Under the name Ed Spinney, Caroll Spinney animated a series of black and white cartoons called "Crazy Crayon".
He made an appearance as Big Bird on an episode of Mister Rogers' Neighborhood (1968). Before the show was taped, Fred Rogers wanted to have him remove the Big Bird outfit on the show and discuss the inner workings of it. Spinney objected to this idea, saying that it was important to preserve the sense of wonder and magic that children have about Big Bird. Rogers agreed that Spinney was right, and, instead, Big Bird appeared on the show in a Neighborhood of Make-Believe segment.
Was the commencement speaker at Villanova University, in 2004.
He is retiring from Sesame Street on 18 October 2018.
Met his 2nd wife Debra Spinney on the set of Sesame Street.
