Hans Erlenmeyer

Hans Erlenmeyer 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 Hans Erlenmeyer rather than just read about it. In short: Hans Friedrich Albrecht Erlenmeyer (March 20, 1900, in Strasbourg – May 29, 1967, in Basel) was a German-Swiss chemist and collector of antiquities. He was a professor of inorganic chemistry at the University of Basel.

Key takeaways

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

Reference excerpt

Hans Friedrich Albrecht Erlenmeyer (March 20, 1900, in Strasbourg – May 29, 1967, in Basel) was a German-Swiss chemist and collector of antiquities. He was a professor of inorganic chemistry at the University of Basel.

Life and career Hans Erlenmeyer came from a family of chemists; his grandfather Emil Erlenmeyer and his father Emil Erlenmeyer Jr. were both chemistry professors. Erlenmeyer studied chemistry from 1918 to 1922 at the Friedrich Schiller University of Jena and the Humboldt University of Berlin, where he received his doctorate in 1922 with a thesis entitled "On Asymmetric Synthesis". He worked as an assistant to Bernhard Lepsius. In 1925, he became an assistant to Friedrich Fichter in Basel, and in 1927 he habilitated in inorganic chemistry. He became an associate professor in 1933, and in 1941 he succeeded Fichter as full professor and head of the Institute of Inorganic Chemistry. Erlenmeyer was involved in approximately 500 publications on structural chemistry and immunology, particularly fundamental research for chemotherapy of tuberculosis. He also helped develop the concept of isosteres. He obtained Swiss citizenship in 1934. He helped many victims of Nazism at his institute in Basel. In 1943 he nominated Tadeusz Reichstein, who also lectured in Basel to the Nobel Prize in Chemistry, but at the time Reichstein was not elected. But in 1950, Reichstein then was awarded the Nobel Prize in Physiology or Medicine. Together with his second wife Marie-Louise Erlenmeyer (1912-1997), he collected prehistoric and ancient art from Greece and Mesopotamia. The purchases were made between 1943 and the early 1960s. The Erlenmeyers partially loaned their pieces to the Antikenmuseum Basel and to major international exhibitions and also wrote scientific publications in the field of archaeology. In the late 1950s or early 1960s, they bought large parts of the so-called Keros Hoard from an art dealer of Greek descent. The hoard included both the largest known Cycladic idol and over 150 fragments of other idols as well as ceramics and other objects. Greece later claimed restitution of the largest idol because, like the entire hoard, it was illegally smuggled out of the country from a looted site. Since this happened before the 1970 UNESCO Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property, the collectors' actions were considered in good faith. In 1981, Marie-Louise Erlenmeyer founded the Erlenmeyer Foundation for the benefit of animal and species protection. To support this foundation, the collection was auctioned off in several sales at Christie's and Sotheby's between 1988 and 1998, with the proceeds going towards the foundation. Kurt Aeschbacher is the president of the foundation board as of 2020. Hans Erlenmeyer acquired the Kushim Tablet in the 1950s.

Worked examples

Example 1 — a first encounter with Hans Erlenmeyer

Start with the simplest possible case. Write down what Hans Erlenmeyer 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 Hans Erlenmeyer 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 Erlenmeyer 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 Erlenmeyer

In research
Hans Erlenmeyer 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 Hans Erlenmeyer 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 Erlenmeyer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1967 deaths, 20th-century Swiss chemists, so understanding it makes those chapters shorter.
In everyday life
Look for Hans Erlenmeyer 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.
