There he received bachelor's and master's degrees in mathematics from the State College of Washington, now the, and in 1928 received his Ph.D. From for his dissertation On Certain Properties of the Metrical and Generalized Metrical Groups in Linear Spaces of n Dimension. After receiving his degree, Schelkunoff joined 's research wing, which became. In 1933 he and Sally P.

Mead began analysis of propagation discovered analytically by their colleague. Their analysis uncovered the. Schelkunoff appears to have been the first to notice the important practical consequences of the fact that attenuation in the decays inversely with the 3/2 power of the frequency. In 1935 he and his colleagues reported that, then new, could transmit pictures or up to 200 conversations. During his 35-year career at Bell Labs, Schelkunoff's research included, propagation in the atmosphere and in microwave guides,, broad-band, and grounding.

He ultimately served as assistant director of mathematical research and assistant vice president for university relations, taught for five years at, where he retired in 1965, and served as a consultant on for the United States Naval Station at. Schelkunoff received 15 patents, the from the (1942), and the 's (1949).
