Ronald M. Foster

Ronald Martin Foster, was an American mathematician at Bell Labs whose work was of significance regarding electronic filters for use on telephone lines. He published an important paper, A Reactance Theorem, which quickly inspired Wilhelm Cauer to begin his program of network synthesis filters which put the design of filters on a firm mathematical footing. He is also known for the Foster census of cubic, symmetric graphs and the 90-vertex cubic symmetric Foster graph.

Education

Foster was a Harvard College graduate S.B., summa cum laude, Class of 1917. He also received two honorary Sc.D.s.
