Behind-the-scenes information

Bill Nye (born William Sanford Nye on November 27, 1955 in Washington, D.C.) is a science educator and television personality, most famous for his television show Bill Nye the Science Guy (1993-98).


Bill Nye made his first on-screen appearance in the closing live-action segments of Back to the Future: The Animated Series (1991-92), performing science experiments in the video encyclopedia files that viewers could try for themselves at home using everyday objects and/or substances, while Christopher Lloyd as Dr. Emmett Brown explained the principle in narration. Nye normally never spoke while carrying out the experiments, though he did have a single line in one episode of the show.

These segments would eventually lead to Nye getting his own science show, Bill Nye the Science Guy, in 1993, in which he retained the lab coat and bow tie he had worn for Back to the Future: The Animated Series.

In 2013, Nye appeared as himself in an episode of The Big Bang Theory, "The Proton Displacement", as a new friend of Sheldon Cooper, only to later file a restraining order on him. He reappeared in the 2018 episode "The Conjugal Configuration" briefly answering a prank call from Neil deGrasse Tyson.

Nye voiced himself in the 2020 Scooby Doo and Guess Who? episode "Space Station Scooby". The episode and series as a whole includes Frank Welker as Fred Jones and Scooby Doo.
