"Caroll was an artistic genius whose kind and loving view of the world helped shape and define Sesame Street from its earliest days in 1969 through five decades, and his legacy here at Sesame Workshop and in the cultural firmament will be unending," the Sesame Workshop said.
But he never became a household name. "I may be the most unknown famous person in America," Spinney said in his 2003 memoir.
"It's the bird that's famous."
Spinney gave the series its emotional yin and yang, infusing the 2.49m Big Bird with a childlike sweetness often used to handle sad subjects, and giving the rubbish bin-dwelling Oscar, whose voice Spinney based on a New York cabbie, a street-wise cynicism that masked a tender core.
"I like being miserable. That makes me happy," Oscar often said. "But I don't like being happy, so that makes me miserable."
