	Henry Dudeney - Wikipedia, the free encyclopedia
		Dudeney was born in the town of Mayfield, East Sussex, England.
		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 on article in the English penny weekly Tit-Bits.
		Dudeney continued to exchange puzzles with fellow recreational mathematician Sam Loyd for a while, but broke off the correspondence and accused Loyd of stealing his puzzles and publishing them under his own name.

		Henry the mathematician, of course, has been watching all this, so, later, when he finds that his pipe ashes have set the bed sheet on fire, he is not in the least taken aback.
		Henry the mathematician gazes heavenwards and pulls out an answer from there: "In Britain, there exists at least one field, containing at least one sheep, at least one side of which is fl." Everyone laughs at Henry and the engineer tells everyone Henry's way of putting out a fire.
		Henry: "Mathematicians are better and luckier than all of you because they are judged by their own friends and the standards are exacting.

	Dudeney
		Henry's father was a schoolmaster and his father, Henry's paternal grandfather, although he began life as a shepherd, taught himself mathematics and astronomy and left his life on the hills to become a schoolmaster in Lewes.
		Loyd, Dudeney produced many non-standard chess problems such as one where the White pieces are in their initial position, while Black only has a King which is on its own initial square.
		After Dudeney's death his wife helped edit a collection of his puzzles Puzzles and Curious Problems (1931) and later on she again helped edit a second collection which was entitled A Puzzle Mine.

	Henry Dudeney Biography
		H.E. Dudeney, who was born in 1847 in Mayfleet, Sussex, England was Sam Loyd’s British counterpart.
		Dudeney contributed puzzles to Strand’s Tit-bits column under his pseudonym of Sphinx, and he was soon given his own column, Perplexities.
		Dudeney believed that puzzle-solving was an intellectual process of the highest order and that no-one could be more clear thinking and logical than one who constructed such works.

	Dissection puzzle - Wikipedia, the free encyclopedia
		Puzzle creators Sam Loyd in the United States and Henry Dudeney in the United Kingdom were among the most published.
		Since then, dissection puzzles have been used for entertainment and math education, and creation of complex dissection puzzles is considered an entertaining use of geometric principles by mathmaticians and math students.
		Other dissections are intended to move between a pair of geometric shapes, such as a triangle to a square, or a square to a five-pointed star.

	Haberdasher’s Puzzle
		The Haberdasher's Puzzle, the greatest mathematical discovery of Henry Dudeney, was first published by him in the Weekly Dispatch in 1902 and then as problem no. 26 in The Canterbury Puzzles (1907).
		Two of the hinges bisect sides of the triangle, while the third hinge and the corner of the large piece on the base cut the base in the approximate ratio 0.982: 2: 1.018.
		Dudeney showed just such a model of the solution, made of polished mahogany with brass hinges, at a meeting of the Royal Society on May 17, 1905.

		Today there is scarcely a single puzzle book that does not contain (often without credit) dozens of brilliant mathematical problems that had their origin in Dudeney's fertile imagination.

		Pentomino puzzles have been around since at least the early 1900's, when they were mentioned in The Canterbury Puzzles by Henry Dudeney (Dover Publications, 1986; first published in London, 1907).
		"Henry again stroke Louis with the chessboard, drew blood with the blowe, and had presently slain him upon the place had he not been stayed by his brother Robert.
		According to Dudeney, tradition has it that the chessboard broke into thirteen fragments - twelve unique pentomino shapes and one little piece of four squares only.

	Dudeney - Classic Puzzles
		Henry Ernest Dudeney (1857-1930) was England's greatest composer of puzzles.
		He was a near-contemporary of Sam Loyd, America's greatest puzzle expert, and the two men frequently exchanged puzzles and ideas.
		Many of Loyd's and Dudeney's published puzzles show strong similarities, demonstrating how close their collaboration sometimes was.

	Dudeney number - Wikipedia, the free encyclopedia
		A Dudeney number is an integer that is a Perfect cube such that the sum of its digits forms the cube root of the number.
		The name derives from Henry Dudeney, who noted the existence of these numbers in one of his puzzles, Root Extraction, where a professor in retirement at Colney Hatch postulates this as a general method for root extraction.

	Dudeney, Henry Ernest (1857-1930)
		In 1893 he struck up a correspondence with the American puzzle-maker Sam Loyd, the other leading mathematical recreationist of the day, and the two shared many ideas.
		However, a rift developed after Dudeney accused Loyd of publishing many of Dudeney's puzzles under his own name.
		One of Dudeney's daughters "recalled her father raging and seething with anger to such an extent that she was very frightened and, thereafter, equated Sam Loyd with the devil." Dudeney was a columnist for the Strand Magazine for over 30 years and wrote six books.

		He himself was a mathematician who enjoyed creating logic puzzles, and contributed many of these to magazines under the pseudonym "Sphinx." In addition, he self-published many of his own collections of puzzles.
		Dudeney is also credited with creating "verbal arithmetic," a complex logic puzzle in which words are given number values to add up to other words.

	Mathematical Recreations
		In his 1917 book Amusements in Mathematics, English puzzle maker Henry Ernest Dudeney described a fanciful problem based on the Battle of Hastings, the famous confrontation in 1066 between the Saxons under King Harold and the Normans under William the Conqueror.
		With a bit of effort you should be able to find out what happens for D =60 and D =62, on either side of Dudeney's cunning 61 (the answers are provided at the end of the column).
		Mind you, Dudeney could have made the puzzle a lot harder: with D = 1,597, the smallest solutions for x and y are ap proximately 1.3 x 1046 and 5.2 x ~ And D = 9,781 is even worse.

		But if you imagine the room as a box and then fold out the sides, you will see that the "straight line" from the spider to the fly passes through a point P that is not a corner point.
		The original version of the problem, in which dimensions were given and the spider and fly were not in corner positions, was published in an English newspaper by Henry Ernest Dudeney in 1903.
		Dudeney's original version can be found at the MathWorld site.

		Dudeney presented a solution to a puzzle of fitting the twelve pentomino shapes together with one square tetromino--four squares joined together-- on a 8-by-8 checkerboard.
		This puzzle is considered the oldest of the pentomino puzzles and it comes with a fictional story.
		The son of William the Conqueror retaliated by breaking the chessboard over the dauphin's head, breaking the chessboard into thirteen pieces--12 pentominoes and 1 tetromino--which then had to be put back together.

		Two players alternately turn down a card and add it to the common score, and the player who makes the score of 22, or forces his opponent to go beyond that number, wins.
		Again, supposing the play was 3-1, 1-2, 3-3, 1-2, 1-4, scoring 21, the second player would win again, because there is no 1 left and his opponent must go beyond 22.

		The object was to replace the seven numerals in the verse with seven words, which when listed in their given order form a magic word square, where the seven words read the same both across and down.
