“While Rothbard was still busy writing and polishing the manuscript of his magnum opus, Hans Sennholz was already a quality product of Mises’s NYU seminar....And in distinct contrast to Rothbard, who spent nights working or discussing with friends, slept through much of the day, missed deadline after deadline, and tended to be messy and disorderly, Sennholz featured the Teutonic personal virtues of punctuality, orderliness, and reliability.”
—Jörg Guido Hülsmann, Mises: The Last Knight of Liberalism
