Few JWs, in the years leading up to 1975, seemed to know anything about "Judge" Rutherford's utterances concerning 1925.
As an example, forty years ago in the small town where I started associating with the JWs, they had become such a pest that the local churches all got together and printed an information circular - giving the Witnesses the proverbial "both barrels".
One of the things that this circular dug up was the WTS's repeated failure of prophecy; and it did mention 1925 as being one such case of several.
The "brother" I was "studying" with at that time strenuously assured me that the WTS had never ever, at any timementioned anything about 1925. (Like the local churches were having to invent stuff, in order to smear the JWs!) Furthermore, I think that he sincerely believed this to be the case - so well had the 1925 debacle been covered up by then.
As another poster put it - " when you fail to know your history, you are doomed to repeat it."
Thank God for the Internet!
