Reference excerpt

Lewis B. Allyn (Louis) (July 3, 1874 – May 7, 1940, in Westfield, Massachusetts) was an American chemistry professor and influential figure in the pure food movement at the time of his murder. He was teaching at Westfield Teachers College and contributing as a pure foods expert for McClure's magazines at the time of his shooting. His is the only unsolved murder in the history of Westfield, Massachusetts.

Murder and investigation According to Thomas F. Moriarty, the District Attorney at the time, a witness reported that she was parked 300 feet away when he was murdered. He said she recalled that "a man, wearing dark glasses with his coat collar pulled up was seated behind the wheel of the car," and that a black sedan was involved. Authorities believed at the time that Professor Allyn was murdered because he refused to hand over a very important secret vitamin formula that was "a vitally important military factor." They added that the nation who was requesting it was "a European nation at war." At the moment of the murder, the only European nations at war with one another were Germany, France and the United Kingdom, though Germany had already occupied several other European nations. It was only three days after Professor Allyn's murder that Hitler began an invasion of the Netherlands, Belgium, and Luxembourg, ending the phoney war. A friend of Professor Allyn's verified that an effort by the unnamed nation was made to convince the professor to take an all-expense paid trip there to discuss obtaining the formula, but the professor steadfastly refused on the very day he was slain. The nation at the time was left unnamed.

Worked examples

Example 1 — a first encounter with Louis B. Allyn

Start with the simplest possible case. Write down what Louis B. Allyn claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Louis B. Allyn 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 Louis B. Allyn 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 Louis B. Allyn

In research: Louis B. Allyn appears in chemistry 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 Louis B. Allyn 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: Louis B. Allyn is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1874 births, 1940 deaths, 20th-century American academics, so understanding it makes those chapters shorter.
In everyday life: Look for Louis B. Allyn 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.
