The Exposition Universelle, held from April to November 1867 in Paris on the Champ de Mars, was attended by about 9 million people, including the Russian emperor Alexander II. The exhibition featured many technical innovations that testified to the new use of electricity - Hugues telegraph apparatus, electric headlights, underwater cable. A hydraulic elevator, ball bearings, a mechanical dough mixer and more advanced agricultural tools were also demonstrated.
