Bonetti Type Electrostatic Machine

A rare Bonetti-type electrostatic machine, attributed to the Bonetti firm (Paris), circa 1895–1905.A large laboratory or educational model, featuring two ebonite discs (55 cm in diameter) mounted on an elegant openwork cast-iron frame, complete with nickel-plated columns and adjustable electrodes. Base length: 68 cm. Total height: 77 cm.This machine exhibits the characteristics of late 19th-century Wimshurst-Bonetti models—devices developed to generate static electricity for use in physics laboratories, university faculties, and early electrotherapy and radiology clinics.The absence of metal sectors on the discs is consistent with Bonetti models, which differ from standard Wimshurst machines through this specific design utilizing ebonite discs.A superbly crafted machine, retaining its original frame, hand crank, neutralizing bars, and electrodes. Although the manufacturer's plate is missing—precluding a definitive attribution—the unit closely resembles Parisian-made instruments from the late 19th century.A rare collector's item, ideal for enthusiasts of antique scientific instruments, physics, or the history of radiology.
