Reference excerpt

Michael Joseph François Scheidweiler (1 August 1799 – 24 September 1861) was a German-born professor of botany and taxonomist, whose main area of interest was the Cactaceae. From a collection by Henri Guillaume Galeotti, he first described Ariocarpus retusus, type species of the genus in 1838 in Brussels.

Life Scheidweiler was born in Cologne on 1 August 1799 and after studying humanities in Siegburg he qualified as a pharmacist in Cologne. He returned to Siegburg for a year before embarking on travels through much of Germany and Switzerland to acquire botanical knowledge, and then worked as a pharmacist and industrial chemist in Cologne and Aachen, where he married. In 1830 he settled in Belgium, first in Liège, later in Brussels, where he lectured on natural history at the Établissement Géographique de Bruxelles that Philippe Vandermaelen had established in 1830 and, from its foundation in 1836, at the State School of Veterinary Medicine and Agriculture (now the Faculty of Veterinary Medicine, University of Liège). In 1850 he launched the short-lived journal L'agriculteur belge et étranger. In 1851 he was appointed instructor at the State School of Horticulture in Gentbrugge that Louis van Houtte had founded in 1849. In 1854, the genus Scheidweileria (family Begoniaceae) was named in his honor by Johann Friedrich Klotzsch. He died in Ghent on 24 September 1861.

Publications Cours raisonné et pratique d'agriculture et de chimie agricole, 2 volumes (1841-1843). Traité théorique et pratique de l'élève et de l'amélioration des bêtes à cornes (1855). Together with Pierre-Victor Royer, Scheidweiler translated Matthias Jakob Schleiden's Die Pflanze und ihr Leben (1848) into French as La plante et sa vie (1859). Scheidweiler was an active contributor to the Journal d'horticulture pratique (of which he served as editor for a short while) and to the Annales de pomologie belge et étrangère

Author abbreviation Scheidweiler is denoted by the author abbreviation Scheidw. when citing a botanical name.

Worked examples

Example 1 — a first encounter with Michael Joseph François Scheidweiler

Start with the simplest possible case. Write down what Michael Joseph François Scheidweiler 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 Michael Joseph François Scheidweiler 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 Michael Joseph François Scheidweiler 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 Michael Joseph François Scheidweiler

In research: Michael Joseph François Scheidweiler 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 Michael Joseph François Scheidweiler 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: Michael Joseph François Scheidweiler is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1799 births, 1861 deaths, 19th-century Belgian botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Michael Joseph François Scheidweiler 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.
