Mersenne’s Numbers (R.T. Gould / Fermat)

Found - a fascinating forgotten work Oddities: A Book of Unexplained Facts (Allan, London 1928) by R.T. Gould.

Something of a polymath, he wrote an eclectic series of books on topics ranging from horology to the Loch Ness Monster. He was a member of the Sette of Odd Volumes (Brother Hydrographer) and the book Oddities is dedicated to the club. He was a science educator, giving a series of talks for the BBC's Children's Hour starting in January 1934 under the name "The Stargazer", and these collected talks were later published. He was a member of the BBC radio panel Brains Trust. He umpired tennis matches on the Centre Court at Wimbledon on many occasions during the 1930s.
