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–present), and for his many subsequent appearances in popular media as a science educator.

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 would regularly conduct wacky science experiments.
