Historical Electrostatic Generator - 19th-Century Static Electricity Device #113537 (License: Personal Use)

This black-and-white engraving depicts a late-19th-century electrostatic generator, likely inspired by the Wimshurst or Holtz designs, featuring a rotating glass disc (A), fixed metal brushes or combs (B and C), and a cylindrical Leyden jar (D) for charge storage. The device operates via electrostatic induction, where friction and separation of charges on the disc produce high-voltage static electricity for demonstrations and early electrical research. Its wooden base and brass fittings reflect typical workshop instrumentation of the era.
