Background and career
Ernest Gary Gygax ( GHY-gaks; July 27, 1938 – March 4, 2008) was an American game designer and author best known for co-creating the pioneering tabletop role-playing game Dungeons & Dragons (D&D) with Dave Arneson. In the 1960s, Gygax created an organization of wargaming clubs and founded the Gen Con tabletop game convention. In 1971, he co-developed Chainmail, a miniatures wargame based on medieval warfare with Jeff Perren. He co-founded the company TSR (originally Tactical Studies Rules) with childhood friend Don Kaye in 1973. The next year, TSR published D&D, created by Gygax and Arneson the year before. In 1976, he founded The Dragon, a magazine based around the new game. In 1977, he began developing a more comprehensive version of the game called Advanced Dungeons & Dragons. He designed numerous manuals for the game system, as well as several pre-packaged adventures called "modules" that gave a person running a D&D game (the "Dungeon Master") a rough script and ideas. In 1983, he worked to license the D&D product line into the successful D&D cartoon series. Gygax left TSR in 1986 over conflicts with its new majority owner, but he continued to create role-playing game titles independently, beginning with the multi-genre Dangerous Journeys in 1992. He designed the Lejendary Adventure gaming system, released in 1999. In 2005, he was involved in the Castles & Crusades role-playing game, which was conceived as a hybrid between the third edition of D&D and the original version of the game. In 2004, he had two strokes and narrowly avoided a subsequent heart attack. He was diagnosed with an abdominal aortic aneurysm and died in March 2008 at age 69. Following Gygax's funeral, many mourners formed an impromptu game event which became known as Gary Con 0, and gamers celebrate in Lake Geneva each March with a large role-playing game convention in Gygax's honor.
Gygax was born in Chicago, the son of Almina Emelie "Posey" Burdick and Swiss immigrant and former Chicago Symphony Orchestra violinist Ernst Gygax. He was named Ernest after his father, but was commonly known as Gary, the middle name given to him by his mother after the actor Gary Cooper. The family lived on Kenmore Avenue, close enough to Wrigley Field that he could hear the roar of the crowds watching the Chicago Cubs play. At age 7, he became a member of a small group of friends who called themselves the "Kenmore Pirates". In 1946, after the Kenmore Pirates were involved in a fracas with another gang of boys, his father decided to move the family to Posey's family home in Lake Geneva, Wisconsin, where Posey's family had settled in the early 19th century, and where Gary's grandparents still lived. In this new setting, Gygax soon made friends with several of his peers, including Don Kaye and Mary Jo Powell. During his childhood and teen years, he developed a love of games and an appreciation for fantasy and science fiction literature. When he was five, he played card games such as pinochle and then board games such as chess. At age ten, he and his friends played the sort of make-believe games that eventually came to be called "live action role-playing games", with one of them acting as referee. His father introduced him to science fiction and fantasy through pulp novels. His interest in games, combined with an appreciation of history, eventually led Gygax to begin playing miniature war games in 1953 with his best friend, Don Kaye. As teenagers, Gygax and Kaye designed their own miniatures rules for toy soldiers with a large collection of 54 mm and 70 mm figures, where they used "ladyfingers" (small firecrackers) to simulate explosions. By his teens, Gygax had a voracious appetite for pulp fiction authors such as Robert E. Howard, Jack Vance, Fritz Leiber, H. P. Lovecraft, and Edgar Rice Burroughs. He was a mediocre student, and in 1956, a few months after his father died, he dropped out of high school in his junior year. He joined the Marines, but after being diagnosed with walking pneumonia, he received a medical discharge and moved back home with his mother. From there, he commuted to a job as a shipping clerk with Kemper Insurance Co. in Chicago. Shortly after his return, a friend introduced him to Avalon Hill's new wargame Gettysburg. Gygax was soon obsessed with the game, often playing marathon sessions once or more a week. It was also from Avalon Hill that he ordered the first blank hex mapping sheets available, which he then employed to design his own games. About the same time that he discovered Gettysburg, his mother reintroduced him to Mary Jo Powell, who had left Lake Geneva as a child and just returned. Gygax was smitten with her and, after a short courtship, persuaded her to marry him, despite being only 19. This caused some friction with Kaye, who had also been wooing Mary Jo. Kaye refused to attend Gygax's wedding. Kaye and Gygax reconciled after the wedding. The couple moved to Chicago where Gygax continued as a shipping clerk at Kemper Insurance. He found a job for Mary Jo there, but the company laid her off when she became pregnant with their first child. He also took anthropology classes at the University of Chicago. Despite his commitments to his job, raising a family, and attending college, Gygax continued to play wargames. It reached the point that Mary Jo, pregnant with their second child, believed he was having an affair and confronted him in a friend's basement only to discover him and his friends sitting around a map-covered table. In 1962, Gygax got a job as an insurance underwriter at Fireman's Fund Insurance Co. His family continued to grow, and after his third child was born, he decided to move his family back to Lake Geneva. Except for a few months he spent in Clinton, Wisconsin, after his divorce, and his time in Hollywood while he was the head of TSR's entertainment division, Lake Geneva was his home for the rest of his life. By 1966, Gygax was active in the wargame hobby world and was writing many magazine articles on the subject. He learned about H. G. Wells's Little Wars book for play of military miniatures wargames and Fletcher Pratt's Naval Wargame book. Gygax later looked for innovative ways to generate random numbers, and used not only common six-sided dice, but dice of all five Platonic solid shapes, which he discovered in a school supply catalog. Gygax cited as influences the fantasy and science fiction authors Robert E. Howard, L. Sprague de Camp, Jack Vance, Fletcher Pratt, Fritz Leiber, Poul Anderson, A. Merritt, and H. P. Lovecraft.
In 1967, Gygax co-founded the International Federation of Wargamers (IFW) with Bill Speer and Scott Duncan. The IFW grew rapidly, particularly by assimilating several preexisting wargaming clubs, and aimed to promote interest in wargames of all periods. It provided a forum for wargamers via its newsletters and societies, which enabled them to form local groups and share rules. In 1967, Gygax organized a 20-person gaming meet in the basement of his home; this event was later called "Gen Con 0". In 1968, he rented Lake Geneva's vine-covered Horticultural Hall for $50 (equivalent to $460 in 2025) to hold the first Lake Geneva Convention, also known as the Gen Con gaming convention. Gen Con is now one of North America's largest annual hobby-game gatherings. Gygax met Dave Arneson, the future co-creator of D&D, at the second Gen Con in August 1969.
I'm very fond of the Medieval period, the Dark Ages in particular. We started playing in the period because I had found appropriate miniatures. I started devising rules where what the plastic figure was wearing was what he had. If he had a shield and no armor, then he just has a shield. Shields and half-armor = half-armor rules; full-armor figure = full armor rules. I did rules for weapons as well. Together with Don Kaye, Mike Reese, and Leon Tucker, Gygax created a military miniatures society called Lake Geneva Tactical Studies Association (LGTSA) in 1970, with its first headquarters in Gygax's basement. Shortly thereafter in 1970, Gygax and Robert Kuntz founded the Castle & Crusade Society of the IFW. In October 1970, Gygax lost his job at the insurance company after almost nine years. Unemployed and now with five children he tried to use his enthusiasm for games to make a living by designing board games for commercial sale. This proved unsustainable when he grossed only $882 in 1971 (equivalent to $7,012 in 2025). He began cobbling shoes in his basement, which provided him with a steady income and gave him more time for game development. In 1971, he began doing some editing work at Guidon Games, a publisher of wargames, for which he produced the board games Alexander the Great and Dunkirk: The Battle of France. Early that same year, Gygax published Chainmail, a miniatures wargame that simulated medieval-era tactical combat, which he had originally written with hobby-shop owner Jeff Perren. The Chainmail medieval miniatures rules were originally published in the Castle & Crusade Society's fanzine The Domesday Book. Guidon Games hired Gygax to produce a game series called "Wargaming with Miniatures", with the initial release for the series being a new edition of Chainmail (1971). The first edition of Chainmail included a fantasy supplement to the rules. These comprised a system for warriors, wizards, and various monsters of nonhuman races drawn from the works of J. R. R. Tolkien and other sources. For a small publisher like Guidon Games, Chainmail was relatively successful, selling 100 copies per month. Gygax also collaborated on Tractics with Mike Reese and Leon Tucker, his contribution being the change to a 20-sided spinner or a coffee can with 20 numbered poker chips (eventually, 20-sided dice) to decide combat resolutions instead of the standard six-sided dice. He also collaborated with Arneson on the Napoleonic naval wargame Don't Give Up the Ship! Dave Arneson briefly adapted the Chainmail rules for his fantasy Blackmoor campaign. In the winter of 1972–1973, Arneson and friend David Megarry, inventor of the Dungeon! board game, traveled to Lake Geneva to showcase their respective games to Gygax, in his role as a representative of Guidon Games. Gygax saw potential in both games, and was especially excited by Arneson's role-playing game. Gygax and Arneson immediately started to collaborate on creating "The Fantasy Game", the role-playing game that evolved into Dungeons & Dragons. Following Arneson's Blackmoor demonstration, Gygax requested more information from Arneson and began testing ideas for the game on his two oldest children, Ernie and Elise, in a setting he called "Greyhawk". This group rapidly expanded to include Kaye, Kuntz, and eventually a large circle of players. Gygax and Arneson continued to trade notes about their respective campaigns as Gygax began work on a draft. Several aspects of the system governing magic in the game were inspired by fantasy author Jack Vance's The Dying Earth stories (notably that magic-users in the game forget the spells that they have learned immediately upon casting them and must re-study them in order to cast them again), and the system as a whole drew upon the work of authors such as Robert E. Howard, L. Sprague de Camp, Michael Moorcock, Roger Zelazny, Poul Anderson, Tolkien, Bram Stoker, and others. The final draft contained changes not vetted by Arneson, and Gygax's vision differed on some rule details Arneson had preferred. Gygax asked Guidon Games to publish it, but the three-volume rule set in a labeled box was beyond the small publisher's scope. Gygax pitched the game to Avalon Hill, but it did not understand the concept of role-playing and turned down his offer. By 1974, Gygax's Greyhawk group, which had started off with himself, Ernie Gygax, Don Kaye, Rob Kuntz, and Terry Kuntz, had grown to over 20 people, with Rob Kuntz operating as co-dungeon-master so that each of them could referee smaller groups of about a dozen players.
Gygax left Guidon Games in 1973 and in October, with Don Kaye as a partner, founded Tactical Studies Rules. The two men each invested $1,000 in the venture—Kaye borrowed his share on his life insurance policy—to print a thousand copies of the Dungeons & Dragons boxed set. They also tried to raise money by immediately publishing a set of wargame rules called Cavaliers and Roundheads, but sales were poor; when the printing costs for the thousand copies of Dungeons & Dragons rose from $2,000 to $2,500, they still did not have enough capital to publish it. Worried that the other playtesters and wargamers now familiar with Gygax's rules would bring a similar product to the market first, the two accepted an offer in December 1973 from gaming acquaintance Brian Blume to invest $2,000 in TSR to become an equal one-third partner. (Gygax accepted Blume's offer right away. Kaye was less enthusiastic, and after a week to consider the offer, he questioned Blume closely before acquiescing.) Blume's investment finally brought the financing that enabled them to publish D&D. Gygax worked on rules for more miniatures and tabletop battle games including Classic Warfare (Ancient Period: 1500 BC to 500 AD) and Warriors of Mars. TSR released the first commercial version of D&D in January 1974 as a boxed set. The hand-assembled print run of 1,000 copies, put together in Gygax's home, sold out in less than a year. (In 2018, a first printing of the boxed set sold at auction for more than $20,000.) At the end of 1974, with sales of D&D skyrocketing, the future looked bright for Gygax and Kaye, who were only 36. But in January 1975, Kaye unexpectedly died of a heart attack. He had not made any specific provision in his will regarding his share of the company, simply leaving his entire estate to his wife Donna. Although she had worked briefly for TSR as an accountant, she did not share her husband's enthusiasm for gaming, and made clear that she would not have anything to do with managing the company. Gygax called her "less than personable... After Don died she dumped all the Tactical Studies Rules materials off on my front porch. It would have been impossible to manage a business with her involved as a partner." Gygax relocated TSR from the Kaye dining room to the basement at his own house. In July 1975, Gygax and Blume reorganized their company from a partnership to a corporation called TSR Hobbies. Gygax owned 150 shares, Blume the other 100 shares, and both had the option to buy up to 700 shares at any time in the future. But TSR Hobbies had nothing to publish—D&D was still owned by the three-way partnership of TSR, and neither Gygax nor Blume had the money to buy out Donna Kaye's shares. Blume persuaded a reluctant Gygax to allow his father, Melvin Blume, to buy Donna's shares, and those were converted to 200 shares in TSR Hobbies. In addition, Brian bought another 140 shares. These purchases reduced Gygax from majority shareholder in control of the company to minority shareholder; he effectively became the Blumes' employee. Gygax wrote the supplements Greyhawk, Eldritch Wizardry, and Swords & Spells for the original D&D game. With Brian Blume, he also designed the wild west-oriented role-playing game Boot Hill. The same year, Gygax created the magazine The Strategic Review with himself as editor. But wanting a more industry-wide periodical, he hired Tim Kask as TSR's first employee to change this magazine to the fantasy periodical The Dragon, with Gygax as writer, columnist, and publisher (from 1978 to 1981). The Dragon debuted in June 1976, and Gygax said of its success years later: "When I decided that The Strategic Review was not the right vehicle, hired Tim Kask as a magazine editor for Tactical Studies Rules, and named the new publication he was to produce The Dragon, I thought we would eventually have a great periodical to serve gaming enthusiasts worldwide ... At no time did I ever contemplate so great a success or so long a lifespan." TSR moved out from the Gygax house in 1976 into the first professional location it could call home, known as "The Dungeon Hobby Shop". Arneson was hired as part of the creative staff, but was let go after only ten months, another sign that Gygax and Arneson had creative differences over D&D.
The Dungeons & Dragons Basic Set released in 1977 was an introductory version of the original D&D geared toward new players and edited by John Eric Holmes. The same year, TSR Hobbies released Advanced Dungeons & Dragons (AD&D), a completely new and complex version of D&D. The Monster Manual was also released that year and became the first supplemental rule book of the new system, and many more followed. AD&D's rules were not fully compatible with those of the D&D Basic Set, and D&D and AD&D became distinct product lines. Splitting the game lines created a further rift between Gygax and Arneson. Arneson received a ten-percent royalty on sales of all D&D products, but Gygax refused to pay him royalties on AD&D books, claiming that it was a new and different property. In 1979, Arneson sued TSR; they settled in March 1981 with the agreement that Arneson would receive a 2.5-percent royalty on all AD&D products, giving him a six-figure annual income for the next decade. Gygax wrote the AD&D hardcovers Players Handbook, Dungeon Masters Guide, Monster Manual, and Monster Manual II. He also wrote or co-wrote many AD&D and basic D&D adventure modules, including The Keep on the Borderlands, Tomb of Horrors, Expedition to the Barrier Peaks, The Temple of Elemental Evil, The Forgotten Temple of Tharizdun, Mordenkainen's Fantastic Adventure, Isle of the Ape, and all seven of the modules later combined into Queen of the Spiders. In 1980, Gygax's long-time campaign setting Greyhawk was published in the form of the World of Greyhawk Fantasy World Setting folio, which was expanded in 1983 into the World of Greyhawk Fantasy Game Setting boxed set. Sales of the D&D game reached $8.5 million in 1980. Gygax also provided assistance on the Gamma World science fantasy role-playing game in 1981 and co-authored the Gamma World adventure Legion of Gold. In 1979, Michigan State University student James Dallas Egbert III allegedly disappeared into the school's steam tunnels while playing a live-action version of D&D. In fact, Egbert was discovered in Louisiana several weeks later, but negative mainstream media attention focused on D&D as the cause. In 1982, Patricia Pulling's son killed himself. Pulling blamed D&D for her son's suicide and formed the organization B.A.D.D. (Bothered About Dungeons & Dragons) to attack the game and TSR. Gygax defended the game on a segment of 60 Minutes that aired in 1985. Death threats started arriving at the TSR office, so he hired a bodyguard. Nevertheless, TSR's annual D&D sales increased in 1982 to $16 million. In January 1983, The New York Times speculated that D&D might become "the great game of the 1980s" in the same manner that Monopoly was emblematic of the Great Depression. Brian Blume persuaded Gygax to allow Brian's brother Kevin to purchase Melvin Blume's shares. This gave the Blume brothers a controlling interest, and Gygax and the Blumes were increasingly at loggerheads over the company's management by 1981. Gygax's frustrations at work and increased prosperity from his generous royalties brought a number of changes to his personal life. He and Mary Jo had been active members of the local Jehovah's Witnesses, but others in the congregation already felt uneasy about his smoking and drinking; his connection to the "satanic" game D&D caused enough friction that the family finally disassociated themselves from Jehovah's Witnesses. Mary Jo resented the amount of time that her husband spent "playing games"; she had begun to drink excessively, and the couple argued frequently. Gygax had started smoking marijuana when he lost his insurance job in 1970, and he started to use cocaine and had a number of extramarital affairs. In 1983, the two got an acrimonious divorce. At the same time, the Blumes wanted to get Gygax out of Lake Geneva so that they could manage the company without his "interference", so they split TSR Hobbies into TSR, Inc. and TSR Entertainment, Inc. Gygax became president of TSR Entertainment, Inc., and the Blumes sent him to Hollywood to develop TV and film opportunities. He became co-producer of the licensed D&D cartoon series for CBS, which led its time slot for two years. Gygax's life continued to unravel on the West Coast, as he rented an immense mansion, increased his cocaine use, and spent time with several young starlets.
