Answer: ARTHUR WYNNE
Explanation: Definition: 9 inventor
R THUR in (NY A NEW)* – "this day" being Thursday makes the cryptic reading work nicely, so perhaps a reason why this puzzle was published today, but surely it isn't right for the surface, as it makes it two days early. (I checked the date in John Halpern's Crossword centenary book, among other sources, so there's no ambiguity about the date of Arthur Wynne's puzzle)
