Paul Magnus Gross, Sr. (September 15, 1895 – May 4, 1986) was an American chemist and educator at Duke University.
[1][2] Gross' opinions on administrative matters led around 1960 to conflicts with President A. Hollis Edens in what came to be known as the Gross-Edens Affair.
Gross pressed for rapid growth towards national stature as a research university, an outcome that Duke did later achieve.
President Harry S. Truman appointed Gross to the original National Science Foundation board in 1950, a position he held for 12 years.
Gross was awarded the Medal for Merit in 1948 for his invention of a plastic bullet for gunnery training in World War II.
