John A. Keel (1930-2009), was an American journalist and influential UFOlogist best known as the author of 'The Mothman Prophecies'. In the 1950s, he spent time in Egypt, India, and the Himalayas investigating snake charming cults, the Indian rope trick, and the legendary Yeti, an adventure that culminated in the publication of his first book, 'Jadoo'. A very rare book.
