Posner (later Adler) (January 12, 1920 – February 21, 2017), was a restaurateur and concert pianist, and his father, Arnold Spielberg (born 1917), was an electrical engineer involved in the development of computers. His paternal grandparents were emigrants from Ukraine who settled in Cincinnati in the first decade of the 1900s. In 1950, his family moved to Haddon Township, New Jersey, when his father took a job with RCA. Three years later, the family moved to Phoenix, Arizona. Spielberg attended Hebrew school from 1953 to 1957, in classes taught by Rabbi Albert L. Lewis.
