Maurice Langeron

Maurice Langeron is a science 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 Maurice Langeron rather than just read about it. In short: Maurice Charles Pierre Langeron (French pronunciation: [mɔʁis ʃaʁl pjɛʁ lɑ̃ʒʁɔ̃]; 3 January 1874, in Dijon – 27 June 1950, in Bourg-la-Reine) was a French mycologist, bryologist and paleobotanist. He studied natural sciences at the Muséum national d'histoire naturelle in Paris.

Key takeaways

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

Reference excerpt

Maurice Charles Pierre Langeron (French pronunciation: [mɔʁis ʃaʁl pjɛʁ lɑ̃ʒʁɔ̃]; 3 January 1874, in Dijon – 27 June 1950, in Bourg-la-Reine) was a French mycologist, bryologist and paleobotanist. He studied natural sciences at the Muséum national d'histoire naturelle in Paris. In 1930 he was named director of the department of mycology in the laboratory of parasitology at the faculty of medicine in Paris. Two years later, he became adjoint-director in the laboratory of parasitology at the École pratique des hautes études. In 1942 he was appointed director of research at the Centre national de la recherche scientifique (CNRS). In 1933 he became a member of the Société de biologie. With Émile Brumpt and Maurice Neveu-Lemaire, he founded the journal Les Annales de Parasitologie humaine et comparée, now continued as Parasite. The dermatophyte:genus Langeronia (Vanbreus., 1950) is named after him.

Written works In 1965 his Précis de mycologie was translated into English and published as "Outline of mycology". Other noted works by Langeron include:

Muscinées de la Côte-d'Or : Études géographiques : Catalogue des muscinées de la Côte d'Or, 1898 – Bryophytes of Côte-d'Or. Contributions a l'étude de la flore fossile de Sézanne, 1899–1902 – Contributions to the study of fossil flora of Sézanne. Le genre Aleurites Forst (Euphorbiacées) systématique, anatomie, pharmacologie, 1902 – The genus Aleurites (Euphorbiaceae); systematics, anatomy and pharmacology. Études sur les végétaux fossiles du Trieu de Leval (Hainaut), 1907 – Studies of fossil flora of Trieu de Leval (Hainaut). Précis de microscopie; technique, expérimentation, diagnostic, 1913 – Outline of microscopy; techniques, experimentation, diagnostics. Coprologie microscopique, 1922 – Microscopy associated with coprology.

Worked examples

Example 1 — a first encounter with Maurice Langeron

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

In research: Maurice Langeron appears in science 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 Maurice Langeron 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: Maurice Langeron is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1874 births, 1950 deaths, French bryologists, so understanding it makes those chapters shorter.
In everyday life: Look for Maurice Langeron 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.
