A packed Library was welcomed by Mr. Roland Machin, who introduced Mr. Ian Doughty from Congleton Museum with a talk illustrated by slides on the local polymath Mr. John Whitehurst.
Born on the April 10th 1713 he was the eldest son of John Whitehurst who was a clock maker and prominent citizen of Congleton. John Whitehurst (Senior) held many local positions in the town and also founded a successful clock-making business. His father also fostered an interest in geology when taking him for long walks in the Derbyshire Peak District. He was also interested in the sources of copper, an essential mineral for the brass used in clocks and heavier bearings as many brass founders had to move premises as local sources were depleted.
One of the first questions Mr. Ian Doughty asked was “Why didn’t John take over the family business in Congleton letting his younger brother James run the firm?” Instead, he set up in Derby about 1736 where he presented a turret clock to the corporation for installation in the new Guildhall thus gaining his freedom to trade as a burger living and working in Iron Gate. He married Elizabeth Gretton in 1745 and worked as Church Warden of All Saints in 1761-62 and continued to live in Derby until 1780.
He was one of the foremost scientists of his day, father of modern geology and founder member of the Lunar Society along with Erasmus Darwin, Josiah Wedgewood, James Watt and others (see below). This raised Mr. Doughty’s second question “Why did so many young men from the Midlands become the Elite of the Age?” Closely followed by a third question “Why did the Lunar Society feature so many men we can describe as polymaths?” As a clock maker and engineer, Whitehurst’s innovations included the round dial long case clock, a standardisation of parts and the manufacture of components to very high tolerances. He also made compasses, way-wisers, timers for pottery kilns, pyrometers and barometers. One of Whitehurst’s most important achievements was in geology; in 1763, he sent Benjamin Franklin (an occasional visitor to his Derby house) an outline of his theory on the origin and formation of the earth, which was later published.

The links to other members of the Lunar Society can be seen from his inventions. His work on strata facilitated the prospecting and mining of minerals such as coal, lead and copper and he had a stake in the extraction operations of Anthony Tissington, proprietor of a very prosperous mining company which owned mines not only in Derbyshire but also in Yorkshire, Durham and Scotland.
Another area of further research which can be added to the first three questions is “Why do the Cheshire families have such strong links to Ireland?” It is believed, for example, that between leaving Congleton and setting up in Derby John worked in Ireland probably with the Parnell family.
In 1799 John Whitehurst was elected as a Member of the Royal Society, which was given its Charter by Charles II in 1666 and he obtained the position of Stamper of the Money Weights at the Royal Mint under an Act of 1780, finally leaving Derby for London. He died in 1788 leaving his property and clock making business to his nephew, John Whitehurst young son of his brother James who had succeeded to his father’s firm in Congleton. In a sense this closed a circle back to his roots.
John Whitehurst was a founder member of the Lunar Society which met on the first Monday after the full moon so there was moonlight for the journey home across the rutted roads. The Lunar Society would meet in Birmingham and become the main intellectual powerhouse of the Industrial Revolution in England. So who were some of the other members of the Lunar Society?

1. Matthew Boulton, FRS (September 3rd 1728 – August 17th 1809) was an English manufacturer and business partner of Scottish engineer James Watt. In the final quarter of the 18th century the partnership installed hundreds of Boulton & Watt steam engines, which were a great advance on the state of the art, making possible the mechanisation of factories and mills. Boulton applied modern techniques to the minting of coins, striking millions of pieces for Britain and other countries, and supplying the Royal Mint with up-to-date equipment.
2. Erasmus Darwin, who wrote “A fool you know, is a man who never tried an experiment in his life” was one of the greatest polymaths. George III asked him to be his personal physician but he declined, preferring to stay where he had settled in Lichfield, Staffordshire.
3. Thomas Day of London was educated at Corpus Christi College, Oxford from the age of 16 where he met Richard Lovell Edgeworth, during a vacation. They were influenced by the work of philosopher Jean-Jacques Rousseau, who denounced corruption and endeavoured to return to the simplicity of nature. Although Day studied law and was called to the bar in 1775 he never practiced. He spent his life as a philanthropist, writer and political essayist.
4. Benjamin Franklin was one of the Founding Fathers of the United States. A noted polymath. He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and the glass armonica. He formed both the first public lending library in America and the first fire department in Pennsylvania. He also had time to visit England and attend a meeting of the Lunar Society.
5. Samuel “John” Galton Jr. FRS was born in Duddeston, Birmingham and despite being a Quaker he was an arms manufacturer and lived at Great Barr Hall.
6. Richard Lovell Edgeworth born in Bath in Somerset and died at Edgeworthstown, County Longford, Ireland. An Anglo-Irish inventor his mechanical inventions included possibly the first attempt at telegraphic communication, the creation of various sailing carriages, a velocipede (cycle), a perambulator (land measuring machine), a turnip cutter, a one-wheeled chaise, and a phaeton (a four-wheeled open carriage). Edgeworth also wrote Practical Education (1798), written in collaboration with his daughter, which argued that children should be given a strong motive to learn and that the pace should be adjusted to the child’s age and ability discouraging learning by rote. Four times married, Edgeworth had 22 children!
7. William Murdock was born in Old Cumnock near Ayr and died in Birmingham. A Scottish inventor, the first to make extensive use of coal gas for illumination and a pioneer in the development of steam power. He worked for the engineering firm of Matthew Boulton and James Watt in their Soho works at Birmingham. In Cornwall to superintend the fitting of Watt’s steam engines he experimented in distilling coal and in 1792 lighted his cottage and offices with coal gas. Returning to Birmingham about 1799, he perfected further practical methods for making, storing, and purifying gas. He also made important improvements in the steam engine including and various modifications to the arrangements of shafts and flywheel. He experimented with compressed air and in 1803 constructed a steam gun and he retired from business in 1830.
8. Joseph Priestley was one of the most remarkable thinkers of the 18th century. Best known today as the scientist who discovered oxygen, he also made major contributions in the fields of education, politics, philosophy, and theology.
9. William Small was born in Forfarshire, Scotland in 1734 and attended Marischal College, Aberdeen and was awarded his MD in 1765. At the age of 23 he was appointed Professor of Natural Philosophy at William and Mary College, Virginia, then one of Britain’s American colonies. One of his students was Thomas Jefferson. In 1764 Small returned to Britain armed with a letter of introduction to Matthew Boulton from Benjamin Franklin where he established a medical practice in Birmingham. Between 1765 and 1775 he acted as Boulton’s doctor and became a close friend of other members of the Lunar Society. His knowledge of mathematics, mechanics and chemistry provided him with an important intellectual role, advising on the development of the steam engine, engaging in chemical experiments alongside Boulton and Keir and designing clocks. He also involved himself in cultural activities helping to bring the Theatre Royal to Birmingham in 1774.
10. James Watt was sent to Glasgow to learn the trade of a mathematical-instrument maker and established his business there. He developed a reputation as a high quality engineer and was employed on the Forth & Clyde Canal and the Caledonian Canal. In 1763 Watt was sent a Newcomen steam engine to repair and noted a way of making it more efficient. He sought a partner with money and asked John Roebuck to provide financial backing for the project and went into partnership with him.
11. Josiah Wedgwood was an English potter, founder of the Wedgwood company, credited with the industrialization of the manufacture of pottery. A prominent abolitionist, Wedgwood is remembered for his “Am I Not A Man And A Brother?” anti-slavery medallion. He was a member of the Darwin-Wedgwood family and grandfather of Charles and Emma Darwin.
12. William Withering was born in Wellington, Shropshire, trained as a physician and studied at the University of Edinburgh. He worked at Birmingham General Hospital from 1779. He treated a patient with dropsy (swelling from congestive heart failure) and noted the remarkable improvement that the taking of a traditional herbal remedy had. He identified that the active ingredient in the mixture came from the foxglove plant now known as digitalis, after the plant’s scientific name. In 1785 he published An Account of the Foxglove and some of its Medical Uses.

The links between all these men point to a joint interest in medicine, manufacturing and geology and the use of the most accurate measurements possible. For example, as Mr. Doughty stated, when Mr. Wedgwood was inventing glazes the temperature of firing is critical and Mr. Whitehurst could provide an accurate measurement.
Mr. Doughty answered a number of questions before the Meeting Chairman, Mr. Roland Machin, thanked him on behalf of the audience for such an interesting talk.
