John M. Samson has edited more than 250 puzzle books for Simon & Schuster's Crossword series and has had several daily and Sunday crosswords published in the New York Times. He recently authored puzzle books for Are You Smarter Than a Fifth Grader? (Harper Collins). John's puzzles have appeared on the back of a Kellogg's cereal box, on the side of a Metro-North Railroad building, in a tree inhabited by Keebler Elves, in a keystone for the H. J. Heinz Company, in a heart for Longevity magazine, and in a three-page centerfold for Golf Digest.
