Bill Nye, American engineer, educator, and television host
William Sanford Nye (born November 27, 1955), popularly known as Bill Nye the Science Guy, is an American mechanical engineer, science communicator, and television presenter. He is best known as the host of the science television show Bill Nye the Science Guy (1993–1998), the Netflix show Bill Nye Saves the World (2017–2018), and for his many appearances in popular media as a science educator.

Born in Washington, D.C., Nye began his career as a mechanical engineer for Boeing in Seattle, where he invented a hydraulic resonance suppressor tube used on 747 airplanes. In 1986, he left Boeing to pursue comedy—writing and performing for the local sketch television show Almost Live!, where he regularly conducted wacky science experiments.

Aspiring to become the next Mr. Wizard, Nye successfully pitched the children's television program Bill Nye the Science Guy to Seattle's public television station, KCTS-TV. The show—which proudly proclaimed in its theme song that "science rules!"—ran from 1993 to 1998 in national TV syndication. Known for its "high-energy presentation and MTV-paced segments", the program became a hit among kids and adults, was critically acclaimed, and was nominated for 23 Emmy Awards, winning 19, including Outstanding Performer in Children's Programming for Nye himself.

Nye continued to advocate for science, becoming the CEO of The Planetary Society. He has written two bestselling books on science: Undeniable: Evolution and the Science of Creation (2014) and Unstoppable: Harnessing Science to Change the World (2015). He has appeared frequently on other TV shows, including Dancing with the Stars, The Big Bang Theory, and Inside Amy Schumer. He starred in a documentary about his life and science advocacy, Bill Nye: Science Guy, which premiered at the South by Southwest Film Festival in March 2017; and, in October 2017, was named a NYT Critic's Pick. In 2017, the Netflix series Bill Nye Saves the World debuted.
