William Sanford Nye (born November 27, 1955), popularly known as Bill Nye the Science Guy, is an American science communicator, television presenter, and mechanical engineer. He is best known as the host of the PBS and syndicated children's science show Bill Nye the Science Guy (1993–1998), the Netflix show Bill Nye Saves the World (2017–2018), and for his many subsequent appearances in popular media as a science educator.
Born in Washington, D.C., Nye began his career as a mechanical engineer for Boeing Corporation in Seattle, where he invented a hydraulic resonance suppressor tube used on 747 airplanes. In 1986, Nye left Boeing to pursue comedy, writing and performing jokes and bits for the local sketch television show Almost Live!, where he regularly conducted wacky science experiments. Nye aspired to become the next Mr. Wizard, and with the help of several producers, successfully pitched the children's television program Bill Nye the Science Guy to KCTS-TV, Seattle's public television station. 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.
Following the success of his show, Nye continued to advocate for science, becoming the CEO of the Planetary Society and helping develop sundials for the Mars Exploration Rover missions. 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, he debuted the Netflix series Bill Nye Saves the World.
