Hans Sennholz

Hans Sennholz is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hans Sennholz rather than just read about it. In short: Hans F. Sennholz (; German: [ˈzɛnhɔlts]; 3 February 1922 – 23 June 2007) was a German-born American Austrian School economist and prolific author who studied under Ludwig von Mises.

Key takeaways

  • Hans Sennholz belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hans Sennholz to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hans Sennholz from memory before moving on to harder problems.

Reference excerpt

Hans F. Sennholz (; German: [ˈzɛnhɔlts]; 3 February 1922 – 23 June 2007) was a German-born American Austrian School economist and prolific author who studied under Ludwig von Mises. A Luftwaffe pilot during World War II, he was shot down over North Africa on 31 August 1942, and spent the remainder of the war in a POW camp in the United States. After returning to Germany, Sennholz took degrees at the universities of Marburg in 1948 and Köln in 1949. He returned to the United States to study for a Ph.D. at New York University where he became Mises' first Ph.D. student in the United States. He taught economics at Grove City College, 1956–1992. After he retired, he became president of the Foundation for Economic Education, 1992–1997.

Early life

World War II He was drafted into the Luftwaffe during World War II and became the pilot of a Messerschmitt Bf 109, earning the Iron Cross for valor from his engagements in Norway, France, and Russia. He was shot down over North Africa on August 31, 1942, at a time when the battle for north Africa was intensifying, and spent the remainder of the war in a POW camp in the United States, ultimately located to a POW camp in Wilson, Arkansas, where he worked from 1945 to 1946 at the Wilson dairy farm "milking 20 cows twice a day".

Wartime diary During his stay in Arkansas, he maintained a journal of his time as a POW. When he was released to Germany in 1946, he gave the journal to a trusted guard. "Please send this to my home when the time comes." But the journal never arrived. In 1964, William Harrison, a factory worker in Jonesboro, Arkansas, found the journal on the bank of Bay Ditch, a drainage artery bordering 'old' Highway 63. In November 1985, Harrison took the journal to Scott Darwin, a professor of German at Arkansas State University. Harrison was told that the obsolete German script could not be translated by anyone on staff. Its translation would come by Erika Cohen, having attended German schools in the 1930s when the style was in use. She was the German-born wife of Robert S. Cohen, M.D.; they married while he was serving in the U.S. Army Medical Corps. The journal told the story of its unidentified author's life as a Luftwaffe pilot, being shot down in north Africa and his subsequent time as a German POW in Arkansas. This, perhaps, was intentional, as POWs were not allowed 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.

Worked examples

Example 1 — a first encounter with Hans Sennholz

Start with the simplest possible case. Write down what Hans Sennholz claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hans Sennholz before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hans Sennholz ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hans Sennholz

In research
Hans Sennholz appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hans Sennholz in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hans Sennholz is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1922 births, 2007 deaths, American libertarians, so understanding it makes those chapters shorter.
In everyday life
Look for Hans Sennholz outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
