Reference excerpt

William Ashbrook Kellerman (May 1, 1850 Ashville, Ohio – March 8, 1908) was an American botanist, mycologist and photographer.

Biography Kellerman was born in May 1850 in Ohio, the son of Daniel Kemberling Kellerman and Iva/Ivy Ashbrook Kellerman. His father a merchant and Farmer originally from Pennsylvania did well for himself and put his son in fine schools. He received his Bachelor of Science degree from Cornell University in 1874. After graduation, Kellerman was hired as Professor of Natural Sciences at the Wisconsin State Normal School, a position he held for five years. During this time, in 1876, he married Stella Victoria Dennis, also a botanist. In 1879, the Kellermans moved to Germany, where he attended the Universities of Göttingen and Zurich, where he obtained his Ph.D. in 1881. They returned to the U.S., and he was appointed Professor of Botany and Zoology at the State College (now University) of Kentucky in Lexington. In 1883, he joined the Department of Botany and Zoology at the Kansas State College of Agriculture (now Kansas State University) in Manhattan. He also became state botanist and wrote a pamphlet on the flora of Kansas. In 1891 he became a professor of botany at Ohio State University. One of his students was Lumina Cotton Riddle, the first woman to receive a doctorate in Botany from the university. He studied the smuts (fungal diseases) of wheat and oats, and demonstrated that hot water is an effective fungicide. With Benjamin Matlack Everhart and Job Bicknell Ellis, in 1885 he founded the Journal of Mycology, now Mycologia. In 1904 he began making annual botanical expeditions to Guatemala. It was there in 1908 that he contracted a fever (generally believed to be malaria), died, and was buried in the "cactus fenced cemetery at Zacapa." He edited three exsiccata works. The one with the title Ohio fungi is found in major herbaria. The same is with the series Kansas fungi which he issued with Walter Tennyson Swingle.

Worked examples

Example 1 — a first encounter with William Ashbrook Kellerman

Start with the simplest possible case. Write down what William Ashbrook Kellerman claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 William Ashbrook Kellerman 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 William Ashbrook Kellerman 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 William Ashbrook Kellerman

In research: William Ashbrook Kellerman appears in astronomy 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 William Ashbrook Kellerman 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: William Ashbrook Kellerman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1850 births, 1908 deaths, American botanists, so understanding it makes those chapters shorter.
In everyday life: Look for William Ashbrook Kellerman 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.
