** It’s the Radiotopia fundraiser! Support the show using this link and you’ll get a 20% discount to our new merch store! https://on.prx.org/46XCf1R ** It’s December 24th. Today, we look at a number of puzzle-related stories from the WWII era. This is when the New York Times finally got in the crossword game, codebreakers used puzzles to recruit great minds, and more. Jody, NIki, and Kellie are joined by author and podcast host A.J. Jacobs to discuss what that first crossword looked like, why it was such a hit, and how puzzling can help explain the world. A.J. is the author of “The Puzzler” and also host of the new daily puzzle podcast of the same name — which is produced by our own Jody Avirgan and Brittani Brown!
