I agree Biahi. Charles T Russell was a religious fanatic carrying on making money from all of his questionable business activities including Zion's Watchtower and Herald of Christ's Presence.
He set a template for subsequent presidents and leaders of the religion he started including:
Sound finances first
Date fixations and gross disappointments of those dates
Useless moving the goal posts forward in time
Crazy marriages of the presidents
The idea, whether denied or otherwise, that the WT leadership were God's exclusive channel.
Each of the presidents were fixated on the end of the world with all doctrines fed into this primary belief. A belief which made money! Why kill the goose which lays golden eggs?
Russell had a celibate marriage, it looks like Rutherford left his wife and son and lived with one of his two diet advisers! Knorr's wife appears to have let it be known in Bethel that she was frustrated in her sex life and Fred Franz was clearly married to his apocalyptic delusions.
Russell made a lot of money as did Rutherford but keeping the org on the rails involved mind manipulation and a loyal flock groomed to believe the certainties of the president and later the governing body. Russell though got the attention through his effective use of media and wide syndication of his sermons.
So Russell was a preacher, with misleading and wrong information of course-- and his successors, climbing onto his bandwagon were cashing in on Russell's flawed success.
If God had an organisation would it constantly be forced to evolve like the JW org has?
