Benjamin Huntsman

• 1. Introduction

  ›

  Benjamin Huntsman was born on the 4th of June 1704 in Epworth, Lincolnshire, the fourth child of a Quaker farming couple named William and Mary Huntsman. What that boy from a modest farming household would go on to do changed the nature of steel itself. How does a clockmaker from Doncaster crack a metallurgical puzzle that had stumped ironworkers for generations? And why, when he finally solved it, did the very people who stood to benefit most refuse to touch his invention? Those are the questions at the heart of Huntsman's story.

• 2. The Clockmaker's Curiosity

  ›

  Huntsman set himself up in Doncaster, Yorkshire, making clocks, locks, and tools. His skill built a reputation that extended well beyond the workshop bench. Customers began consulting him as a surgeon in an experimental capacity, and he was also sought out as an oculist. For a man making his living from precision instruments, steel quality was not an abstract concern. The steel available in England at the time was inconsistent, and for a clockmaker it mattered enormously. That practical frustration is what drove Huntsman toward the furnace.

• 3. Solving Steel

  ›

  Huntsman began his steel experiments in Doncaster, then in 1740 moved to Handsworth, near Sheffield, to continue the work. After many trials he arrived at a process using clay pot crucibles, each holding about 34 pounds of blistered steel. A flux was added, the pots were covered, and coke heat was applied for roughly three hours. The molten steel was then poured into moulds, and the crucibles were cleaned and used again. The first object ever made from crucible cast steel was a longcase clock built by Huntsman himself. That clock now sits in the Enid Hattersley Gallery at Kelham Island Museum.

• 4. Refusal, Export, and Reversal

  ›

  Sheffield's cutlery makers had a problem with Huntsman's product: it was harder than the German steel they already knew how to work. Rather than adapt, they simply refused to buy it. Huntsman responded by shipping his entire output to France, where manufacturers were glad to take it. The irony arrived when French cutlery made from that same Sheffield cast steel began flowing back into the English market. Alarmed by the competition they had helped create, the Sheffield cutlers tried to persuade the British government to ban the export of Huntsman's steel. That effort failed. Faced with the threat to their own trade, the cutlers were compelled to start using the material themselves.

• 5. The Secret Stolen

  ›

  Huntsman never patented his crucible process. That decision left him exposed. A Sheffield iron-founder named Walker discovered the method, and the story attached to that discovery became legend. Walker, it was said, entered Huntsman's works dressed as a starving beggar, asking only to sleep by a fire for the night. From that vantage point, he watched enough of the operation to reconstruct it. Whether the account is precisely true, the result was real: the process spread beyond Huntsman's control.

• 6. Later Years and Legacy

  ›

  In 1770 Huntsman relocated his operation to Worksop Road in Attercliffe, a move that proved profitable. He worked there until his death on the 20th of June 1776, and was buried with a commemorative tomb at Hilltop Cemetery on Attercliffe Common. His son William Huntsman, born in 1733 and living until 1809, took over the business. Sheffield has marked his place in the city in two ways: one of the original main buildings at the city's Northern General Hospital carries his name, and a public house in the city centre trades under the name The Benjamin Huntsman.
