Physicist Stephen Hawking, known for his pioneering brilliance, died today at the age of 76. He is best known for his work on black holes and theoretical physics, but he also made many pop cultural appearances in films, TV shows, books, and comics. Hawking has been referenced and made direct appearances in shows like The Simpsons, Futurama, and The Big Bang Theory as well as the X-Men comics, Star Trek: The Next Generation, and Doctor Who.

Most famously, Hawking made multiple appearances in The Simpsons. In one scene in the season 10 episode “They Saved Lisa’s Brain,” Homer has a beer with Hawking at Moe’s Tavern. “Your theory of a donut-shaped universe is intriguing, Homer,” Hawking quips. “I may have to steal it.” He was featured in an MC battle with the band Flight of the Conchords in another episode, complete with an E=mc2 neck chain. Hawking has called The Simpsons “the best thing on American television,” stating that “almost as many people know me through The Simpsons as through my science.”
