Who is Alfred montapert?

Alfred Armand Montapert wrote the book The Supreme Philosophy of Man: The Laws of Life. It is an amazing book, written in 1970. It's basically the same philosophy of The Secret, even better. I only know he was in Los Angeles at the time he wrote it and I haven't been able to find anything else about him either! The book is now out of print and the only place I can find it is on Amazon and it's going for over $100+ for the paperback.
