Harry L. Fisher

Harry L. Fisher is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Harry L. Fisher rather than just read about it. In short: Harry Linn Fisher (19 January 1885 – 19 March 1961) was the 69th national president of the American Chemical Society, and an authority on the chemistry of vulcanization. Fisher was the author of four popular books on the chemistry and technology of rubber, and the holder of 50 patents.

Key takeaways

Harry L. Fisher belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Harry L. Fisher to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Harry L. Fisher from memory before moving on to harder problems.

Reference excerpt

Harry Linn Fisher (19 January 1885 – 19 March 1961) was the 69th national president of the American Chemical Society, and an authority on the chemistry of vulcanization. Fisher was the author of four popular books on the chemistry and technology of rubber, and the holder of 50 patents.

Personal Fisher was born on Jan. 19, 1885, in Kingston, New York. His father was the engineer, who in 1883, took the first locomotive from Kingston, N. Y., to Weehawken, New Jersey, along the tracks of the old New York, West Shore and Buffalo Railroad. In 1910, he married Nellie Edna Andrews. They had a son and two daughters. Fisher was said to enjoy "color photography, singing and mountain climbing". Fisher died on 19 March 1961.

Education After finishing High School, Fisher worked for three years before taking a year of refresher coursework at Dwight School in New York City. He went on to study at Williams College in Williamstown, Mass. He majored in classics, but switched to chemistry in his junior year, obtaining his AB degree in 1909. Fisher then attended Columbia University on scholarship, earning his PhD degree in 1912 under Marston Taylor Bogert. His PhD dissertation focused on the preparation and properties of 5-aminoquinoline-6-carboxylic acid and related compounds.

Career 1912-1919 Instructor in Organic Chemistry at Columbia University 1919-1926 B. F. Goodrich, Akron, Ohio 1926-1936 Research Chemist at U. S. Rubber Company, New York and New Jersey 1936-1950 Director of Organic Research at U. S. Industrial Chemicals 1950 retired 1951-1952 Administrative Assistant for the National Research Council, special assistant to the director of the Office of Synthetic Rubber 1953 - Head, Department of Rubber Technology, University of Southern California

Recognitions Columbia University's Chandler Medal for his outstanding contributions to the chemistry of synthetic rubber 1949 Charles Goodyear Medal for outstanding achievement in the field of rubber chemistry

Worked examples

Example 1 — a first encounter with Harry L. Fisher

Start with the simplest possible case. Write down what Harry L. Fisher 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 Harry L. Fisher 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 Harry L. Fisher 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 Harry L. Fisher

In research: Harry L. Fisher 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 Harry L. Fisher 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: Harry L. Fisher is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1885 births, 1961 deaths, 20th-century American chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Harry L. Fisher 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.
