Elliott O'Donnell was an Irish author known primarily for his books about ghosts. He claimed decent from Irish chieftains of ancient times, including Niall of the Nine Hostages (the King Arthur of Irish folklore) and Red Hugh, who fought the English in the sixteenth century. O'Donnell was educated at Clifton College, England, and Queen's Service Academy, Dublin, Ireland. As he became known as an authority on the supernatural, he was called upon as a ghost hunter. He also lectured and broadcast, via radio and television, on the paranormal in Britain and the United States. In addition to his more than 50 books, he wrote scores of articles and stories for national newspapers and magazines. O'Donnell claimed, "I have investigated, sometimes alone, and sometimes with other people and the press, many cases of reputed hauntings. I believe in ghosts but am not a spiritualist."
