Kermit The Frog is puppeteer Jim Henson's most famous Muppet creation, first introduced in 1955. He is the main protagonist of many Muppet projects, most notably as the host of The Muppet Show. Kermit was performed by Henson until his death in 1990. Since then Kermit has been performed by Steve Whitmire. He was voiced by Frank Welker in Muppet Babies and occasionally in animation. The character is known to sing, and also performed a hit single, "The Rainbow Connection" in the 1970s, which was used in the first feature-length Muppet movie, The Muppet Movie.
