Jesse Ramsden (Salterhebble 1735 - Brighton 1800), English optician, precision instrument maker, built an electrostatic generating machine with a glass disc. The disc was pressed between 4 leather cushions stuffed with crinolin, and turns between 2 brass horse-show shaped brass tubes that have a comb of metal teeth.
