Sam Simon, the co-creator of 'The Simpsons' has died at the age of 59 after struggling from colon cancer.

The 'Sam Simon Foundation', which the producer set up in 2002 to rescue dogs from shelters and train them to assist the disabled, announced, the sad demise on their Facebook page, BBC News reported.

Al Jean, a fellow producer, wrote on Twitter that his co-producer was a great man, and he owed him everything.

The Simpson family show first aired in 1989, and its writing department was led by the late American producer for four seasons, and after that he discontinued his services, but continued receiving its earnings as he signed a deal that gave him a part of the show's future earnings.

Simon donated his all money to charity after he was diagnosed with the disease, and even before this he gave much of his money to social causes, especially those working on animal welfare issues.

Simon won many awards for his work as a writer, director and executive producer for the longest-running American television series.
