Stewart Coffin

Stewart Coffin has been called "the most outstanding designer and maker of interlocking puzzles that the world has ever seen". He is credited with over four hundred designs spanning a huge variety of genres, including striking polyhedral sculptures, ingenious tray-packing challenges, and pioneering examples of interlocking cube puzzles. He has also written extensively on puzzle design and craftsmanship, most notably in his books Geometric Puzzle Design and AP-ART: A Compendium of Geometric Puzzles (see link to the latter below).
