George Berger was the Commissioner General. Aside from the provision of the building by the French government, the exhibition was privately financed. Organizers would donate profits to scientific works in the public interest.

Adolphe Cochery, Minister of Posts and Telegraphs of the time, had initially suggested that an international exposition should be held.

Among the exhibits were:
  • Apparatus for production and transmission of electricity,
  • natural and artificial magnets, and compasses,
  • devices used in the study of electricity,
  • many applications of electricity (sound, heat, light, electroplating, electrochemistry, signage, power,industrial applications, agricultural and domestic),
  • lightning,
  • old instruments in connection with electricity.


Electric lighting was one of key developments on display at the exposition, with up to 2500 electric lamps in use. Comparative testing of Edison, Swan, Maxim, and Lane-Fox incandescent lamps
