R. M. Foster
Ronald Martin Foster (3 October 1896 – 2 February 1998), was a Bell Labs mathematician whose work was of significance regarding electronic filters for use on telephone lines. He published an important paper, A Reactance Theorem, (see Foster's 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.
He married Annabel Conover,12 April 1924 and had four children: Ronald Martin Foster, Jr.(1926 - 2006), Hubert Conover Foster (1928 - 2011 ), Theodore Dean Foster (1929 - ), Alan Stuart Foster (1933 - ).
