Joan Ganz Cooney, Co-Founder Of Sesame Workshop

Since the 1970s, The Children's Television Workshop—now called the Sesame Workshop— intended to help low-income children become better prepared for school by using television as a tool. The Sesame Workshop has been much more far reaching, teaching and entertaining millions of kids around the globe. Shows like Sesame Street have become so culturally ubiquitous that it's hard to imagine life before Big Bird.
