David Graves was a historian and published author, interested in fringe history. He wrote a series of books, on subjects such as Atlantis, the miracles of Fatima, the Nazca Lines, and how they could affect the modern world. During the very first adventure of the Justice League, David, his wife Jennifer, and his two children, Jason and Emma, came under attack by Darkseid's forces. Accepting what he believed to be his fate, and covering his children's eyes for their inevitable death, Graves and his family are saved by the superheroes that would eventually become the Justice League.
