Nelson (cat)

Nelson (cat) is a science 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 Nelson (cat) rather than just read about it. In short: Nelson (fl. May 1940 – May 1944) was a cat who served as the chief mouser to the Cabinet Office during the wartime coalition government as a pet of Winston Churchill.

Key takeaways

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

Reference excerpt

Nelson (fl. May 1940 – May 1944) was a cat who served as the chief mouser to the Cabinet Office during the wartime coalition government as a pet of Winston Churchill. In the summer of 1940, after Churchill became the prime minister, Nelson moved from Admiralty House to 10 Downing Street, where he had a rivalry with his predecessor: Neville Chamberlain's cat, the Munich Mouser.

Life and career

Winston Churchill decided to adopt Nelson, a black stray, when he witnessed him chasing off a "huge dog" from Admiralty House, London. Impressed by his bravery, Churchill named the cat after the British admiral Horatio Nelson, 1st Viscount Nelson. Following Churchill's appointment as prime minister in 1940, Nelson moved into 10 Downing Street from Admiralty House sometime during the summer. Opponents of Churchill speculated that he would not bring Nelson to Downing Street, suggesting that Churchill did not like cats; this was refuted by Churchill's friends as a "gross aspersion". Commenters also wondered whether Nelson and the previous prime minister Neville Chamberlain's cat, nicknamed the Munich Mouser, would get along:

How, it is asked, will the "Munich" cat react to "Nelson"? Will it follow Mr. Chamberlain next door to his new home at No. 11, leaving the field at No. 10 to "Nelson"? Or will it refuse to abdicate and call for a showdown in his majesty's court of justice? The cats did not take a liking to one another, with the rivalry between the pair later compared with that of the 21st-century mousers Larry and Palmerston. Churchill would reportedly regularly entertain guests with stories of Nelson's bravery. During the Christmas season of 1941 the United States gifted Churchill a large number of items, including catnip for Nelson. In February 1942 Quentin Reynolds, an American journalist, reported that Nelson had demonstrated his "faithfulness" to Churchill by jumping into his lap when called; Churchill's daughter Mary claimed that "Nelson isn't really that faithful", and "he [was] only being nice" to Churchill because they were to have salmon for lunch. Reynolds also described a dinner with the Churchills and Nelson in a book published that year, at which Churchill recited parts of Shakespeare's Hamlet. On 2 May 1944, at the Commonwealth Prime Ministers' Conference, Nelson was trapped in a fridge whilst attempting to get "an extra helping of milk", but was soon released unharmed. During meetings with Churchill's war cabinet, Nelson would sit close to Churchill, acting as a "prime ministerial hot water bottle"; the prime minister was reported to have mentioned this fact to Rab Butler, stating that through his acts Nelson "save[d] fuel and power", and thereby aided the war effort.

Worked examples

Example 1 — a first encounter with Nelson (cat)

Start with the simplest possible case. Write down what Nelson (cat) 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 Nelson (cat) 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 Nelson (cat) 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 Nelson (cat)

In research: Nelson (cat) 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 Nelson (cat) 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: Nelson (cat) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chief mousers to the Cabinet Office, Individual cats in England, so understanding it makes those chapters shorter.
In everyday life: Look for Nelson (cat) 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.
