Hans Sennholz (February 3, 1922 - 23 June 2007), professor at Grove City College, was one of a handful of men in intellectual history who were able to perform both of these functions with notable distinction. J. B. Say, Frederic Bastiat, Carl Menger, Eugen von Böhm-Bawerk, Edwin Cannan, the early Lionel Robbins, Henry Hazlitt, William Hutt, Murray Rothbard and Mises himself—these were all men who were blessed with that exceedingly rare combination of abilities needed to conceive new economic truth and to effectively propagate it among the general public.
