Showing my age here, but I was a huge fan of Will Shortz long before the NYT crossword due his involvement with Games magazine in the 80s. I expect there are other Games fans here. In the age before the internet it was a huge part of my entertainment cycle each month.
Games Magazine was amazing in its early years. Puzzles often were interlinked, and ranged in complexity so that an 8 year old could be completely absorbed and so could a life long puzzle solving grandparent.
While the focus of the article is on crosswords, Will Shortz makes all kinds of puzzles. He has a Sunday Puzzle show he does on NPR which is a word game and he is a prolific author of Sodoku puzzles as well as others. So I'd argue that puzzle master is appropriate.
Love the guy, he's a national treasure.
