Shares the same birthday (September 24) as original Kermit the Frog Jim Henson.
Performed beloved Muppets Kermit the Frog from 1990, following Jim Henson's passing, through October 2016, when Whitmire was let go from his role with the Muppets, as confirmed by Disney.
Was nicknamed Kermit in his youth because he aspired to become a
puppeteer and even performed with a Kermit which he made. His high
school yearbook even has the name "Kermit" on the front cover.
Once received a plaque from Brian Henson in recognition of Steve performing Kermit for three and a half hours non-stop, during a public appearance.
Had a dream about meeting Jim Henson in a hotel lobby, assuring him that Steve's nervousness about performing Kermit the Frog would pass. The next morning, Steve was confident and able to record the
Kermit voiceovers for The Muppet Christmas Carol.
