Aristotle was the blind Sesame Street monster created to increase disability inclusion on the show.
Aristotle was designed as a blind Muppet whose presence helped Sesame Street represent disability within its monster community. The character was intended to show that blindness could be part of a person’s identity without defining the person’s entire personality or limiting participation in the Street’s activities.
The character was designed by Michael K. Frith and built by Ed Christie. Richard Hunt performed Aristotle, linking the character to one of Sesame Street’s most important early generations of puppeteers. Aristotle is listed among the show’s Muppet characters rather than among its human cast members.
Sesame Street had already used real people with disabilities in its educational storytelling, including deaf librarian Linda Bove and children and adults with other disabilities. Aristotle belongs to that broader tradition of inclusion, but he should not be confused with Julia, the autistic girl introduced much later, or with Telly Monster and Herry Monster, who are not blind characters. Frazzle is another monster altogether and is not the answer to this clue.
