Norman Allinger

Norman Allinger 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 Norman Allinger rather than just read about it. In short: Norman "Lou" Allinger (6 April 1928 – 8 July 2020) was an American organic and computational chemist and Distinguished Research Professor Emeritus of Chemistry at the University of Georgia (UGA) in Athens. Lou Allinger was the elder of two children of Norman Clark Allinger (a bank employee) and Florence Helen (née Young).

Key takeaways

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

Reference excerpt

Norman "Lou" Allinger (6 April 1928 – 8 July 2020) was an American organic and computational chemist and Distinguished Research Professor Emeritus of Chemistry at the University of Georgia (UGA) in Athens. Lou Allinger was the elder of two children of Norman Clark Allinger (a bank employee) and Florence Helen (née Young). He was born in Alameda, California. His mother died, aged 75, on 3 January 1982. His father died on 3 July 1983, aged 82. “From the age of nine on he was always employed in some fashion, first at the age of nine selling magazines and newspapers, then later as an ice-man, a part-time mail carrier, an apricot-picker, a butcher’s apprentice, and a warehouseman, loading tin cans onto railway cars”. Allinger always had an interest in science, starting with astronomy at age 9 and pursuing that hobby with friends for many years, including his college years when he assembled a 6-inch Newtonian reflector using lenses he had ground himself. He began chemistry as a hobby around 10 or 11 and won a Boy Scout merit badge in the subject at age 13. Aged 17, Allinger was experimenting with a highly dangerous mixture of magnesium and red phosphorus with three teenage friends in his bedroom at home. It resulted in an explosion which severely injured one friend. Lou escaped with "multiple cuts about the face and upper body". Allinger attended Alameda High School and then, aged 18, he enlisted in the US Army, and was stationed in Fairbanks, Alaska. After his term of enlistment Allinger attended the University of California, Berkeley, from where he graduated with a BS in chemistry in 1951. For his PhD he moved to University of California, Los Angeles, to work with Donald J. Cram. He was awarded the degree in 1954. Allinger then crossed the country to Harvard, where he worked with Paul Bartlett. In 1956 Allinger joined the faculty of Wayne State University, becoming a full professor of chemistry in 1960. After thirteen years in Detroit he moved to the University of Georgia as Research Professor. Allinger became the founding editor of the Journal of Computational Chemistry, the first issue of which appeared in 1980. “Professor Allinger is honored for his pioneering work in computational chemistry, his seminal contributions to the development of the molecular mechanics series of force fields, their widespread application to the fundamental understanding of molecular structure and energetics, and their implementation as a significant tool for practicing chemists”. He was the senior author of the MM2, MM3, and MM4 molecular mechanics software packages. Allinger published more than 360 papers in his career.

Away from chemistry, Lou Allinger was a jazz musician, pianist and tenor banjo player, who performed at “jazz dives” for more than six decades. He appeared in two albums with the band Sundown Stompers”. He retired from playing music in 2008. Allinger was a philatelist with a very large worldwide collection of used stamps. "For the last ten years of his life, Lou would show up in the lab at 7 AM. At noon or a bit later, he would go home to have lunch with his wife. Thereafter, he would work on his stamp collection for an hour or two, followed by an afternoon nap." He was also a lifetime lover of baseball, supporting the Atlanta Braves fan once he had moved to Georgia; and a life long champion of the Boy Scout movement. Before his funeral the family requested that, in lieu of flowers, donations be made in Dr. Allinger’s name to the Boy Scouts of America.

Family Norman Louis Allinger married Janet Waldron on 14 August 1952 in Los Angeles. They published a paper on conformational analysis in 1960 and several thereafter. They had four children the first of whom, Gregory Edward, died at birth on 7 January 1962 in Detroit. The others were Ilene Suzanne, James Augustus and Alan Louis, all of whom survived their father. Janet Waldron Allinger, who was born in Georgia, died in Athens in 1991, aged 62. Lou married Irene Saez in 1992, whose three children all survived their stepfather. Norman Louis Allinger died in Athens on 8 July 2020. Lou and Janet are buried at Athens Memory Gardens in Georgia.

Worked examples

Example 1 — a first encounter with Norman Allinger

Start with the simplest possible case. Write down what Norman Allinger 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 Norman Allinger 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 Norman Allinger 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 Norman Allinger

In research
Norman Allinger 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 Norman Allinger 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
Norman Allinger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2020 deaths, Alameda High School alumni, so understanding it makes those chapters shorter.
In everyday life
Look for Norman Allinger 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.
