Henry Ernest Dudeney (10 April 1857 - 23 April 1930) was an English author and mathematician who specialised in logic puzzles and mathematical games. He is known as one of the country's foremost creators of mathematical puzzles. Although Dudeney spent his career in the Civil Service, he continued to devise various problems and puzzles. Dudeney's first puzzle contributions were submissions to newspapers and magazines, often under the pseudonym of "Sphinx." Much of this earlier work was a collaboration with American puzzlist Sam Loyd; in 1890, they published a series of articles in the English penny weekly Tit-Bits. Dudeney later contributed puzzles under his real name to publications such as The Weekly Dispatch, The Queen, Blighty, and Cassell's Magazine.

亨利-欧内斯特-杜德尼（1857年4月10日-1930年4月23日）是一位英国作家和数学家，专门研究逻辑谜题和数学游戏。他被誉为英国最重要的数学谜题创造者之一。尽管杜德尼的职业生涯是在公务员系统中度过的，但他仍然继续设计各种问题和谜题。杜德尼的第一批谜题作品是提交给报纸和杂志的，经常以 "斯芬克斯 "的笔名发表。这些早期的作品大多是与美国谜题专家萨姆-罗伊德合作完成的；1890年，他们在英国便士周刊《Tit-Bits》上发表了一系列文章。杜德尼后来用他的真名为《每周快讯》、《女王》、《布莱特》和《卡塞尔杂志》等出版物提供谜题。
