Hi, Shepherd Book and welcome to JWD.
As has been mentioned above, all WTS publications are now being published anonymously. Evidently the reason for this is a need for the WTS to display "modesty" and the lack of wanting to gain the spotlight. This seems rich, seeing that it is coming from a bunch of self-serving arrogant lunatics obsessed with the notion of exclusive divine sanction. The more plausible reason appears to be to make research into WT "scholarship" impossible, thus avoiding accontability and public scrutiny.
Up to 1942, all WT books were published with an author's name, usually the head honcho of the time, either Russell, or Rutherford. Since 1942, with the publication of the book "The New World" - which purported to be a commentary on the book of Job - the policy changed and it was published anonymously, this policy has remained ever since. It is evident, however, that since he was considered, by the WTS at least, to be God's "oracle" on earth, most of the books published between 1942 - 1969 were written by Fred Franz, the 4th WT president.
Ray Franz, his nephew, and one intimately connected with the inner workings of the WTS since he was a former member of the inner sanctum called the Governing Body, informs us, in his book "Crisis of Conscience" pg 61, that his uncle authored the book "Life Everlasting in the Freedom of the Sons of God" published in 1966. Other defectors from behind the WTS "iron curtain" have revealed that Franz also wrote the excreable "Babylon the Great has Fallen" published in 1963.
Several web sites reveal the names of the New World Translation "committee". This WTS slanted Bible "translation" was essentially the work of Freddy Franz who was "largely self-taught" in Bible languages. He was assisted by a committee comprising: Milton Henschel, Nathan Knorr, Hayden Covington, George Gangas, Albert Schroeder, and Grant Suiter. As to how these looney toon characters could be of any "assistance" to Franz is a mystery more obtuse than the Trinity, since none of them could tell a Greek Alpha from a leg of pork. Far from being Greek scholars, they could be best described as geek scholars!
Since 1970, WTS books have been written by groups of writers rather than a single author. A twenty man [''person'' actually, since we know of at least one woman, Barbara Anderson in this group] "writing department" under the oversight of Karl Adams now produces all the WTS literature.
In his book mentioned earlier, on pg 22, Ray Franz reveals the authors of the "Aid" book, published in a complete edition in 1971 [there was an earlier, incomplete edition released in 1970] These were: Ray Franz, Ed Dunlap, Lyman Swingle, Rheinhardt Lengtat, and John Wischuk.
Dunlap later wrote the "Commentary on James" released in 1979.
Ray Franz also tells us that he, along with Karl Adams and Ed Dunlap also wrote the manual "Organisation for Kingdom-Preaching and Disciple-Making" a sort of church instruction brochure oulining the various tiresome WTS procedures for doing just about anything.
Interestingly, Franz also points out that this "Writing Department" no longer has any of the "anointed" counted among its ranks. Which therefore means that the idea of the "anointed" providing the "food at the proper time" is nothing more than a polite fiction. All the writers who pen the WTS publications are mostly young turks who profess to be of the "Other Sheep" and appear to be more familiar with the nuances of the legal profession, rather than the Bible. Many of the "anointed" have often professed total surprise at any "new truth" devised by these new writers, rather than supposedly being the originators of this "food". A question of the "tail" wagging the dog, perchance. To the WTS, perception is more important than reality, and as long as the perception is maintained that all the "Food at the proper time" is coming from the "anointed" no explanations to the rank-and-file seems necessary. [ See Ray Franz's book" In Search of Christian Freedom" pgs 154 -164]
There is a web site maintained by a former Bethel supervisor, Randy Watters, called "Free Minds". Scrolling through there will provide you with the names of the current Writing Department members.
Hope this helps
Cheers
