# R. 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.
