Thanks Cedars for putting the time and effort to put this together. The pre-71 photo of the Board of Directors was interesting, I think I remember seeing it before someplace (was it in MacMillen's book Faith on the March?).
The timeline of governing body members is good to have to. I would also like to see, if it is possible to even get the information, a timeline for all the Board of Director members from 1917 to 1971. It would be quite a task to compile, but interesting. While it is fair to say that there was NO governing body before 1971, and all major decisions were made by the President or Vice-president in the Knorr-Franz years, there was a Board of Directors all those years. The Board members, I suspect, were among the more influential individuals at Bethel, even though they did not function as a governing body.
Now, of course, the President, and board members of the legal corporations are not aligned at all with the governing body.
One thing that has always irked me is the way the 7 associates of Rutherford are referred to as the 'seven directors of the Society'. Maybe someone could confirm this, but I don't believe that was true. They were not directors at the time they were sent to prison (maybe later they were made directors, but in 1918 they were not. Especially DeCecca, who was not even at Bethel at the time.)
