James Maury "Jim" Henson (September 24, 1936 - May 16, 1990) was an American puppeteer, artist, cartoonist, inventor, screenwriter, and filmmaker who achieved international fame as the creator of the Muppets. He was born in Greenville, Mississippi and raised in Leland, Mississippi and Hyattsville, Maryland. Henson began developing puppets while attending high school. He created Sam and Friends while he was a freshman at the University of Maryland, College Park, a five-minute sketch-comedy puppet show that appeared on television.

In 1969, television producer Joan Ganz Cooney and her staff at the Children's Television Workshop, impressed by the quality and creativity of the Henson-led team, asked Henson and staff to work full-time on Sesame Street, a visionary children's program for public television. This union of talents would become legendary in television entertainment.  Part of the show was set aside for a series of funny, colorful, puppet characters living on the titular street. These included Grover, Bert and Ernie, Cookie Monster, Elmo, Oscar the Grouch, and Big Bird. Henson performed the characters of Ernie, game-show host Guy Smiley, and Kermit, who appeared as a roving television news reporter. It was around this time that a frill was added around Kermit's neck to make him more frog-like. The collar was functional as well: it covered the joint where the Muppet's neck and body met.  At first, Henson's Muppets appeared separately from the realistic segments on the Street, but after a poor test-screening in Philadelphia, the show was revamped to integrate the two, placing much greater emphasis on Henson's work. Though Henson would often downplay his role in Sesame Street's success, Cooney frequently praised Jim's work and, in 1990, the Public Broadcasting Service called him "the spark that ignited our fledgling broadcast service." The success of Sesame Street also allowed Henson to stop producing commercials. He later remembered that "it was a pleasure to get out of that world".  In addition to creating and performing Muppet characters, Henson was involved in producing various shows and animation insets during the first two seasons. During the first, Henson produced a series of counting films for the numbers 1 through 10, which always ended with a baker (voiced by Henson) falling down the stairs while carrying the featured number of desserts. For seasons two to seven, Henson worked on a variety of inserts for the numbers 2 through 12, in a number of different styles, including film ("Dollhouse", "Number Three Ball Film"), stop-motion ("King of Eight", "Queen of Six"), cut-out animation ("Eleven Cheer"), and computer animation ("Nobody Counts To 10"). He also directed the original C Is For Cookie.  Concurrently with the first years of Sesame Street, Henson directed Tales from Muppetland, a short series of TV movie specials: comic retellings of classic fairy tales, aimed at a young audience and hosted by Kermit the Frog. The series included Hey, Cinderella!, The Frog Prince, and The Muppet Musicians of Bremen.
