Jason Bird was a part-Jewish acrobat and vaudeville-nightclub comedian. He was the son of Richard Cordwainer Bird and Millicent Bloom.

Jason Bird married Rhonda Rassendyll, rather against the wishes of her parents, who was closely related to the Earls of Burlesdon. They had one son, the writer and militant foe of evil, Cordwainer Bird. Jason Bird and his family are described in Doc Savage: His Apocalyptic Life.
