Charles Taze Russell: His Life and Times: The Man, the Millennium and the Message by Fredrick Zydek is the latest biography on Pastor Russell, and I must say I am very impressed. I have read other historiees on the Pastor Russell by Zydek (all unpublished manuscripts) but this one is far better than the last one authored by Charles Redeker aq few years ago. Zydek is a Catholic.
The author is neither a Bible Student or a Jehovah's Witness. although he grew interested in the Pastor when his aunt converted to the Witnesses and gave him a set of the Millennial Dawn volumes and for the past 30 years Professor Zydek has been researching the Pastor and does an excellent job. I highly recommend it!
