TOM: Ethan and I became friends when we were assigned lab partners in high school chemistry class (thank you, late-alphabet names!). Our luck continued as lab partners in physics senior year and when we got into the same college.
ETHAN: After graduation in 2020, I constructed a mini-crossword for Harvard's version of Class Notes ("The Red Book"), where I mentioned that I hoped to have a puzzle in the Times one day.
TOM: I solved Ethan's puzzle and asked him if he wanted to collaborate — very happy he said yes!
ETHAN: As a solver, my favorite themes involve simple words parsed in surprising ways, so after realizing that BOXER could be a command, I was ecstatic. We started brainstorming themers around the holidays when stacks of FERRERO ROCHER chocolates were lying around my house. I noticed that ER appeared three times, and I told Tom we had struck gold.
TOM: ROGER FEDERER is probably our favorite theme entry. Ethan and I are both tennis fans, but when we constructed this puzzle, we had no idea he would be retiring so soon. We hope the puzzle can also be a small tribute to him!
