Question: Who produced the show that gave Nasa Astrounaut Group 14 its name?

Context paragraphs:
Silicon: Silicon is a chemical element with symbol Si and atomic number 14.  A hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor.  It is a member of group 14 in the periodic table, along with carbon above it and germanium, tin, and lead below.  It is rather unreactive, though less so than germanium, and has a very large chemical affinity for oxygen; as such, it was first prepared and characterized in pure form only in 1823 by Jöns Jakob Berzelius.

Carrier Strike Group 14: Carrier Strike Group 14 (CSG-14 or CARSTRKGRU 14, sometimes with the "Fourteen" spelt out) was a U.S. Navy carrier strike group.  The group was for some time the only U.S. carrier strike group that did not have an assigned aircraft carrier or carrier air wing.  As of December 2010, it directed the cruisers  and  .  Carrier Strike Group 14 was seemingly last based at Naval Station Mayport.  Without a carrier flagship, it did not conduct the typical deployments of other carrier strike groups; instead, its two cruisers made independent voyages.

Nowotny phase: In inorganic chemistry, a Nowotny chimney ladder phase (NCL phase) is a particular intermetallic crystal structure found with certain binary compounds. NLC phases are generally tetragonal and are composed of two separate sublattices.  The first is a tetragonal array of transition metal atoms, generally from group 4 through group 9 of the periodic table.  Contained within this array of transition metal atoms is a second network of main group atoms, typically from group 13 (boron group) or group 14 (carbon group).  The transition metal atoms form a chimney with helical zigzag chain.  The main-group elements form a ladder spiraling around the transition metal helix.

Group 14 Rugby League: Group 14 is a rugby league competition in central New South Wales, Australia, run under the auspices of the Country Rugby League.  This Group doesn't officially field a senior competition although the Castlereagh Cup is mostly made up of Group 14 clubs.  The Group 14 name is still applied to the junior competition, which is divided into Eastern and Western divisions.

The Muppet Show: The Muppet Show is a family-oriented comedy-variety television series that was produced by puppeteer Jim Henson and features The Muppets.  After two pilot episodes produced in 1974 and 1975 failed to get the attention of network executives in the United States, Lew Grade approached Henson to produce the programme in the United Kingdom for ATV.  The show lasted for five series consisting of 120 episodes which were first broadcast in Britain between 5 September 1976 and 15 March 1981 on ATV and was shown by the other ITV franchises in the United Kingdom.  The programs were recorded at Elstree Studios, England.

NASA Astronaut Group 14: NASA's Astronaut Group 14 (the Hogs) was announced by NASA on 5 December 1992.  The group's name derived from "The Muppet Show" skit "Pigs in Space" and from the group's sponsorship of a pot-bellied pig at the Houston Zoo.

Rocketdyne E-1: Rocketdyne's E-1 was a liquid propellant rocket engine originally built as a backup design for the Titan I missile.  While it was being developed, Heinz-Hermann Koelle at the Army Ballistic Missile Agency (ABMA) selected it as the primary engine for the rocket that would emerge as the Saturn I.  In the end, the Titan went ahead with its primary engine, and the Saturn decided to use the lower-thrust H-1 in order to speed development.  The E-1 project was cancelled in 1959, but Rocketdyne's success with the design gave NASA confidence in Rocketdyne's ability to deliver the much larger F-1, which powered the first stage of the Saturn V missions to the Moon.

Tin: Tin is a chemical element with symbol Sn (from Latin: "stannum" ) and atomic number 50.  It is a post-transition metal in group 14 of the periodic table.  It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO.  Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4.  Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons.  It has two main allotropes: at room temperature, the stable allotrope is β-tin, a silvery-white, malleable metal, but at low temperatures it transforms into the less dense grey α-tin, which has the diamond cubic structure.  Metallic tin is not easily oxidized in air.

Group 14 hydride: Group 14 hydrides are chemical compounds composed of hydrogen atoms and carbon group atoms (the elements of group 14 are carbon, silicon, germanium, tin, and lead).

Carbene analog: Carbene analogs in chemistry are carbenes with the carbon atom replaced by another chemical element.  Just as regular carbenes they appear in chemical reactions as reactive intermediates and with special precautions they can be stabilized and isolated as chemical compounds.  Carbenes have some practical utility in organic synthesis but carbene analogs are mostly laboratory curiosities only investigated in academia.  Carbene analogs are known for elements of group 13, group 14, group 15 and group 16.
