Neal Hooker Williams (1870–1956) was a
physicist notable for the very first
spectroscopic measurements at
microwave frequencies. He carried this out with a
magnetron and investigated the
spectrum of gaseous
ammonia together with his student

. This formed the groundwork for the later inventions of the
radar and the gas
laser.
Education
He completed his PhD in 1912 at the
University of Michigan with a thesis entitled ''The Stability of Residual Magnetism.''
