Jack Kerouac
Kerouac wrote and reworked new material until the last day of his life. He died in St. Petersburg, Florida during emergency surgery, to try to repair a  caused by cirrhosis, due to his alcohol abuse. He was buried in his hometown, and was hardly remembered there at first. Even though he was world famous, Kerouac earned very little money as a writer. He died with only a few hundred dollars in the bank. It was years before his grave received a headstone.
