About Inventor

Richard Lovell Edgeworth was an Anglo-Irish politician, writer and inventor.


Edgeworth was born in Pierrepont Street, Bath, England, great-grandson of Sir Salathiel Lovell through his granddaughter, Jane Lovell.

A Trinity College, Dublin and Oxford alumnus, he is credited for creating, among other inventions, a machine to measure the size of a plot of land. He also made strides in the developing educational methods. He anticipated the caterpillar track with an invention that he played around with for forty years but that he never successfully developed.He described it as a "cart that carries its own road".

He married Frances Beaufort, older sister of Francis Beaufort of the Royal Navy. The two men installed a telegraph line for Ireland.

Richard Lovell Edgeworth was a member of the Lunar Society. The Lunar Society evolved through various degrees of organization over a period of years, but was only ever an informal group. No constitution, minutes, publications or membership lists survive from any period, and evidence of its existence and activities is found only in the correspondence and notes of those associated with it. Dates given for the society range from sometime before 1760 to it still operating as late as 1813.

Fourteen individuals have been identified as having verifiably attended Lunar Society meetings regularly over a long period during its most productive time: these are Matthew Boulton, Erasmus Darwin, Thomas Day, Richard Lovell Edgeworth, Samuel Galton, Jr., James Keir, Joseph Priestley, William Small, Jonathan Stokes, James Watt, Josiah Wedgwood, John Whitehurst and William Withering.

Richard Edgeworth and his family lived in Ireland at his estate at Edgeworthstown, County Longford, where he reclaimed bogs and improved roads. He sat in Grattan's Parliament for St Johnstown (County Longford) from 1798 until the Act of Union in 1801, and advocated Catholic Emancipation and parliamentary reform. He was a founder-member of the Royal Irish Academy. He died in Edgworthstown on 13 June 1817.
