Sam Simon, 58, is the co-creator (along with Matt Groening) of the Simpsons.  Five months ago, he was diagnosed with terminal colon cancer.  He confirmed back in May that his doctors gave him three to six months to live, and he has vowed to donate nearly all of his sizable Simpsons royalties to charity.  He was married twice before, but has no children, and wants to spread his wealth to two charities he truly loves - helping to feed the hungry, and helping animals.
