Cadet, Jean-Marcel (L)
Jean-Marcel Cadet (1751-1835) was French mineralogist, who was Inspector of Mines on Corsica for 25 years. He wrote a number of papers and books on the geology of the island. Included in his output was Memoire sur les jaspes et autres pierres precieuses de l’isle de Corse(a), published in 1785, in which he also reviewed Plato’s account of Atlantis in his Critias and Timaeus and concluded that Atlantis had been situated in the Atlantic.
My previous entry under the name of Louis Claude Cadet de Gassicourt was completely incorrect, for which I apologise.
