Schelkunoff was born in Samara, Russia in 1897, attended the University of Moscow before being drafted in 1917.
There he received bachelor"s and master"s degrees in mathematics from the State College of Washington, now the University of Washington, and in 1928 received his Doctor of Philosophy from Columbia University for his dissertation On Certain Properties of the Metrical and Generalized Metrical Groups in Linear Spaces of n Dimension.
He crossed Siberia into Manchuria and then Japan before settling into Seattle in 1921. After receiving his degree, Schelkunoff joined Western Electric"s research wing, which became Bell Laboratories. Their analysis uncovered the transverse modes.
Schelkunoff appears to have been the first to notice the important practical consequences of the fact that attenuation in the TE01 mode decays inversely with the 3/2 power of the frequency.
In 1935 he and his colleagues reported that coaxial cable, then new, could transmit television pictures or up to 200 telephone conversations. During his 35-year career at Bell Labs, Schelkunoff"s research included radar, electromagnetic wave propagation in the atmosphere and in microwave guides, short-wave radio, broad-band antennas, and grounding.
He ultimately served as assistant director of mathematical research and assistant vice president for university relations, taught for five years at Columbia University, where he retired in 1965, and served as a consultant on magnetrons for the United States Naval Station at San Diego. He died on May 2, 1992, in Hightstown, New Jersey.
