As far as I know this puzzle first appears as ''A Crease Problem'' in 'Modern Puzzles' by Henry Ernest Dudeney', which was published by C. Arthur Pearson in London in 1926.


The puzzle also appears:


In '536 Puzzles and Curious Problems' by Henry Ernest Dudeney, which was published by Charles Scribner's Sons in New York in 1967. It is a combination of almost all the material previously published in Dudeney's 'Modern Puzzles' and 'Puzzles and Curious Problems', edited into a single volume by Martin Gardner.




In an article titled 'About origami, the Japanese art of folding objects out of paper' by Martin Gardner, which was published in the July 1959 issue of 'Scientific American'.

The solutions were given in the August 1959 'Mathematical Games' column.
