Paul Auguste Hariot

Paul Auguste Hariot 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 Paul Auguste Hariot rather than just read about it. In short: Paul Auguste Hariot (1854 – 5 July 1917), the son of Louis Hariot (also a pharmacist), was a French pharmacist and noted phycologist, best known for his 1900 publication Atlas Colorié des Plantes Médicinales Indigènes. Hariot took up the position of botanical assistant at the École Supérieure de Pharmacie in the late 1870s during his training in pharmacy in Paris.

Key takeaways

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

Reference excerpt

Paul Auguste Hariot (1854 – 5 July 1917), the son of Louis Hariot (also a pharmacist), was a French pharmacist and noted phycologist, best known for his 1900 publication Atlas Colorié des Plantes Médicinales Indigènes.

Hariot took up the position of botanical assistant at the École Supérieure de Pharmacie in the late 1870s during his training in pharmacy in Paris. On qualifying in 1882, his rather quiet and studious life was changed by an invitation to accompany the botanist Émile Bescherelle (1828-1903) on an expedition to Cape Horn aboard the ship La Romanche, a trip during which he amassed a fine collection of algae. On returning to France he studied natural sciences and was awarded a degree in 1888 whereupon he joined the National Museum of Natural History in Paris, working in the cryptogamic herbarium under Professor van Tieghem. Here he worked on classifying specimens that had been gathered by Sébastien Vaillant (1669-1722), and those of the brothers Edmond and Charles Tulasne. He revised when necessary the taxonomy and systematics of the species described, and his name appears frequently as a second author for many species of algae. In 1890 he was awarded the Prix Montagne by the Academy of Sciences for his monograph on terrestrial algae of the genus Trentepohlia. He was awarded the Prix Desmazières for 1913 for his work on marine flora. Besides publishing a guide to phycology in 1892, he contributed to a number of illustrated books on plants, and published the first practical guide to seaweeds from the coast of France. Hariot's main interest was in algae and fungi, and later including the rusts. He was one of the founders of the Plant Pathological Society of France, and at the time of his death, was curator of the Cryptogamic Herbarium at the Jardin des Plantes. He is commemorated by Lagenophora hariotii (Franch.) T.R.Dudley, Chamaeangis hariotiana (Kraenzl.) Schltr., Microterangis hariotiana (Schltr.) Senghas and Saxifraga hariotii Luizet & Soulié.

Worked examples

Example 1 — a first encounter with Paul Auguste Hariot

Start with the simplest possible case. Write down what Paul Auguste Hariot 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 Paul Auguste Hariot 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 Paul Auguste Hariot 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 Paul Auguste Hariot

In research: Paul Auguste Hariot 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 Paul Auguste Hariot 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: Paul Auguste Hariot is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1854 births, 1917 deaths, 19th-century French botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Paul Auguste Hariot 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.
