Co-creator of Sesame Street Lloyd

The co-creator of Sesame Street, the beloved children’s educational TV series, has died aged 93. Lloyd Morrisett’s death was announced by Sesame Workshop, the non-profit he helped establish under the name the Children’s Television Workshop.

Mr Morrisett and Joan Ganz Cooney worked with Harvard University developmental psychologist Gerald Lesser to build the show’s unique approach to teaching that now reaches 120 million children.

Legendary puppeteer Jim Henson supplied the creatures.

The show uses fuzzy monsters such as Elmo and the Cookie Monster to charm and teach generations around the world.

In a statement, Sesame Workshop hailed Mr Morrisett as a “wise, thoughtful, and above all kind leader” who was “constantly thinking about new ways” to educate.

Sesame Street is shown in more than 150 countries, has won 193 Emmys, 10 Grammys and in 2019 received the Kennedy Centre Honour for lifetime artistic achievement, the first time a television programme had been given the award.

Born in 1929 in Oklahoma City, Mr Morrisett initially trained to be a teacher with a background in psychology.

He became an experimental educator, looking for new ways to educate children from less advantaged backgrounds.

Mr Morrisett received his bachelor’s at Oberlin College, did graduate work in psychology at UCLA, and earned his doctorate in experimental psychology at Yale University.

The germ of Sesame Street was sown over a dinner party in 1966, where he met Ms Cooney.

“I said, ‘Joan, do you think television could be used to teach young children?’ Her answer was, ‘I don’t know, but I’d like to talk about it,”’ he recalled to The Guardian in 2004.

The first episode of Sesame Street aired in the autumn of 1969.

It was a turbulent time in America, rocked by the Vietnam War and raw from the assassination of the Rev Martin Luther King Jr the year before.

Sesame Street was designed by education professionals and child psychologists with one goal: to help low-income and minority students aged two to five to overcome some of the deficiencies
