**536 PUZZLES & CURIOUS PROBLEMS** *by Henry Ernest Dudeney pdf*

**Henry Ernest Dudeney** (the last name is pronounced with a long “u” and a strong accent on the first syllable, as in “scrutiny”) was England’s greatest maker of puzzles. With respect to mathematical puzzles, especially problems of more than trivial mathematical interest, the quantity and quality of his output surpassed that of any other puzzlist before or since, in or out of England.

Dudeney was born at Mayfield, in Sussex, on April 10, 1857, the son of a local schoolmaster. His father’s father, John Dudeney, was well known in Sussex as a shepherd who had taught himself mathematics and astronomy while tending sheep on the downs above Lewes, a town fifty miles south of London. Later he became a schoolmaster in Lewes. Henry Dudeney, himself a self-taught mathematician who never went to college, was understandably proud to be the grandson of this famous shepherd-mathematician.

Dudeney began his puzzle career by contributing short problems to newspapers and magazines. His earliest work, published under the pseudonym of “Sphinx,” seems to have been in cooperation with the American puzzlist, Sam Loyd.

For a year and a half, in the late 1890’s, the two men collaborated on a series of articles in Tit-Bits, an English penny weekly. Later, using his own name, Dudeney contributed to a variety of publications including The Weekly Dispatch, The Queen, Blighty, and CasselTs Magazine. For twenty years his puzzle page, “Perplexities,” which he illustrated, ran in The Strand Magazine. This was a popular monthly founded and edited by George Ncwnes, an enthusiastic chess player who had also started and formerly edited Tit-Bits.

“Amusement is one of the fields of applied mathematics.”
