Derrick Somerset Macnutt (1902–1971) was a British crossword compiler who provided crosswords for The Observer newspaper under the pseudonym Ximenes. His main oeuvre was blocked-grid and "specialty" puzzles. Even though he only provided conventional blocked puzzles once a week for the Observer Everyman series for about two years his strong views on clueing, expressed in his 1966 book, have been a source of debate in the cryptic crossword world ever since.
