Emmy-winning composer Stephen J. Lawrence, whose work on “Sesame Street” spanned decades, has died at age 82, the nonprofit organization behind the children’s series confirmed.

The musician wrote “more than 300 beloved songs and scores” during his tenure with “Sesame Street,” the Sesame Workshop said Monday.

“Thank you for bringing smiles, laughter, and the gift of music to our neighborhood,” the organization wrote in a Twitter tribute.

A cause of death was not released for Lawrence, who died last Thursday in New Jersey, according to Entertainment Weekly.

Lawrence’s lengthy stint with “Sesame Street” began during the 1980s.

Lawrence also served as the composer on multiple movies, including the 1976 drama “Dragonfly,” the 1976 crime film “Alice Sweet Alice” and the 1978 thriller “Mirrors.”
