Puppeteer Behind 'Big Bird' Dies at 85 VOA News You didn't know his name, but you certainly knew his voice and alter ego. Caroll Spinney, the puppeteer who played Big Bird and Oscar the Grouch for nearly 50 years on TV's Sesame Street, died Sunday at his home in Connecticut. He was 85. The Sesame Workshop, which produces the show, says Spinney had been suffering from dystonia -- a disease that causes involuntary muscle movements. Spinney introduced Big Bird and Oscar on Sesame Street's first episode in November 1969. The show's young audience immediately embraced both characters. The yellow feathered Big Bird stood two and a half meters tall and had a child's view of the world -- he was filled with curiosity, questions, and innocence. .
