I've known for a while that there's an anticoagulant named warfarin, but it never occurred to me to look up its etymology; I always just assumed it had something to do with warfare.

But etymology by spelling, as they say, is not spell etymology (or something like that). It turns out that the name derives from the initials of the Wisconsin Alumni Research Foundation (which Wikipedia says funded the key research to develop it), plus the ending of “coumarin” (a related chemical compound).
