Reference excerpt

The statue of James Henry Greathead, designed by James Butler, is installed outside the Royal Exchange, where it conceals a ventilation shaft. It was erected in 1994 on a traffic island in the middle of Cornhill, London, with traffic passing to either side, similar to the statue of Prince Albert at Holborn Circus. The London Troops War Memorial is nearby.

Background James Henry Greathead was a South African born English civil engineer best known for his work on the railway lines now incorporated into the London Underground. Greathead was an engineer on the London (City) & Southwark Subway, later the City and South London Railway, and now part of the Northern line, which has a station near to the statue at Bank.

Description and history The bronze statue depicts a bearded Greathead wearing a broad-brimmed hat (an allusion to his South African origins) and carrying a coat over his right arm, holding a piece of paper which he is reading. It stands on a hollow oval Portland stone base with granite plinth. The base bears a bronze plaque on one side depicting a tunnelling shield with an inscription that credits Greathead as being the "inventor of the travelling shield that made possible the cutting of the tunnels of London's deep level tube system". (A part of the tunnelling shield used at Bank station was rediscovered during a refurbishment, and left visible painted red in a passageway leading to the Waterloo & City line.) The other side of the base bears the carved stone badge of the City & South London Railway. Visible in a gap between the statue and the base are the metal grilles of a vent shaft installed at Bank Junction to meet safety standards introduced after the King's Cross fire in 1987. The statute was unveiled by the Lord Mayor of London Sir Paul Newell on 17 January 1994.

Worked examples

Example 1 — a first encounter with Statue of James Henry Greathead, London

Start with the simplest possible case. Write down what Statue of James Henry Greathead, London claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Statue of James Henry Greathead, London 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 Statue of James Henry Greathead, London 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 Statue of James Henry Greathead, London

In research: Statue of James Henry Greathead, London appears in engineering 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 Statue of James Henry Greathead, London 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: Statue of James Henry Greathead, London is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1994 establishments in England, 1994 sculptures, Buildings and structures completed in 1994, so understanding it makes those chapters shorter.
In everyday life: Look for Statue of James Henry Greathead, London 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.
