Otakar Leminger

Otakar Leminger 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 Otakar Leminger rather than just read about it. In short: Otakar Leminger was a Czech chemist known for work in the area of psychopharmacology. He is more specifically known for the synthesis of the monoamine oxidase inhibitor (MAOI) antidepressant phenelzine (phenethylhydrazine) with Emil Votoček in 1932 and for the synthesis and testing of several scaline psychedelics and related drugs including escaline, proscaline, allylescaline, 3C-P, 3-methoxy-4-ethoxyphenethylamine…

Key takeaways

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

Reference excerpt

Otakar Leminger was a Czech chemist known for work in the area of psychopharmacology. He is more specifically known for the synthesis of the monoamine oxidase inhibitor (MAOI) antidepressant phenelzine (phenethylhydrazine) with Emil Votoček in 1932 and for the synthesis and testing of several scaline psychedelics and related drugs including escaline, proscaline, allylescaline, 3C-P, 3-methoxy-4-ethoxyphenethylamine (MEPEA), and 3-methoxy-4-allyloxyphenethylamine (MAPEA) in 1972. He worked in Prague and lived in Ústí nad Labem in northern Czechoslovakia. Leminger worked in industry for years before publishing on psychedelics in his retirement. Alexander Shulgin reviewed Leminger's work on psychedelics in his 1991 book PiHKAL (Phenethylamines I Have Known and Loved), by which point Leminger had passed away.

Worked examples

Example 1 — a first encounter with Otakar Leminger

Start with the simplest possible case. Write down what Otakar Leminger 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 Otakar Leminger 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 Otakar Leminger 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 Otakar Leminger

In research: Otakar Leminger 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 Otakar Leminger 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: Otakar Leminger is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chemist stubs, Czech chemists, Czech scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Otakar Leminger 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.
