Reference excerpt

John Rockefeller Prentice (December 17, 1902 – June 13, 1972) was an American attorney and member of the prominent Rockefeller family. He was born to Chicago lawyer Ezra Parmalee Prentice and Alta Rockefeller Prentice in New York. Prentice's maternal grandfather was the Standard Oil tycoon, John D. Rockefeller (1839–1937).

Biography While attending Yale University, Prentice became a member of the Skull and Bones society and was elected to Phi Beta Kappa. He graduated in 1928. During his years at Yale, Prentice had accumulated debts and consequently was cut off from his parents. He worked in Boston for a wholesale hardware firm for four years to make enough money to return to Yale. Upon his return to the Ivy League school, Prentice continued to work to support himself. He graduated from Yale Law School in 1932 and practiced law with a Chicago law firm throughout the 1930s. In March 1941, before the Japanese attack at Pearl Harbor, Prentice volunteered in the U.S. Army as a private. While serving in the Pacific Theatre of World War II, he became a captain in the artillery. Prentice became a cattle breeder and is known as a pioneer of artificial insemination in farm animals as a means of improving their genetic pool.

Personal life On August 11, 1941, Prentice married Abbie Cantrill. The couple had one daughter, Chicago philanthropist, Abra Prentice Wilkin.

Worked examples

Example 1 — a first encounter with John Rockefeller Prentice

Start with the simplest possible case. Write down what John Rockefeller Prentice 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 John Rockefeller Prentice 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 John Rockefeller Prentice 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 John Rockefeller Prentice

In research: John Rockefeller Prentice 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 John Rockefeller Prentice 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: John Rockefeller Prentice is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1902 births, 1972 deaths, Agriculture stubs, so understanding it makes those chapters shorter.
In everyday life: Look for John Rockefeller Prentice 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.
