Kermit the Frog: Kermit the Frog is a Muppet character and Jim Henson's most well-known creation.

His first creation for Jim Henson was Rowlf the Dog, which he built in 1962 for a series of Purina Dog Chow commercials.  Don would go on to design and build most of the Muppet characters, including Bert and Ernie, Grover, and Cookie Monster among others.  His character designs are often recognizable for their spheroid heads partially bisected to create large mouths.  Although always based on sketches by Jim Henson, the Muppet founder regularly stated that it was Don who should be credited with creating the actual Muppet "look", and Henson later had a bench in London dedicated to his memory.  The series finale of "Fraggle Rock" is also dedicated to him.  After all the regular credits have been shown, a special credit appears which reads "This show is for Don Sahlin".
