Sam Simon, ‘Simpsons’ Co-Creator, Dead at 59

“The Simpsons” co-creator and producer Sam Simon died following a battle with colon cancer, it was announced on Monday. He was 59.

After being given three months to live following his diagnosis in 2012, Simon dedicated his $100 million fortune to charitable causes, chiefly the Sam Simon Foundation, which trains service dogs for the hearing impaired and returning veterans suffering post-traumatic stress disorder.

In August, the reputed animal rights activist teamed with Fusion on a documentary that chronicled Simon’s fight with his terminal disease and his efforts to rescue animals from harmful and abusive conditions.

The Sam Simon Foundation issued the following Facebook post on Monday:

Simon began his career drawing cartoons for two San Francisco newspapers before submitting an unsolicited script for an episode of the ABC series "Taxi." It eventually aired and he was subsequently made a writer on the show after which he made stops on "Barney Miller," long-running NBC sitcom "Cheers" and Fox's "It's Garry Shandling's Show." In 1989 Simon created "The Simpsons" alongside Executive Producer James L. Brooks and cartoonist Matt Groening. During his tenure, "The Simpsons," now in its 26th season, became a cultural phenomenon, spawning a litany of consumer products and catchphrases, and reaching its TV ratings zenith in 1990, with 33.6 million viewers.

Co-creators Brooks and Groening also offered statements on Simon's passing.

"He is gone from our industry too soon."

“He was truly one of the great ones. He found so much outside the work to give him pleasure and left so much behind for others,” Brooks said.

By the time of his passing, Simon's philanthropic efforts had extended to marine-wildlife conservation and whale preservation, as well as free vegan meals for the disadvantaged.

Simon, who was once married to actress Jennifer Tilly, was unmarried and did not have any children.
