Jim Henson: The Guy Who Played with Puppets by Kathleen Krull, illustrated by Steve Johnson and Lou Fancher

From chapters.ca:
Sesame Street and The Muppet Show introduced Jim Henson's Muppets to the world, making Kermit the Frog, Oscar the Grouch, and Big Bird household names. But even as a child in rural Mississippi, listening to the radio and putting on comedy shows for his family, Jim recognized the power of laughter to bring people together. On Sesame Street, Jim's Muppets transformed children's television by making learning fun for kids everywhere. A visionary, Jim always believed that puppets could reach a wider audience. In 1976, he proved it, drawing millions of family viewers to The Muppet Show. With his feature film The Dark Crystal and his Star Wars characters - including Yoda - Jim continued to push the boundaries of what was possible in puppetry until his death in 1990 at the age of 53.
