Louis Henry Mitchell is the Creative Director of Character Design of Sesame Workshop, given that title because he has so many duties. He started working on Sesame Street in 1992. His responsibilities include directing photos of the Sesame Street Muppets, designing DVD covers, designing and co-sculpting the Macy's Sesame Street floats, art directing walk-around versions of the characters, and drawing storyboards. He also co-designed Kami and created and designed Julia, the new Sesame Street Autistic character, both as the illustrated book character as well as designing and art directing the building of the actual Muppet.
