Celebrities and dignitaries from around the world visited the Exposition. Thomas Edison, with his wife and daughter, visited the Exposition on August 14, 1889, his third day in France, to visit the exhibit where his improved phonograph was being demonstrated. He also ascended to the viewing platform of the Eiffel Tower, where he was met by a group of Sioux Indians who were at the Exposition to perform in Buffalo Bill's Wild West Show. He returned to the Eiffel Tower later in his visit, where he was hosted for a lunch in Eiffel's private apartment on the Tower, along with the composer Charles Gounod.
