Fraggle Rock (also known as Jim Henson's Fraggle Rock or Fraggle Rock with Jim Henson's Muppets) is a British/American/Canadian children's live action puppet television series about interconnected societies of Muppet creatures, created by Jim Henson.
Heather Beth Henson (born December 19, 1970, in New York City) is a contemporary puppet artist.
 She serves on The Jim Henson Company, The Jim Henson Legacy, and the Jim Henson Foundation Boards of Directors.
 She is also a Trustee of the Eugene O'Neill Theater Center in Connecticut.
Don Sahlin (June 19, 1928 in Stratford, Connecticut – February 19, 1978 in New York City) was a Muppet designer and builder who worked for Jim Henson from 1962 to 1977.
 His first creation for Jim Henson was Rowlf the Dog, which he built in 1962 for a series of Purina Dog Chow commercials.
 Don would go on to design and build most of the Muppet characters, including Bert and Ernie, Grover, and Cookie Monster among others.
 His character designs are often recognizable for their spheroid heads partially bisected to create large mouths.
 Although always based on sketches by Jim Henson, the Muppet founder regularly stated that it was Don who should be credited with creating the actual Muppet "look", and Henson later had a bench in London dedicated to his memory.
 The series finale of "Fraggle Rock" is also dedicated to him.
 After all the regular credits have been shown, a special credit appears which reads "This show is for Don Sahlin".

 He is well known for his analysis of the works of Woody Allen in his books such as "The Films of Woody Allen" (2002) and "A Companion to Woody Allen" (2013) with Peter J. Bailey.
 He believes ultimately that Allen's films undermine the world in which we live.
The Skeksis are a fictional species which act as the main antagonists in the 1982 fantasy film "The Dark Crystal", its companion book "The World of The Dark Crystal" and the Tokyopop prequel "Legends of the Dark Crystal".
 They are also referenced as an alien race in S03E07 of Farscape and are strikingly similar in appearance to the Halosians in S02E09 of the same show, which was produced by Jim Henson Productions.
 The word "Skeksis" serves as both singular and plural form for this species, with the singular being pronounced and the plural .
 They are described by concept artist Brian Froud as, "part reptile, part predatory bird, part dragon."
 In the film, the Skeksis are represented by puppets engineered under the direction of Jim Henson.
 Jim Henson said that in the development of the Skeksis, the creators drew inspiration from the Seven Deadly Sins.
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.

" in 2003.
