I've written here in the past about Jim Thurman, especially about his partnership with a gent named Gene Moss. For several years in the sixties, they were top comedy writers in Hollywood and occasional performers. Most notably, they wrote and did voices for the popular cartoon series, Roger Ramjet, and starred in an extremely hip, adult kids' show called Shrimpenstein that ran on KHJ Channel 9 here in Los Angeles for too short a time. You can read more about them in this piece I posted when Mr. Moss passed away.
Alas, this is the piece about Jim Thurman dying. After he and Moss split up, he went on to become one of the main writers of Sesame Street, for which he won many an Emmy. He had a wonderful and wicked sense of humor and the few times we spoke on the phone, it was in full flower. Sorry to hear about his passing. Here are a few more details, courtesy of Variety.
