Everybody knows Elmo - the fire engine red dynamo with the positive attitude and infectious giggle. He's outgoing and curious - a perennial optimist who's full of wonder as he discovers the world.
Elmo first appeared on Sesame Street in 1979 and was simply known as Little Monster until 1980-81. His personality wasn't fully formed until Kevin Clash began performing the character in 1985. Clash developed the monster's trademark giggle and positive outlook on life and Elmo became a superstar!
