Harry Bernard Coonce (born 3/19/1938) is an American mathematician notable for being the originator of the now-popular Mathematics Genealogy Project, launched in 1996, a web-based catalog of mathematics doctoral advisors and students.
The amount of time it took Coonce, without the existence of a central database of such information, to find out that Robertson's advisor was C. Einar Hille, gave him the idea for the project.
Coonce completed his PhD in 1969 at the University of Delaware with a dissertation on A Variational Method for Functions of Bounded Boundary Rotation.
[4] Coonce presently is a retired mathematics professor of Minnesota State University, Mankato.
He married Susan Schilling, a computer scientist who died in 2016.
