of its author's life as a Luftwaffe pilot, being shot down in north Africa and his subsequent time as a German POW in Arkansas. There was no indication as to the identity of the author. This, perhaps, was intentional, as POWs were not supposed to have personal possessions. In 1988, Harrison published the story, "Who Wrote the Diary", in Die Welt, a large-circulation German newspaper. Willie Weischhoff read the story, which mentioned him by name, and wrote to his friend and fellow German POW, Hans Sennholz, a professor of economics at Grove City College. On October 20, 1988, Harrison received a letter from Sennholz stating: "I am the POW author you have been looking for." Post-war education and career After returning to Germany, Sennholz took degrees at the universities of Marburg in 1948 and Köln in 1949. He then moved to the United States to study for a Ph.D. at New York University. He was Ludwig von Mises' first PhD student in the United States. He taught economics at Grove City College, 1956–1992, having been hired as department chair upon arrival. After he retired, he became president of the Foundation for Economic Education, 1992–1997. Calvinist Political Philosopher, John W. Robbins, pointed out in a book printed in honor of Sennholz shortly after his death that "Sennholz, ... rests his defense of a free society on revelation." Fellow Austrian School economist, Joseph Salerno, praised Sennholz as an under-appreciated member of the Austrian School who "writes so clearly on such a broad range of topics that he is in danger of suffering the same fate as Say and Bastiat. As Joseph Schumpeter pointed out, these two brilliant nineteenth-century French economists, who were also masters of economic rhetoric, wrote with such clarity and style that their work was misjudged by their British inferiors as 'shallow' and 'superficial'." Sennholz's influence 2008 U.S. presidential candidate, Ron Paul, credits his interest in economics to meeting Sennholz and getting to know him well. Peter Boettke, Director of the F. A. Hayek Program for Advanced Study in Philosophy, Politics, and Economics at the Mercatus Center at George Mason University, first learned economics from Sennholz as a student at Grove City College.
