Harald Schäfer

Harald Schäfer is a chemistry 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 Harald Schäfer rather than just read about it. In short: Harald Schäfer (10 February 1913, Jena – 21 December 1992, Münster) was a professor of inorganic chemistry at the University of Münster in Germany. He is recognized for popularizing the use of chemical vapor transport and the discovery of many new inorganic compounds.

Key takeaways

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

Reference excerpt

Harald Schäfer (10 February 1913, Jena – 21 December 1992, Münster) was a professor of inorganic chemistry at the University of Münster in Germany. He is recognized for popularizing the use of chemical vapor transport and the discovery of many new inorganic compounds. Schäfer began his studies in 1937 and was awarded a doctorate in 1940. His dissertation was on analytical chemistry of boron. He conducted his habilitation at the Technical University of Stuttgart on iron oxychlorides, during which he discovered the phenomenon of chemical vapor transport (migration in the solid state via the gas phase). In recognition of his research achievements, he was awarded the Alfred Stock Memorial Prize in 1967. He was also elected to the Leopoldina Academy.

Worked examples

Example 1 — a first encounter with Harald Schäfer

Start with the simplest possible case. Write down what Harald Schäfer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Harald Schäfer 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 Harald Schäfer 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 Harald Schäfer

In research
Harald Schäfer appears in chemistry 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 Harald Schäfer 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
Harald Schäfer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1992 deaths, 20th-century German chemists, so understanding it makes those chapters shorter.
In everyday life
Look for Harald Schäfer 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.
