Benjamin Huntsman
Benjamin Huntsman was born on the 4th of June 1704 in Epworth, Lincolnshire. He was the fourth child of William and Mary Huntsman, a farming couple who identified as Quakers. Some historical accounts suggest his parents were German immigrants, though other sources indicate they were both born within Lincolnshire itself. His early career began not with steel but with precision instruments. He established a business making clocks, locks, and tools in Doncaster, Yorkshire. This trade gave him enough reputation to practice surgery in an experimental fashion. He also worked as an oculist, consulting on eye conditions for local residents.
Huntsman moved his operations to Handsworth near Sheffield in 1740 to pursue experiments in steel manufacture. He developed a method using clay pot crucibles that held about one pound of blistered steel each. A specific flux was added to the mixture before the pots were covered. Workers heated the sealed containers using coke furnaces for approximately three hours. The resulting molten steel poured into moulds formed the final product. These heavy clay vessels could be reused after cooling. The first object crafted from this new cast steel was a longcase clock made by Huntsman himself. That clock now sits on display in the Enid Hattersley Gallery at Kelham Island Museum.
Local cutlery manufacturers in Sheffield refused to purchase the new material initially. They found it harder than the German steel they had used for years. This resistance forced Huntsman to export his entire output to France instead. The decision proved financially viable despite the distance. Competition from imported French cutlery eventually alarmed the Sheffield makers. They tried unsuccessfully to get the British government to prohibit the export of the steel. Self-preservation finally compelled them to adopt the material. The local industry realized they needed the superior quality to survive against foreign rivals.
Huntsman never patented his process, leaving the method open to observation and theft. His secret was discovered by a Sheffield iron-founder named Walker. According to legend, Walker entered Huntsman's works disguised as a starving beggar. He asked permission to sleep by a fire for the night. This ruse allowed him to observe the heating process inside the furnace. The story remains folklore without verified historical documentation. No written record confirms the exact details of how the secret was stolen. The lack of legal protection meant others could replicate the technique once they understood it.
In 1770, Huntsman moved his enterprise to Worksop Road in Attercliffe Common. He prospered at this new location until his death on the 20th of June 1776. A commemorative tomb marks his resting place in the Hilltop Cemetery at Attercliffe Common. The business passed directly to his son William Huntsman who lived from 1733 to 1809. Modern recognition includes a main building at Sheffield's Northern General Hospital bearing his name. A Wetherspoons pub in the city centre also carries his name today. These tributes ensure his contribution to metallurgy remains visible in the region.
