Nicholson was born on April 22, 1937 in Neptune, New Jersey. He was raised believing that his grandmother was his mother, and that his mother, June Frances Nicholson, a showgirl, was his older sister. He discovered the truth in 1975 from a Time magazine journalist who was researching a profile on him. His biological father is believed to have been either Donald Furcillo, an Italian-American showman, or Eddie King (Edgar Kirschfeld), born in Latvia and also in showbusiness. Jack's mother's ancestry was Irish, English, as well as German, Scottish, and Welsh.
