Reference excerpt

Hermann Theodor Geyler (15 January 1835 at Schwarzbach – 22 March 1889 at Frankfurt-am-Main) was a German botanist, specializing in paleobotany.

Life Geyler was the son of Hermann Gustav and d’Adelgunde Schiller (née von Schillershausen). He studied botany at Leipzig and Jena and was awarded his doctorate in 1860. From 1864 to 1867, he worked in Basel, Switzerland with Swiss botanist Carl Eduard Cramer, a specialist of fossil woods. He was later named a professor at the Institute of Medicine Senckenberg in Frankfurt, a position he held until 1889. In 1871, he married Anna Thezresia Krahmer and they had one son. He was the second director of the Senckenbergische Naturforschende Gesellschaft (Senckenberg Society of Natural History) from 1873 to 1875 and again from 1877 to 1879. During this period, Geyler greatly expanded their collection of plants to include more than 4,000 varieties.

Works Geyler is notably the author of Über fossile Pflanzen aus Borneo (1875), one of the first works of scholarship on plant fossils of the tropics. Among the species he described is Onychiopsis elongata, a fossil fern of the family Dicksoniaceae, from the Jurassic period.

Worked examples

Example 1 — a first encounter with Hermann Theodor Geyler

Start with the simplest possible case. Write down what Hermann Theodor Geyler 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 Hermann Theodor Geyler 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 Hermann Theodor Geyler 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 Hermann Theodor Geyler

In research: Hermann Theodor Geyler 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 Hermann Theodor Geyler 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: Hermann Theodor Geyler is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1835 births, 1889 deaths, 19th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Hermann Theodor Geyler 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.
