Reference excerpt

Henry Barnard Kümmel (1867 - October 23, 1945) was a State Geologist for the State of New Jersey during the 20th century who worked extensively in the management of the Morris Canal after its acquisition by New Jersey.

Biography Kümmel was born in 1867 in Milwaukee, Wisconsin. His wife was Charlotte C. Kümmel. He studied geology under Rollin D. Salisbury at Beloit College, furthering his studies with graduate work at Harvard and the University of Chicago. Kümmel was an elder at Prospect Street Church and sat on the judicial commission for the trial of Rev. Dr. J. Gresham Machen in 1935, but resigned his post before the conclusion of the trial. Two quit board in Machen trial; Successors chosen after one of those named is said to sympathize with pastor. Kümmel died 23 October 1945 at home in Trenton, New Jersey, following a lengthy illness.

Career On May 12, 1908, Kümmel became the founding chairman of the Association of American State Geologists (AASG) in Washington, D.C. In the 1930s, Kümmel compiled the "Henry B. Kümmel Collection" of photographs maintained by the New Jersey State Archives, including many historically significant images of the Morris Canal. Kümmel's work on the Morris Canal also led the way for the preservation of the Pequannoc Spillway and Pompton Dam in Pequannock, NJ through his proclamation that to remove them would reduce the surrounding area to a series of "ill smelling mud flats," a statement quoted by consulting engineer Cornelius Clarkson Vermeule II upon his decision to preserve the structures. As New Jersey State Geologist, Kümmel contributed to a large number of reports of great historic significance to the State of New Jersey, including the annual report for 1910, reports on the decommissioning of the Morris Canal, and a report describing glacial drift cited extensively by The New York Times. Kümmel also served as director of the Department of Conservation and Development, where on May 19, 1932, he presided over the acceptance of 2,500 plants for the George Washington Memorial Arboretum at Washington Crossing State Park from Charles Lathrop Pack and his son Arthur Newton Pack.

Worked examples

Example 1 — a first encounter with Henry Barnard Kümmel

Start with the simplest possible case. Write down what Henry Barnard Kümmel 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 Henry Barnard Kümmel 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 Henry Barnard Kümmel 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 Henry Barnard Kümmel

In research: Henry Barnard Kümmel 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 Henry Barnard Kümmel 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: Henry Barnard Kümmel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1867 births, 1945 deaths, American geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Henry Barnard Kümmel 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.
