Background: Kevin Jeffrey Clash (born September 17, 1960) is an American puppeteer, director and producer whose characters include Elmo, Clifford, Benny Rabbit, and Hoots the Owl. Clash developed an interest in puppetry at an early age and began performing for local TV children's shows in his hometown of Baltimore, Maryland, as a teenager. In the early 1980s, he began working in Captain Kangaroo and began performing in Sesame Street in 1984. He was the fifth puppeteer to perform Elmo, the character he became the most famous for and became an executive producer and director for the show.
Context: Kevin Clash was born in Baltimore, Maryland, on September 17, 1960, the third of four children born to George Clash, a flash welder and handyman, and Gladys Clash, who ran a small daycare center in their two-bedroom, one-bath home in the Turner Station of Dundalk, Maryland. Clash developed an interest in puppetry at an early age, inspired by children's shows like Kukla, Fran and Ollie and Sesame Street. He made his first puppet, a version of Mickey Mouse, at the age of 10. When he was twelve, he created a monkey puppet out of the lining of his father's coat. His first performances were for his mother's daycare children.  By the time he was a teenager, he had built almost 90 puppets, which he based upon commercials, popular music, and his friends. While still in high school, Clash performed at venues throughout Baltimore, including schools, churches, fundraisers, and community events. While appearing at a neighborhood festival, Clash was discovered by Baltimore television personality Stu Kerr, who became Clash's first mentor and hired him to perform in the children's show Caboose at Channel 2. Clash also built puppets for the Romper Room franchise. When he was 17, he contacted and met puppeteer Kermit Love, who became Clash's mentor, after seeing Love featured in an episode of the documentary Call It Macaroni. In 1979, on Love's recommendation, Clash appeared as Cookie Monster in the Sesame Street float during the Macy's Thanksgiving Day Parade, and met Jim Henson, who later became his boss, mentor, and good friend.  When he was nineteen, Clash became a puppeteer for Captain Kangaroo, initially as a guest performer, in which he also made occasional on-camera appearances. The producers of Captain Kangaroo used some of Clash's puppet creations for the show. In 1984, Clash had to turn down Henson's offer to work on his film The Dark Crystal because he was working on two TV shows at the same time, Captain Kangaroo and Love's syndicated program The Great Space Coaster, in which he was producer for the first time.
