Physicists William W. Hansen ad Felix Bloch discuss their discoveries in nuclear magnetic resonance, made at Stanford University around 1936. Both served as consultants for the fledgling Varian Associates Instrument Division, then staffed largely by former Stanford graduate students. (from _The Inventor and the Pilot_ by Dorothy Varian, Pacific Books, Publishers, 1983, pg 254.)
