Biographer Brian Jay Jones has sold a biography of the late Jim Henson–the genius behind the The Muppet Show and Fraggle Rock. The project is currently untitled.

Jonathan Lyons of Lyons Literary negotiated the deal with senior editor Jill Schwartzman. Jones is the author of Washington Irving: An American Original, and is working and with the blessing of Henson’s family.

Here’s more from the release: “The biography begins with Henson’s days as an early TV pioneer, innovative artist and businessman who created a whole new way to present puppetry in a popular art form for television and motion pictures. It will also cover Henson’s famous creations, such as The Muppet Show, Fraggle Rock and his important contribution to the development and success of Sesame Street, and describe his groundbreaking artistic and technological work that continues to this day.” (Henson is pictured, via)
