He concluded: “Joan Ganz Cooney, its co-founder and close friend, said it best. “Without Lloyd Morrisett, there would be no Sesame Street.

He was a trusted partner and loyal friend to me for over fifty years, and he will be greatly missed.
Sesame Workshop – then called Children’s Television Workshop (CTW) – created the legendary Sesame Street television show which began airing in November 1969.
The idea for the series began in December 1965 when Morrisett noticed how attached his three-year-old daughter was to the family television, which led him to consider whether it could be used to educate children.
