Norman Woodason Johnson (November 12, 1930 – July 13, 2017) was an American mathematician at Wheaton College, Norton, Massachusetts.Template:Refn
Early life and educationEdit
Norman Johnson was born on Template:Date2 in Chicago. His father had a bookstore and published a local newspaper.Template:R
Johnson earned his undergraduate mathematics degree in 1953 at Carleton College in Northfield, MinnesotaTemplate:Refn followed by a master's degree from the University of Pittsburgh.Template:R After graduating in 1953, Johnson did alternative civilian service as a conscientious objector.Template:R He earned his PhD from the University of Toronto in 1966 with a dissertation title of The Theory of Uniform Polytopes and Honeycombs under the supervision of H. S. M. Coxeter. From there, he accepted a position in the Mathematics Department of Wheaton College in Massachusetts and taught until his retirement in 1998.Template:R
CareerEdit
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.Template:RefnTemplate:Refn
Johnson is also credited with naming all the uniform star polyhedra and their duals, as published in Magnus Wenninger's model building books: Polyhedron models (1971) and Dual models (1983).Template:Refn
Death and final worksEdit
He completed final edits for his book Geometries and Transformations just before his death on Template:Date2, and nearly completed his manuscript on uniform polytopes.Template:R
