Bill Nye

William Sanford "Bill" Nye was born November 27, 1955 to Jacqueline and Edwin Darby "Ned" Nye, both World War 2 veterans. From 1991 to 1993, he appeared in the live-action educational segments of Back to the Future: The Animated Series in the nonspeaking role of assistant to Dr. Emmett Brown (played by Christopher Lloyd), in which he would demonstrate science while Lloyd explained. Nye's Science Guy personality appears alongside Ellen DeGeneres and Alex Trebek in a video at Ellen's Energy Adventure, an attraction that has been playing since 1996 at the Universe of Energy pavilion inside Epcot at Walt Disney World.
