The Peak District’s proximity to the industrial cities brought many of the great steel masters to the area. Charles Cammell of Cammell Laird, armour-plate manufacturers lived at Brookfield Manor in Hathersage and is buried in the churchyard there. Joseph Whitworth of screw thread fame lived at Darley Dale and is buried in the churchyard of St Helen’s.
One of the major steel makers in Sheffield was the company of Thomas Firth, a major armaments manufacturer and the supplier of high-grade steel to Samuel Colt in Connecticut USA, for his gun barrels. Thomas firth and his son Mark are buried in Sheffield, but other offspring reside in the churchyard of St Peter’s in Hope, their twin graves facing the city of Sheffield.
