Why Is John D. Hoffman Influential?
(Suggest an Edit or Addition)According to Wikipedia, John Drake Hoffman was an American chemist and author who was awarded the Soldier's Medal, the United States Army's highest award for an act of valor in a non-combat situation, and the only one awarded to a member of the Manhattan District. After the war he worked for the National Bureau of Standards, becoming the director of its national measurements laboratory. He was a professor and director of the engineering materials program at the University of Maryland from 1982 to 1985, director of the Michigan Molecular Institute, and a professor of materials science and engineering at Johns Hopkins University.
