Reference excerpt

John Henry Gurney Jr. (31 July 1848 – 8 November 1922) was a British ornithologist from the Gurney family.

Family origins Gurney was born in 1848 in Easton Lodge, Easton, Norfolk, son of John Henry Gurney Sr. and his second cousin Mary Jary Gurney. He was educated at Harrow School.

Career For a short time Gurney worked in Messrs. Backhouse's bank at Darlington, but he spent most of his life in Norfolk. In Norfolk he was known as a landowner and country gentleman. He took a prominent part in local religious and philanthropic work. He was High Sheriff of Norfolk in 1894. At the time of his death he was a Justice of the Peace and a Deputy Lieutenant for Norfolk.

Ornithologist His father, John Henry Gurney Sr, although a politician was probably best known as an ornithologist, therefore John Henry junior was brought up from an early age to know and love birds. Gurney gained an international reputation as an ornithologist. He was elected as a Fellow of the Zoological Society in 1868, a Member of the British Ornithologists' Union in 1870 and a fellow of the Linnean Society in 1885. Gurney also took a keen interest in local ornithology. He was always a generous supporter of the local Wild Birds' Protection Societies. He was one of the original members of the Norfolk and Norwich Naturalists' Society which was founded in March 1869.

Marriage and family John Henry Gurney married Margaret Jane Gurney (1851-1940) on 25 October 1876 at St Marylebone church, Westminster, London. Margaret was also his second cousin, daughter of Henry Edmund Gurney (1821-1905) and Jane née Birkbeck (1828-1888). They had a son and three daughters:

Gerald Hudson Gurney (1880-1934) Agatha Gurney (1881-1937) Cecily Jane Gurney (1884-1958) Margaret Editha Gurney (1886-1981)

Works Gurney's first written contribution to ornithology was a letter to The Ibis on swallows which was published in 1866. His most important publications include:

Worked examples

Example 1 — a first encounter with John Henry Gurney Jr.

Start with the simplest possible case. Write down what John Henry Gurney Jr. claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 John Henry Gurney Jr. 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 John Henry Gurney Jr. 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 John Henry Gurney Jr.

In research: John Henry Gurney Jr. appears in science 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 John Henry Gurney Jr. 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: John Henry Gurney Jr. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1848 births, 1922 deaths, British ornithologist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for John Henry Gurney Jr. 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.
