George Gray (chemist)

George Gray (chemist) 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 George Gray (chemist) rather than just read about it. In short: George William Gray (4 September 1926 – 12 May 2013) was a Professor of Organic Chemistry at the University of Hull who was instrumental in developing the long-lasting materials which made liquid crystal displays possible. He created and systematically developed liquid crystal materials science, and established a method of practical molecular design.

Key takeaways

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

Reference excerpt

George William Gray (4 September 1926 – 12 May 2013) was a Professor of Organic Chemistry at the University of Hull who was instrumental in developing the long-lasting materials which made liquid crystal displays possible. He created and systematically developed liquid crystal materials science, and established a method of practical molecular design. Gray was recipient of the 1995 Kyoto Prize in Advanced Technology.

Education and career Born in Denny, Scotland, Gray was educated at the University of Glasgow and while working as an assistant lecturer at the University College in Hull (then part of the University of London) obtained his PhD in 1953. He developed his academic career at the college, which became the University of Hull in 1954, from 1946 to 1990. He was appointed senior lecturer in 1960, Professor of Organic Chemistry in 1974, and GF Grant Professor of Chemistry in 1984. He remained an Emeritus Professor at Hull. In 1990 he joined the chemical company Merck, then became an independent consultant in 1996.

Liquid crystals

In 1973, in conjunction with the Royal Radar Establishment, Gray showed that 4-Cyano-4'-pentylbiphenyl possessed a stable nematic phase at room temperature. This compound and other long-lasting cyano-biphenyls made the twisted nematic display (LCD) popular. Gray wrote the first English book on liquid crystals, "Molecular Structure and Properties of Liquid Crystals", published in 1962. Gray was recipient of the 1995 Kyoto Prize in Advanced Technology and was made a Commander of the Order of the British Empire (CBE) in 1991. He was elected a Fellow of the Royal Society in 1983, and in 1987 was awarded the Leverhulme Medal of the Royal Society. In 1979 he was awarded the Rank Prize for Opto-electronics and in 1996 the SID Karl Ferdinand Braun Prize. The University of Hull was the first university to be awarded the Queen's Award for Technological Achievement, in 1979, for the liquid crystal joint-development work. Gray has been a Director of the International Liquid Crystal Society. Members of the British Liquid Crystal Society honoured his achievements by establishing the George W. Gray Medal for contributions to liquid crystal research and technology. In March 2013, the University of Hull celebrated the 40th anniversary of Gray's seminal paper being published on 22 March 1973. Hull Trains named their first British Rail Class 222 'Pioneer' high-speed train Professor George Gray in recognition of his achievements in the modern history of Hull.

Personal life In 1953 George Gray married Marjorie Canavan, who died two weeks before her husband. In later life they lived in Furzehill in Wimborne Minster, Dorset. They had three daughters.

Worked examples

Example 1 — a first encounter with George Gray (chemist)

Start with the simplest possible case. Write down what George Gray (chemist) 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 George Gray (chemist) 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 George Gray (chemist) 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 George Gray (chemist)

In research
George Gray (chemist) 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 George Gray (chemist) 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
George Gray (chemist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2013 deaths, 20th-century Scottish chemists, so understanding it makes those chapters shorter.
In everyday life
Look for George Gray (chemist) 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.
