Sam Simon, who made a fortune as co-creator of The Simpsons
, is enjoying giving away untold millions as he battles terminal colon cancer.
The nine-time Emmy-winning writer-producer, 58, says he is using his wealth to, among other causes, help shut down roadside zoos and abusive animal shows, fund a dog-rescue haven in Malibu, and fight hunger, he tells the Hollywood Reporter
"I get pleasure from it. I love it. I don't feel like it is an obligation," says Simon, who more than 20 years ago co-created the animated FOX phenomenon
with cartoonist Matt Groening.
"There is stuff happening, really good stuff, every week," says the upbeat Simon, who has had surgery and is currently undergoing chemotherapy.
A Stanford graduate raised in privilege in Beverly Hills, Simon, who is currently not married and has no children, was given a three- to six-month prognosis in May. He said his own family is fully taken care of, so now he's getting joy in his final days seeing his fortune – tens of millions annually in royalties alone – go to good use.
His Sam Simon Foundation in Malibu is worth $23 million, and other charities, like PETA, Save the Children and the Sea Shepherd Conservation Society, have also been recipients of his largesse.
"I want medical experiments on animals stopped. They don't do anything, and they don't work," Simon said of his future wishes. "Veganism is an answer for almost every problem facing the world in terms of hunger and climate change."
