Gordon Leavitt, a childhood friend of Calhamer's recounted how, when they were boys in La Grange Park, Illinois, he and Calhamer "discovered in the attic a geography book that showed a map of Europe before World War I with the Austro-Hungarian Empire and the old boundaries."  Years later, Calhamer put the memory to good use. He received his bachelor's degree from Harvard University in 1953. In 1954, while enrolled at Harvard Law School, he developed a game of strategy and alliances that put seven players in control of the major powers of the pre-World War I era. Although he did not complete law school, his prototype game, still unpublished, was part of the reason that Sylvania hired him in 1958 to do operations research.
In 1959, Calhamer published his game as Diplomacy and printed 500 copies. After selling all of them in six months, he licensed the game to a publisher. Over the years, Diplomacy has been published in North America by Games Research, Avalon Hill, and Hasbro, and has been published in several different languages in other nations by various publishers. Calhamer's original face-to-face board game has also been played by mail since 1963. More recently, there are internet Diplomacy games, games run through email or in online games with a human game master. Calhamer later invented two other games, but neither achieved anything like the success of Diplomacy.
Calhamer wrote a book, Calhamer on Diplomacy: The Boardgame "Diplomacy" and Diplomatic History, but the game did not provide him with a living. In the 1990s he retired from working as a mail carrier and lived his last years in La Grange Park. 
Calhamer died of natural causes February 25, 2013, at Adventist-La Grange Memorial Hospital in La Grange, Illinois. Mike Webb, vice president of marketing and data services for Alliance Game Distributors, said in a posthumous interview, "In many ways, the hobby-game industry as we know it owes its existence to Allan Calhamer" thanks to Diplomacy's numerous gameplay innovations, specifically the ability to negotiate and deceive other players.
Calhamer met his future wife, Hilda Boling, in New York. The couple were married 45 years and had two daughters together, Tatiana and Selenne.
