John D. Kraus was born in Ann Arbor, MI in 1910, and earned his B.S., M.S., and Ph.D., the final degree in Physics in 1933, from the University of Michigan. Fascinated with radio as a boy, he became involved with Hertzian waves, first as an amateur and then as a professional.

Before World War II Kraus developed antennas including the corner reflector and W8JK close-spaced array. He also helped construct and operate the University of Michigan 100-ton cyclotron, then the world's most powerful particle accelerator. During World War II, Kraus did degaussing (protecting ships from magnetic mines) at the U.S. Naval Ordnance Laboratory and later developed antennas at the Radio Research Laboratory, Harvard University.
