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. He went on to graduate with a BA in Psychology from the University of Georgia.
In 1991, Linz participated in the first O'Neill Puppetry Conference and was hired soon after as a performer for Sesame Street, often assisting and playing various Anything Muppets. Two 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. Linz was later cast as Walter, the newest addition to the Muppet troupe who was introduced in the film The Muppets.
After many years as a Sesame regular, Linz inherited the roles of Herry Monster in 2015, and Ernie in 2017. In the latter year, he also began performing several of the classic Muppet characters, Statler, Robin, Link Hogthrob, and Lips.
Linz has also created and led workshops in television puppetry under the auspices of the Jim Henson Company in Germany, China, Mexico and the United States. Outside of Henson, Linz and fellow Muppet performer Noel MacNeal have taught the "Beyond the Sock" puppetry workshop, held annually at the University of North Texas.
Linz has had great success outside of the Henson universe as well, performing in popular children's series such as Between the Lions (as Theo), The Puzzle Place (Skye), Blue's Room, The Book of Pooh, Cousin Skeeter, It's a Big, Big World (Snook), and Lomax, The Hound of Music (as the title character).
Linz performed on 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.
