Kermit the Frog is a Muppet character and Jim Henson's best-known creation. Introduced in 1955, Kermit serves as the straight man protagonist of numerous Muppet productions, most notably Sesame Street and The Muppet Show, as well as in other television series, films, specials, and public service announcements through the years. Henson performed Kermit until his death in 1990; Steve Whitmire performed Kermit from that time until his dismissal in 2016. Kermit is currently performed by Matt Vogel. He was also voiced by Frank Welker in Muppet Babies and occasionally in other animation projects, and is voiced by Matt Danner in the 2018 reboot of Muppet Babies.
