1900 Paris Exposition was a world’s fair held in Paris, France, from 14 April to 12 November 1900, to celebrate the achievements of the past century and to accelerate development into the next. The fair, visited by nearly 50 million, displayed many technological innovations, including the Grande Roue de Paris Ferris wheel, the moving sidewalk, diesel engines, talking films, escalators, and the telegraphone (the first magnetic audio recorder). It also brought international attention to the Art Nouveau style.
