Simon was diagnosed in late 2012 and was given 3-6 months left to live. However, he defied the odds and continued to fight long after that time frame. As well as working on The Simpsons, which he left after season 4 due to creative difficulties, Simon is well known as a member of PETA and his involvement with The Sam Simon Foundation.
