Edmund Charles Gruss (c. 1933) is Professor Emeritus at The Master's College in Santa Clarita, California and an author. He researches groups he considers to be "cults" and the occult and has written many books on those subjects especially on the Ouija Board and Jehovah's Witnesses.
Gruss was a member of the Jehovah's Witnesses from the age of seven to seventeen. He subsequently converted to evangelical Christianity after he "found Christ."
This is one of the very best books exposing the JWs.The author goes through their history and their many failed prophesies.1914 was to be the end,no wait 1925,no 1942,or 1945...no wait 1975 for sure! By the I was with this strange religious group back in the '70s.Oh I loved how the writer talks about how the founder of the Witnesses was a real charlatan! Of course only a few JWs would dare read this book.
