History & Trivia
The "15 Puzzle" is a sliding square puzzle commonly (but incorrectly) attributed to Sam Loyd. Research by Slocum and Sonneveld (2006) discovered that Sam Loyd did not invent and had nothing to do with promoting or popularizing the 15 Puzzle. The puzzle craze that was created by the 15 Puzzle began in January 1880 in the United States and in April in Europe and ended by July 1880. Loyd first claimed in 1891 that he invented the puzzle, and he continued until his death a 20-year campaign to falsely take credit for the puzzle. Noyes Chapman, the Postmaster of Canastota, New York, was the actual inventor of the puzzle. He had shown a previous version of the puzzle he had designed to his friends, as early as 1874.
