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.

James Maury Henson was born in Greenville, Mississippi on September 24, 1936, the younger of two children of Paul Ransom Henson (1904-1994), an agronomist for the United States Department of Agriculture, and his wife Betty Marcella (nee Brown, 1904-1992). He was raised as a Christian Scientist and spent his early childhood in Leland, Mississippi, before moving with his family to University Park, Maryland in the late 1940s, near Washington, D.C. He remembered the arrival of the family's first television as "the biggest event of his adolescence," having been heavily influenced by radio ventriloquist Edgar Bergen and the early television puppets of Burr Tillstrom on Kukla, Fran and Ollie and Bil and Cora Baird. He remained a Christian Scientist at least into his twenties when he would teach Sunday School, but he wrote to a Christian Science church in 1975 to inform them that he was no longer a practicing member.  Henson began working for WTOP-TV (now WUSA-TV) in 1954 while attending Northwestern High School, creating puppets for a Saturday morning children's show called The Junior Morning Show. He enrolled at the University of Maryland, College Park as a studio arts major upon graduation, thinking that he might become a commercial artist. A puppetry class offered in the applied arts department introduced him to the craft and textiles courses in the College of Home Economics, and he graduated in 1960 with a BS in home economics. As a freshman, he had been asked to create Sam and Friends, a five-minute puppet show for WRC-TV. The characters on Sam and Friends were forerunners of the Muppets, and the show included a prototype of Henson's most famous character Kermit the Frog. He remained at WRC from 1954 to 1961.  In the show, Henson began experimenting with techniques that changed the way in which puppetry was used on television, including using the frame defined by the camera shot to allow the puppet performer to work from off-camera. He believed that television puppets needed to have "life and sensitivity" and began making characters from flexible, fabric-covered foam rubber, allowing them to express a wider array of emotions at a time when many puppets were made of carved wood. A marionette's arms are manipulated by strings, but Henson used rods to move his Muppets' arms, allowing greater control of expression. Additionally, he wanted the Muppet characters to "speak" more creatively than was possible for previous puppets, which had random mouth movements, so he used precise mouth movements to match the dialogue.  When Henson began work on Sam and Friends, he asked fellow University of Maryland sophomore Jane Nebel to assist him. The show was a financial success but, after graduating from college, he began to have doubts about going into a career performing with puppets. He spent several months in Europe, where he was inspired by European puppet performers who looked on their work as an art form. He and Jane began dating after his return to the United States. They were married in 1959 and had five children: Lisa (b. 1960), Cheryl (b. 1961), Brian (b. 1963), John (b. 1965, d. 2014), and Heather (b. 1970).
