Reference excerpt

Sir William MacGregor Henderson FRS FRSE MRCVS (17 July 1913 – 29 November 2000) was a Scottish veterinary expert on foot and mouth disease. He was also President of the Zoological Society of London, 1984–1989. He was in charge of controlling foot and mouth disease in South America from 1957 to 1966. In his life he was generally called Gregor Henderson.

Life Henderson was born in Edinburgh, the son of William Simpson Henderson and his wife, Catherine Alice Marcus Berry. His father was managing director of the company which printed bank-notes for the Royal Bank of Scotland. They lived at 123 Dalkeith Road in the south of the city. He was educated at George Watson's College in Edinburgh. He studied at the Royal (Dick) Veterinary College in Edinburgh. During his career at the Animal Virus Research Institute at Pirbright, which he joined in 1939, Henderson developed an improved foot and mouth vaccine and developed a method of determining the virus content in a sample of infected material, which became known as the Henderson Method. He obtained his DSc from the University of Edinburgh in 1945 with a thesis entitled “The quantitative study of foot-and-mouth disease virus”. Henderson remained at Pirbright until 1956. From 1972 to 1978, he was Secretary of the Agricultural Research Council. He was knighted in 1976. Henderson was elected as a Fellow of the Royal Society in 1976 and a Fellow of the Royal Society of Edinburgh in 1977. His proposers for the latter were Sir William Weipers, Sir John N Ritchie, Sir Alexander Robertson, and Robert Comline. Following retirement he became the Director of London Zoo.

Family In 1941 he married Alys Beryl Goodridge; they had four sons.

Worked examples

Example 1 — a first encounter with William MacGregor Henderson

Start with the simplest possible case. Write down what William MacGregor Henderson claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 William MacGregor Henderson 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 William MacGregor Henderson 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 William MacGregor Henderson

In research: William MacGregor Henderson appears in biology 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 William MacGregor Henderson 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: William MacGregor Henderson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 2000 deaths, Alumni of the University of Edinburgh, so understanding it makes those chapters shorter.
In everyday life: Look for William MacGregor Henderson 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.
