Also, their founder, Charles Taze Russell, was into pyramidology..in fact, that is where he arrived at the date 1914. Look up his name on the internet and you will see that he is buried inside a pyramid shaped tomb!
It is good that one look into the history of the JWs, but unfortunately, much that you may find on many websites will mislead you; most JWs, having little knowledge of the history of the Watch Tower in the days of Russell, when presented by many things on websites may be easily deceived by such presentations. Many things have been distorted, misrepresented, quoted out of context, misquoted, etc., all to make things appear other than the actual facts.
Charles Taze Russell actually did not believe in the Jehovah's Witnesses! He preached against such sectarian authoritarianism. Additionally, his main message was almost the opposite of that preached by the JWs, espectially regarding Armageddon, the ransom for all, the parable of the sheep and goats, etc. It is, therefore, incorrect to think that Russel founded that which he did not believe in, and that which he preached against.

Charles Taze Russell believed that the Great Pyramid is God's Stone Witness in Egypt, if that is what is meant he was "into" pyramidology. Many use the expression "into" and use the word pyramidology to make it appear that Russell "into" some form of spiritism, demonic occulitism, astrology etc., when he was not.

Russell, however, did not arrive at the date 1914 from the Great Pyramid, although the Great Pyramid confirms that date. In 1876, Russell accepted Barbour's conclusion that the Gentile Times were to end in 1914 -- Barbour arrived at that date, however, from the Bible; God's Stone Witness only confirms that date. The Biblical study of the Great Pyramid as done by Barbour, Russell, and the Edgars, however, has nothing to do with any kind of demonic spiritism, astrology, occult practices, pyramid power, pyramid incantations, etc. To me, the evidence is overwhelming that the Great Pyramid is indeed God's Stone Witness in Egypt. It is not, however, a matter that Russell tried force others to believe -- Russell, unlike the JW leadership -- allowed others to form their own conclusions without condemning the brother or sister for doing so.

Go to the Rosemont Cemetery in Pittsburg, and you will see that Russell is NOT buried in a pyramid shaped tomb. Rutherford did have a pyramid monument built several years after Russell died, but that monument is not a tomb. No one is buried there. Nevertheless, it is not the fact that Russell is not buried in that monument that is important. What is important is that those who make such statements are (1) misrepresenting the facts to serve further misrpresentation by (2) implying something sinister by means of their false claim that Russell is buried in or under a pyramid. The most I could say that could possibly be wrong about that monument is that was an extravagant use of funds that could possibly have been used to better advantage, if the funds had been actually used to further the glad tidings of great joy.
Here, however, is a picture of Russell's grave:
The most I could find that would possibly be wrong about the gravestone is that Russell never claimed to be the Laodicean Messenger -- that claim was made by Rutherford and others.
