Bob McGrath, one of the founding cast members of Sesame Street, has died at the age of 90.
The actor’s family says he “died peacefully at home”.
McGrath first appeared on Sesame Street in 1969, portraying the friendly music teacher Bob Johnson.
He went on to star on the children’s TV show for nearly 50 years, with his final episode airing in 2017.
He was one of the longest-running human characters on Sesame Street, along with Loretta Long, who played Susan Robinson.
The show’s production company Sesame Workshop said he “embodied the melodies of Sesame Street like no one else”.
“His performances brought joy and wonder to generations of children around the world, whether teaching them the ABCs, the people in their neighbourhood, or the simple joy of feeling music in their hearts.”
