Neal H. Williams : ウィキペディア英語版 | Neal H. Williams
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.'' 〔http://mirlyn.lib.umich.edu〕
