American mathematician (1930–2017)
This article is about the pure mathematician Norman Johnson. For the statistician, see
Norman Lloyd Johnson .
Norman Woodason Johnson (November 12, 1930 – July 13, 2017) was a mathematician at Wheaton College , Norton, Massachusetts .[ 1]
Early life and education
Norman Johnson was born on November 12, 1930 in Chicago . His father had a bookstore and published a local newspaper.[ 1]
Johnson earned his undergraduate mathematics degree in 1953 at Carleton College in Northfield, Minnesota [ 2] followed by a master's degree from the University of Pittsburgh .[ 1] After graduating in 1953, Johnson did alternative civilian service as a conscientious objector .[ 1] 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.[ 1]
Career
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 .[ 3] [ 4]
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).[ 5]
Death and final works
He completed final edits for his book Geometries and Transformations just before his death on July 13, 2017, and nearly completed his manuscript on uniform polytopes .[ 1]
