Richard Crawshay was born in 1739 in Normanton in the West Riding of Yorkshire, the first child of William Crawshay (1713–1766), a farmer, and his wife, Elizabeth (1714–1774), née Nicholson. He had three sisters. According to family tradition a bitter quarrel with his father led to the sixteen-year-old Crawshay setting out for London.
Initially starting work aged 16, he was apprenticed to a Mr Bickleworth of York Yard, Thames Street, selling flat irons in an iron warehouse, he eventually became, on Bickleworth’s retirement in 1763, sole proprietor of the business, and by the 1770s he had established himself as one of London’s leading iron merchants.
He married Mary Bourne in 1763 and they had a son William and three daughters, Anne, Elizabeth and Charlotte. Charlotte married Benjamin Hall, and became the mother of Benjamin Hall, 1st Baron Llanover.
By 1775, he was acting as the agent for Anthony Bacon, owner of Cyfarthfa Ironworks, for supplying iron cannon to the Board of Ordnance, and in 1777 he became a partner in the business. In 1786, following the death of Anthony Bacon, he took over the whole Cyfarthfa Ironworks, in partnership with William Stevens (a London merchant) and James Cockshutt. In May 1787 he took out a licence from Henry Cort for his puddling process, but the rolling mill needed was not completed until 1789. He solved the problems of the puddling process by using an iron plate for the furnace ceiling and sea-washed sand for the floor. In 1791 he terminated the partnership, which had made little profit. He continued the business alone, and had two blast furnaces, eight puddling furnaces, three melting fineries, three balling furnaces, and a rolling mill in 1794. A blast furnace was built by 1796, and a fourth in 1796. There were six by 1810. He thus developed Cyfarthfa into one of the most important ironworks in South Wales.
Crawshay was very ambitious and imperious in manner, being called ‘The Tyrant’ by some, but was without social pretension. He was active in protecting the interests of the iron trade and was a major promoter of the Glamorganshire Canal which immensely improved transport of iron to Cardiff docks.
In 1804 Samuel Homfray the proprietor of the Penydarren Ironworks made a wager with Richard Crawshay of 500 guineas that Richard Trevithick’s steam locomotive could haul 10 tons of iron along the Merthyr Tramroad from Penydarren to Abercynon. Crawshay lost the bet when Trevithick’s became the first to haul wagons along a “smooth” iron road using adhesive weight alone.
At his death in 1810, Crawshay’s estate was worth £1.5 million. In his will he left three-eighths of the Ironworks to his son William Crawshay, three-eighths to his son-in-law Benjamin Hall and two-eighths to his nephew Joseph Bailey.
