In 1900, William Henry Goodyear traveled with photographer Joseph Hawkes to visit the 1900 World Expo (Exposition Universelle) in Paris. Goodyear was the son of Charles Goodyear, the inventor of rubber vulcanization. Back in New York, he exhibited the images - colorized for better effect - to the American public who could not afford the transatlantic voyage. The Exposition Universelle of 1900 was held in Paris from 15 April to 12 November 1900. The fair, visited by nearly 50 million, displayed numerous inventions new at the time such as diesel engines, sound films, escalators, moving sidewalks and the magnetic audio recorder.
