Jeremiah Farrell (December 12, 1937 – July 4, 2022) was an American mathematician and academic who was professor emeritus of mathematics at Butler University in Indiana.
Farrell was best known for constructing many crossword puzzles for The New York Times, starting in the 1970s for editor Margaret Farrar and continuing when Will Shortz took over in 1993.
The puzzle had two correct solutions: "Bob Dole elected" and "Clinton elected", and all the crossing words were designed such that they could be one of two different words, to make either answer work.
With his wife Karen, Farrell helped organize the biannual Gathering for Gardner conferences, which started in 1993 as an invitation-only event for people connected with Martin Gardner.
In 2006 Farrell and his wife took over from A. Ross Eckler Jr. as editors and publishers of the quarterly publication Word Ways: The Journal of Recreational Linguistics, established in 1968.
