Matt James (born 1981) is an American game designer and a decorated veteran of the United States Army.
 As a game designer, James is best known for his online and print works for the "Dungeons & Dragons" fantasy role-playing game published by Wizards of the Coast, "Pathfinder" role-playing game by Paizo, and Privateer Press.
 He has also designed game content for Wolfgang Baur's Kobold Press (formerly Open Design LLC).
 In 2012 James won an ENnie Award for "" and has been nominated for several Origins Awards.
 In 2014, James won an ENnie Award for "".
John Wick is an American role-playing game designer best known for his creative contributions to the Alderac Entertainment Group (AEG) properties "Legend of the Five Rings" and "7th Sea".
 He self-published Orkworld under the Wicked Press banner, and later co-founded the Wicked Dead Brewing Company with Jared Sorensen.
 His games under that company include Cat, Schauermärchen, Enemy Gods, and Thirty.
 He has won the Origins Award for Best Role-Playing Game and Best Collectible Card Game twice (for both the "Legend of the Five Rings" and "7th Sea" role-playing games and collectible card games).
Forgotten Realms is a campaign setting for the "Dungeons & Dragons" ("D&D") fantasy role-playing game.
 Commonly referred to by players and game designers alike as "The Realms", it was created by game designer Ed Greenwood around 1967 as a setting for his childhood stories.
 Several years later, Greenwood brought the setting to the "D&D" game as a series of magazine articles, and the first Realms game products were released in 1987.
 Role-playing game products have been produced for the setting ever since, as have various licensed products including sword and sorcery novels, role-playing video game adaptations (including the first massively multiplayer online role-playing game to use graphics), and comic books.
 The Forgotten Realms is one of the most popular "D&D" settings, largely due to the success of novels by authors such as R. A. Salvatore and numerous role-playing video games, including "Pool of Radiance" (1988), "Eye of the Beholder" (1991), "Baldur's Gate" (1998), "Icewind Dale" (2000) and "Neverwinter Nights" (2002).
Meech Wells (born Cecil D. Womack, Jr.) is a music producer from the United States.
 He works primarily on hip hop music, and has produced or co-produced for artists Snoop Dogg and Shaquille O'Neal.
 Wells is also the son of Motown singer Mary Wells and musician/songwriter, Cecil Womack.
 Being the son of Motown legend Mary Wells may have helped jumpstart Meech Wells' career, but the West Coast rap producer quickly proved his talent and eventually aligned himself with Snoop Dogg, another relationship that definitely didn't hurt his career.
 Before being Snoop's producer of choice during the late 1990s and early 2000s, Wells began his career as part of a funk band called Trey Lewd that also featured Tracey Lewis, George Clinton's son; this provided him with the opportunity to work with Clinton himself.
 By 1993, Wells found himself working alongside producer/rapper Def Jef; the two's production on Shaquille O'Neil's "I Got Skillz" (a surprise hit single) won them instant credentials.
 Throughout the mid-'90s, he continued to hone his craft, working on a number of remix projects before eventually being introduced to Snoop through a friend.
 Before long, the two were working together as a potent duo, beginning with "Still a G Thang," one of the better songs on Snoop's Da Game Is to Be Sold, Not to Be Told.
 Wells produced a few No Limit songs featuring Snoop—Tru's "It's a Beautiful Thang," Silkk the Shocker's "Get It Up"—before playing a major role in bringing a West Coast sound to Snoop's Top Dogg album in 1999: "In Love With a Thug," "Better Days," "Gangsta Ride," among others.
 In 2000 he reprised his role as one of Snoop's producers of choice, producing tracks for Tha Eastsidaz' self-titled debut and Doggy's Angels' Pleezbalevit, as well as Snoop's own Tha Last Meal ("Go Away," "Issues").
Gilbert Rohde (1894–1944), whose career as a furniture and industrial designer helped to define American modernism during its first phase from the late 1920s to World War II, is best known today for inaugurating modern design at Herman Miller Inc.
Ken Rolston is an American computer game and role-playing game designer best known for his work with West End Games and on the hit computer game series "The Elder Scrolls".
 In February 2007, he elected to join the staff of computer games company Big Huge Games to create a new role-playing game.
The Plastic Age is a 1925 black-and-white silent film, starring Clara Bow, Donald Keith, and Gilbert Roland in his film debut.
 The film survives today not only on 16 mm film, but also on video and DVD.
 The film was based on a best-selling novel from 1924 of the same name, written by Percy Marks, a Brown University English instructor who chronicled the life of the fast-set of that university and used the fictitious Sanford College as a backdrop.
 "The Plastic Age" is known to most silent film fans as the very first hit of Clara Bow's career, and helped jumpstart her fast rise to stardom.
 Frederica Sagor Maas and Eve Unsell adapted the book for the screen.
Jacob Franklin "Frank" Mentzer III (born in 1950), is an American fantasy author and game designer best known for his work on early materials for the "Dungeons & Dragons" (D&D) fantasy role-playing game.
 He was a performing folk musician from 1968 to 1975, and played one concert at the White House during the administration of Richard Nixon.
 He was an employee of TSR, Inc. from 1980–1986, spending part of that time as Creative Advisor to the Chairman of the Board, Gary Gygax.
 He also founded the Role-Playing Games Association (RPGA) during his time with TSR.
 He has been closely involved with the world's largest game auction at the Gen Con game convention since 1983, and is an expert on, and a major collector of, family boardgames and role-playing games.
 After Gygax was ousted from TSR at the end of 1985, Mentzer left TSR as well and helped him to start New Infinities Productions Inc. (NIPI).
 When this venture failed, Mentzer left the gaming industry, eventually becoming the manager of a bakery.
 In 2008, he closed down this business and, two years later, announced he was returning to the gaming industry as a founding partner of a new publishing company, Eldritch Enterprises.
Loren Wiseman (March 7, 1951 – February 14, 2017) was an American wargame and role-playing game designer, game developer and editor.
William H. Keith's career started in 1978, when he and his brother J. Andrew Keith had seen ads in "Journal of the Travellers Aid Society" that stated that Game Designers' Workshop (GDW) was seeking authors; Loren Wiseman brought them on to begin freelancing for GDW in 1978 or 1979, and together the three of them set up a lot of the early tone for the "Traveller" universe.
 He has been prolific science fiction author ever since.
 He has been writing under pseudonyms most notably as Ian Douglas: his military science fiction sagas "The Galactic Marines" saga, that's split in three trilogy-arks: Heritage Trilogy, Legacy Trilogy and Inheritance Trilogy as well as the "Star Carrier" saga and his cyber punk series "Cybernarc", written under the pen-name Robert Cain.
