Reference excerpt

John Brian Walker (1924 – 15 October 2014) was a British general practitioner with a prior career in eye surgery. After studying at New College, Oxford and while studying medicine at The London Hospital in 1945, he was one of the London medical students who were sent to Bergen-Belsen concentration camp shortly after its liberation by British troops, to assist in the feeding of the severely malnourished and dying inmates, under the supervision of nutritionist Arnold Peter Meiklejohn. After gaining his medical degree, he was drafted into the army and sent to east Africa, where he became an eye surgeon. Following demobilisation, he returned to London with his wife Mary and took on his father's general practice. Walker was also known for his skill in sailing with the Hornet dinghy fleet throughout the 1950s to 1970s.

Early life

John Brian Walker was born in Catford, London. After studying at New College, Oxford and while studying medicine at The London Hospital in 1945, he was one of the London medical students who were sent to Bergen-Belsen concentration camp shortly after its liberation by British troops, to assist in the feeding of the severely malnourished and dying inmates, under the supervision of nutritionist Arnold Peter Meiklejohn. After gaining his medical degree, he was drafted into the army and sent to east Africa, where he became an eye surgeon and married Mary, a Royal London Hospital nurse. Following the demobilisation of the British Armed Forces after the Second World War, he returned to London with Mary and ran his father's general practice. They had one son and a daughter.

Later life Walker was also known for his skill in sailing with the Hornet dinghy fleet throughout the 1950s to 1970s. With Mary, they ran a "cadet week" at Burnham-on-Crouch, Essex, to help young people learn to sail. They later had an Alan Buchanan 44 foot yacht built. It was launched in 1991 and they spent many summers sailing it around the Mediterranean.

Death On 15 October 2014, he died from congestive cardiac failure at home in Cornwall. Mary had died before him and his son died in 2011. On 1 November 2014, a memorial was held at the Harbour Club in Portscatho, Cornwall. He donated his body to a medical school for the study of anatomy. He was outlived by one daughter, Stefanie.

Worked examples

Example 1 — a first encounter with John Brian Walker

Start with the simplest possible case. Write down what John Brian Walker 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 John Brian Walker 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 Brian Walker 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 Brian Walker

In research: John Brian Walker 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 John Brian Walker 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 Brian Walker is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 births, 1945 in medicine, 2014 deaths, so understanding it makes those chapters shorter.
In everyday life: Look for John Brian Walker 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.
