Henno Martin

Henno Martin 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 Henno Martin rather than just read about it. In short: Henno Martin (15 March 1910 – 7 January 1998) was a German professor of geology who, along with Hermann Korn, lived for two and a half years in the Namib Desert to avoid internment during the Second World War. Personal life Martin was born in Freiburg, Germany on 15 March 1910.

Key takeaways

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

Reference excerpt

Henno Martin (15 March 1910 – 7 January 1998) was a German professor of geology who, along with Hermann Korn, lived for two and a half years in the Namib Desert to avoid internment during the Second World War.

Personal life

Martin was born in Freiburg, Germany on 15 March 1910. His studies at the universities of Bonn, Zürich, and Göttingen culminated in a Ph.D on "Post-Archean Tectonics in Southern Central Sweden". In 1935 he emigrated along with Korn to what was then South-West Africa (now Namibia) (a former German colony) and worked as a consulting geologist. Namibia was at that time administered by its neighbor, South Africa and in 1939 South Africa, following the United Kingdom, declared war on Germany. In 1940, fearing internment as enemy aliens by the South African government, Martin and Korn decided to flee into the Namib desert and to wait out the war in the remote and rugged Kuiseb Canyon. They returned to Windhoek in 1942 after Korn developed beri-beri. They were not interned on their return and before the war ended were employed as surveyors by the government. In 1957 Martin wrote The Sheltering Desert, a memoir of his experiences while living in the Namib. The work was first published in German and has been translated into other languages. A 1992 film covers the story.

Career Martin discovered the Messum crater in 1939, the Namibian remainder of a gigantic volcanic eruption that happened before Africa and South America broke apart. This eruption is thought to have been the single largest explosive volcanic eruption in the history of the Earth. After the war he worked as a consulting geologist, specialising in exploration for underground water resources. He selected the locations of boreholes throughout South-West Africa and particularly in the capital Windhoek, where he "provided the city with its first large-scale, reliable source of water". From 1958 to 1960, he taught structural geology at the University of São Paulo. Martin worked for 20 years as Director of the Geological Survey of Namibia. In 1963 he joined the University of Cape Town as director of the Precambrian Research Unit, and in 1964 he became Head of Geology at University of Göttingen. The Geological Society of Namibia, whose honorary patron Martin was, awards the Henno Martin Medal annually for the best scientific publication by a geologist living in Namibia.

Worked examples

Example 1 — a first encounter with Henno Martin

Start with the simplest possible case. Write down what Henno Martin 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 Henno Martin 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 Henno Martin 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 Henno Martin

In research
Henno Martin 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 Henno Martin 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
Henno Martin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1910 births, 1998 deaths, 20th-century German geologists, so understanding it makes those chapters shorter.
In everyday life
Look for Henno Martin 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.

Frequently asked questions

What is Henno Martin in simple terms?

Henno Martin (15 March 1910 – 7 January 1998) was a German professor of geology who, along with Hermann Korn, lived for two and a half years in the Namib Desert to avoid internment during the Second World War. Personal life Martin was born in Freiburg, Germany on 15 March 1910.

Why does Henno Martin matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
