Reference excerpt

Lewis Llewelyn Dillwyn (19 May 1814 – 19 June 1892) was a Welsh industrialist and Liberal politician who served as MP for Swansea for 37 years.

Early life Dillwyn was born in Swansea, Wales, the fourth of six children of Lewis Weston Dillwyn and Mary Dillwyn. He had two brothers and three sisters. His grandfather, William Dillwyn, was an American Quaker, who, alongside others such as William Wilberforce had campaigned for the abolition of the slave trade. His father had been sent to Swansea by his father William, to take over the management of the Cambrian Pottery, and lived at Sketty Hall. He was educated at Kilvert's Academy in Bath but, following his father's election to Parliament as one of the two members for Glamorgan in 1832 he and chose to follow a business career by taking over the management of Cambrian Pottery, rather than enter Oriel College, Oxford as had been intended. His father was a friend of the geologist Henry De la Beche and Dillwyn and De la Beche carried out experiments on china clays and granites with the aim of improving the production of earthenware. On 16 March 1838, Dillwyn married de la Beche's daughter Elizabeth and, with his wife's artistic guidance, the pottery produced a range of beautiful Etruscan ware which is today a collector's item. They had four children, the best known of whom was Amy Dillwyn, and lived at the newly built Hendrefoilan House in Sketty.

Industrial activities Dillwyn followed his father and his Quaker antecedents in pursuing industry and commerce and radical politics, and played a major part in the industrial development of Swansea. He was head of the firm of Dillwyn and Richards at the Landore spelter works and began to expand his industrial activities to include silver refining. Later, he formed a partnership with William Siemens to establish the Landore Siemens Steel Co., and by 1874 this company had become one of the four largest producers in the world, employing some 2000 workers. In the 1880s, following a slump in the steel industry, Dillwyn concentrated his manufacturing activities on his spelter works at Llansamlet (equally in the built-up area of Swansea), and soon became one of the major zinc producers in the country. Dillwyn was also for many years an active director of the Great Western Railway and Chairman of the Glamorganshire Banking Co.

Military connections In 1859 he raised the 3rd (Swansea Rifles) Glamorganshire Rifle Volunteers and was commissioned as their Captain. The Swansea Rifles grew to become a full battalion. Dillwyn continued to command the unit (which was often known as 'Dillwyn's') for many years, rising to Lieutenant-Colonel Commandant in 1877 and full Colonel in 1888. In 1881, while inspecting the troops after they had completed a week's training he fell from his horse and sustained serious injuries from which he did, however, recover.

Worked examples

Example 1 — a first encounter with Lewis Llewelyn Dillwyn

Start with the simplest possible case. Write down what Lewis Llewelyn Dillwyn 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 Lewis Llewelyn Dillwyn 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 Lewis Llewelyn Dillwyn 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 Lewis Llewelyn Dillwyn

In research
Lewis Llewelyn Dillwyn 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 Lewis Llewelyn Dillwyn 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
Lewis Llewelyn Dillwyn is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1814 births, 1892 deaths, Dillwyn family, so understanding it makes those chapters shorter.
In everyday life
Look for Lewis Llewelyn Dillwyn 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.
