Peter Graves was born Peter Duesler Aurness on March 18, 1926, in Minneapolis, Minnesota, the son of Rolf Cirkler Aurness (1894–1982), a businessman, and his wife Ruth (née Duesler, died 1986), a journalist. Graves's ancestry was Norwegian, German, and English. He used the stage name Graves, a maternal family name, to honor his mother's family, and also so as to not be confused with his elder brother James Arness, star of the television series Gunsmoke.
