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 Claud E. Cleeton. 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. ^[1]
