Jules Gabriel Verne (February 9, 1829 - March 24, 1905) was a French author who was among the first pioneers of the science fiction genre (along with H.G. Wells) He's best known for many of his stories which had been adapted by Disney to become films: In Search of the Castaways, Around the World in 80 Days, and most famously (because it's one of Walt Disney's masterpieces), 20,000 Leagues Under the Sea. In addition, his character Captain Nemo appeared in Once Upon A Time.
He is a main character in the former attraction The Timekeeper, where he discovers that all of the things he wrote about in his books have become possible. He was portrayed by Michel Piccoli.
He was also mentioned by Quorra in the 2010 science fiction sequel to Tron, Tron: Legacy.
