Greetings Done4Good,
Randy Watters wrote an article in The Free Minds Journal awhile back on the credibility of THE FOUR PRESIDENTS. I will see if I can locate the issue and provide you more information. The book has Edmond C. Gruss as its editor and "author" as the author, in "hiding" to avoid "a malice unheard of in the Christian community" upon him, family and friends. [ibid., p. ix.]
"Author," forty years a JW, was a member of the Brooklyn administrative staff and knew Knorr, Franz [Fred], Henschel, Covington, Macmillan and many of the GB. Upon leaving Bethel, "author" was offered a position as a DO, which he declined.
I will return; I appreciate your patience..
