I too read this book when I was still a JW. At that time my thoughts were that he was quite nationalistic about his German origin and the work of the org in Germany. It is true, as he states in his book that the Germans are experts in organization. I wonder if Nathan Knorr had this ability to organize from German descent. I know that Knorr made clones of some who had German names and probably were of German origin although born in America.
A second point that caught my attention was that he criticized the Watchtower for becoming book publishers and commercializing the distribution of books. Yet Schnell, even while he was a JW became a distributor of books and Bibles and made quite a successful commerce of it.
I have a copy of the book and since this thread has appeared I am re-reading it and when I am finished, I will post any further observations. I find that Schnell gives a lot of his own opinions on events of his era. He claims that Rutherford had a game plan from the beginning regarding all the events that took place. However, I find his book very revealing in spite of his bias. It presents the atmosphere of the Rutherford times.
As to comparing Franz and Schnell?s books, what for? Sour grapes and peaches.
I believe that Schnell spent the remaining part of this life in the Okanogan in British Columbia. I will try to find someone who knows more of his latter days and can fill us in.
