Norman W. Johnson is a mathematician, previously at Wheaton College, Norton, Massachusetts. He earned his Ph.D. from the University of Toronto in 1966 with a dissertation title of The Theory of Uniform Polytopes and Honeycombs, his thesis advisor being the famous H. S. M. Coxeter.
In his 1966 doctoral thesis Johnson discovered a small regiment of three uniform antiprism-like star-polychora named the Johnson antiprisms.
In 1966 he enumerated 92 convex non-uniform polyhedra with regular faces. Victor Zalgaller later proved (1969) that Johnson's list was complete, and the set is now known as the Johnson solids.
More recently, Johnson has participated in the Uniform Polychora Project, an effort to find and name higher-dimensional polytopes.
