Louis Leon Pajot, Comte d’ Ons-en-Bray, was a 17th and 18th century personality, not unlike Sloane. He is listed as being a watchmaker, a philosopher, a researcher, a physicist, a chemist, a mathematician, a meteorologist, an astronomer, a naturalist, a botanist, a pteacher, a collector and a mechanical enthusiast.
He had gathered remarkable collections, a cabinet of curiosities that was visited by Peter the Great, Tsar and Emperor of Russia . It is said that during the 18 th century the greatest sovereigns of Europe and the Arab countries crowded Pajot’s home to admire its collections and attend demonstrations.
He also created an anemometer, a device used to measure the wind speed, meaning Pajot created the oldest scientific instrument known to have a data recording system.
