Richard H. Wilhelm

Richard Herman Wilhelm (January 10, 1909 – August 6, 1968) was an American chemical engineer notable for developing a new method of fluid separation called chemical parametric pumping. Wilhelm was also notable for pioneering in the development of fluid beds, which according to Princeton University "revolutionized the petroleum-cracking process". Princeton University established Wilhelm Lectures in his honor. Wilhelm was a member of the National Academy of Engineering Fellow of the American Academy of Arts and Sciences, and a chairman of the department of chemical engineering at Princeton University. Princeton University called Wilhelm "an authority on chemical reaction engineering".
