A native of Georgia, Peter Linz (b. June 28, 1967) began puppeteering at the age of 3. He entertained his first audience (a group of birthday partygoers) at the age of 8 and was bitten by the Muppet bug at age 10. He went on to graduate with a BA in Psychology from the University of Georgia.
Like many successful Muppet performers, Linz served a term of duty on Sesame Street, performing numerous characters over the course of 20 seasons. Some of his best-known characters, however, emerged on the Disney Channel preschool program Bear in the Big Blue House in the form of a nervous mouse named Tutter and a playful otter named Pip. His newest Muppet character Walter stars in the 2011 film The Muppets.
Linz has had great success outside of the Henson universe as well, performing in popular children's series such as Between the Lions, The Puzzle Place, Blue's Room, The Book of Pooh, Cousin Skeeter, It's a Big, Big World, and Lomax, The Hound of Music, in which he performs the title character.
Linz performed on the stage in the Tony award-winning Broadway musical Avenue Q from 2003-2005 as puppet captain, ensemble member and understudy for Princeton, Rod, Brian, Nicky, Trekkie Monster, and Bad Idea Bear #1.
