Sam Simon, the nine-time Emmy winning co-creator of The Simpsons died Monday at age 59. Simon, who also wrote for Taxi, Cheers, and It’s Garry Shandling’s Show, was diagnosed with terminal colorectal cancer in 2012. He developed The Simpsons with Matt Groening and James L. Brooks in 1989. While he left the show in 1993, he kept an executive producer credit that earned him a fortune. Upon being diagnosed with colon cancer, Simon, an animal lover, began buying zoos and circuses to free animals. In 2014, he announced that he was going to donate his $100 million fortune to multiple charities including PETA, Save the Children, and Feeding Families.
