Ultimate crossword clue is revealed – The Yorkshire Post says

The nine-letter answer is, in fact, the invention of one Arthur Wynne, from Liverpool, whose very first crossword was published in 1913 in New York World.

Even though it was another decade before the crossword became a regular platform in newspapers on this side of the Atlantic, including The Yorkshire Post, many readers say that they cannot start their day until they have successfully completed the cryptic puzzle – or quick crossword – published daily.

And the fact that Mr Wynne’s ingenuity – his original crosswords were diamond-shaped – has inspired so many word games and numerical puzzles, like sudoku, is further evidence of how mental stimulus is just as important as physical exercise – even if there is
the very occasional cross word over the correct answer.
