Lunar Society of Birmingham (c. 1765): Science Meets Industry

The Lunar Society of Birmingham was an informal club of scientists, inventors and manufacturers that met in the English Midlands from about 1765 until the early 19th century. Its members, including Matthew Boulton, James Watt, Erasmus Darwin, Josiah Wedgwood and Joseph Priestley, combined scientific curiosity with practical business. The society is often seen as a symbol of the links between the Enlightenment and the Industrial Revolution.

Origins

Birmingham in the mid-18th century was a fast-growing town of metalworkers, without a university or an old corporation. Its industries made buttons, buckles, toys, guns and brass goods, and its manufacturers were open to new techniques.

The society grew from friendships around Matthew Boulton, a Birmingham manufacturer of metal goods who built the Soho Manufactory from 1765–1766, and the physician and poet Erasmus Darwin of Lichfield. A key early figure was William Small, a Scottish doctor who had taught natural philosophy at the College of William & Mary in Virginia, where Thomas Jefferson was among his pupils. Small came to Birmingham in 1765 with an introduction from Benjamin Franklin, who knew Boulton and Darwin.

By the late 1760s these men, with friends such as the clockmaker John Whitehurst of Derby, met regularly. More formal monthly meetings, and the name “Lunar Society”, date from about 1775.

Meetings and members

Members met on the Monday nearest the full moon, so that they had light to ride home after dinner. They gathered in members’ homes, especially Boulton’s Soho House in Handsworth, and called themselves “Lunarticks”. The society had no rules, minutes or publications, which is why its history must be reconstructed from letters.

Its core membership, usually counted at about 14, included:

• Matthew Boulton, manufacturer and Watt’s business partner.
• James Watt, the Scottish engineer, who moved to Birmingham in 1774.
• Erasmus Darwin, doctor, inventor and poet, grandfather of Charles Darwin.
• Josiah Wedgwood, the Staffordshire potter.
• Joseph Priestley, chemist and Dissenting minister, who joined after moving to Birmingham in 1780.
• William Withering, physician and botanist.
• James Keir, chemist and glass and chemical manufacturer.
• Richard Lovell Edgeworth and Thomas Day, inventor and author respectively.
• Samuel Galton Jr., a Quaker gun manufacturer, and others, including William Small, John Whitehurst, Jonathan Stokes and Robert Augustus Johnson.

Science and industry

Conversation ranged widely: electricity, chemistry, geology, botany, medicine, canals, education and politics. Members tested each other’s ideas, lent apparatus and shared contacts and capital.

The most famous result was the partnership between Boulton and Watt. Boulton took over a share of Watt’s patent for an improved steam engine, and from 1775 the two produced engines at Soho, first for pumping water from mines and later for driving machinery.

Priestley carried out much of his research on gases in Birmingham, supported in part by subscriptions from fellow members, and Wedgwood helped supply him with apparatus. Withering published his study of the foxglove in 1785, introducing digitalis as a treatment for heart conditions. Wedgwood developed a pyrometer to measure the high temperatures of his kilns, for which he was elected a Fellow of the Royal Society in 1783. Darwin wrote long scientific poems, such as The Botanic Garden, and Zoonomia (1794–1796), which contained early ideas about evolution.

Politics and decline

Many members supported reform and were sympathetic to the American and early French revolutions. Several opposed slavery: Wedgwood produced the famous anti-slavery medallion of 1787 for the Society for the Abolition of the Slave Trade, and Day wrote an early anti-slavery poem, The Dying Negro (1773, with John Bicknell).

These views made enemies. On 14 July 1791, after a dinner celebrating the anniversary of the fall of the Bastille, rioters in Birmingham attacked Dissenters’ chapels and homes. Priestley’s house and laboratory were destroyed, and he later emigrated to the United States in 1794. The Priestley Riots, combined with the ageing and death of its founders, ended the society’s most active period. It was formally wound up in 1813.

Legacy

The Lunar Society showed how a small group of curious, practical people outside the universities could advance both knowledge and industry. Historians such as Robert Schofield and Jenny Uglow have made it a classic case study of the provincial Enlightenment. In Birmingham the members are remembered by the “Moonstones”, a set of stone memorials, and by Soho House, now a museum.

Timeline

• 1765: William Small settles in Birmingham; informal meetings with Boulton and Darwin begin around this time.
• 1766: Boulton moves into Soho House, beside his new Soho Manufactory in Handsworth.
• 1774: James Watt moves to Birmingham.
• 1775: The Boulton and Watt partnership begins; regular monthly “Lunar” meetings date from about this year.
• 1780: Joseph Priestley moves to Birmingham and joins the society.
• 1785: William Withering publishes his account of the foxglove.
• 1791, 14 July: The Priestley Riots destroy Priestley’s home and laboratory.
• 1813: The society is formally dissolved.

Why it matters

The Lunar Society connected scientific experiment with manufacturing, medicine and social reform at a moment when Britain was beginning to industrialise. Its members’ friendships produced some of the key inventions and ideas of the age, and the society remains a model of how informal networks can drive innovation.
