LOS ANGELES (AP) — Caroll Spinney, who gave Big Bird his warmth and Oscar the Grouch his growl for nearly 50 years on “Sesame Street,” died Sunday at the age of 85 at his home in Connecticut, according to the Sesame Workshop.

The legendary puppeteer lived for some time with dystonia, which causes involuntary muscle contractions, the Sesame Workshop said in a statement.

Spinney voiced and operated the two major Muppets from their inception in 1969 when he was 36, and performed them almost exclusively into his 80s on the PBS kids’ television show that later moved to HBO. His death comes on the same day that “Sesame Street” is being honored for lifetime achievements in the arts as a Kennedy Center Honors recipient.

“Before I came to ‘Sesame Street,’ I didn’t feel like what I was doing was very important,” Spinney said when he announced his retirement in 2018. “Big Bird helped me find my purpose.”

Through his two characters, Spinney gained huge fame that brought international tours, books, record albums, movie roles, and visits to the White House.
