Louis Manceaux

Louis Manceaux is a biology 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 Louis Manceaux rather than just read about it. In short: Louis Herbert Manceaux (1865–1934) was a French physician, parasitologist, and co-discover of Toxoplasma gondii with Charles Nicolle in 1908. Biography Manceaux's life is not well known, but he was a physician-scientist recruited by Charles Nicolle to study at the Pasteur Institute of Tunis.

Key takeaways

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

Reference excerpt

Louis Herbert Manceaux (1865–1934) was a French physician, parasitologist, and co-discover of Toxoplasma gondii with Charles Nicolle in 1908.

Biography Manceaux's life is not well known, but he was a physician-scientist recruited by Charles Nicolle to study at the Pasteur Institute of Tunis. He assisted Nicolle with capturing gundi in the Djerid Desert to study a parasite associated with a disease known as oriental sore in North Africa. The parasite observed in the tissue samples rodents was originally named Leishmania gondii in 1908. Upon further analysis, they concluded that the parasite was a newly discovered genus, so it was renamed to Toxoplasma gondii in 1909. After his discovery, Manceaux served as a French military doctor and was on active duty with medical corps during World War I. After retiring from the Army, he went on to work for the Pasteur Intstitute of Paris and practice medicine in Paris.

Worked examples

Example 1 — a first encounter with Louis Manceaux

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

In research: Louis Manceaux appears in biology 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 Louis Manceaux 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: Louis Manceaux is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1865 births, 1934 deaths, French biologist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Louis Manceaux 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.
