You may be saying to yourself, "Who was Jerry Nelson?" You may not know the man, but you certainly know the Sesame Street characters he created. There's Count von Count, otherwise known as The Count, Herry Monster, Sherlock Hemlock, and others. Jerry Nelson passed away last week, and human or Muppet, we all mourn his loss.
Nelson was also the creator of Gobo Fraggle. You can view an episode of the series, Fraggle Rock, on The Song of the Cloud Forest and Other Earth Stories [J DVD SON].
