Who was Jim Henson first Muppet?

Jim Henson's first Muppet was a character named Kermit the Frog. Kermit was initially created in 1955 for a television show called "Sam and Friends." This early version of Kermit was made from a green coat and had a more simplistic design compared to the beloved character that would later become a cultural icon. Kermit eventually evolved into Henson's most famous creation and a central figure in the Muppet franchise.
