I've heard it stated that the founder of Jehovah's Witnesses, Charles Taze Russel, was a Freemason (33rd Degree) which may have been partially responsible for his interest in collaborating bible prophecy with the pyramids, as well as the symbolism he used in some of his books.
There seems to be arguments both for and against this, both convincing. Is there any solid historical proof of as to whether or not this claim is true?
