I've checked the Wiki, and couldn't find any mention of accredited scientists (of the era)
who were actually involved in the formation of and/or operations of the Society. The only
mention, by name, of anybody connected with it was Samuel Birley Rowbotham who was
merely a preacher, and who had no scientific qualifications, despite falsely styling himself
as
Dr. Rowbotham.
In fact, Rowbotham's original FE map from around 1860 still forms the basis of current FE
maps—with virtually no amendments since that time, despite massive advances in the
sciences, with a commensurate understanding of the Earth's exact geometry and its relation
to the sun and the rest of our solar system.

So my question is: Apart from the dubious Rowbotham, what were the names of its other
board and/or governing members? Likewise, who formed the board of its 1956 iteration, the
International Flat Earth Research Society? Were its founders, William Shenton and William
Mills technologists—of any profession. Or just fanciful dreamers?
And why was the Universal Zetetic Society so shrouded in mystery?
