[1] In 1850, Vaughan and his mining geologist John Marley discovered iron ore, conveniently situated near Eston in the Cleveland Hills of Yorkshire.
[4] Unknown to anyone at the time, this vein was part of the Cleveland Ironstone Formation, which was already being mined in Grosmont by Losh, Wilson and Bell.
[citation needed] To make use of the ore being mined at Eston, Bolckow and Vaughan built a blast furnace in 1851 at nearby South Bank, Middlesbrough, enabling the entire process from rock to finished products to be carried out in one place.
The Institution of Civil Engineers, in their obituary, commented on the relationship between Vaughan and Bolckow: "There was indeed something remarkable in the thorough division of labour in the management of the affairs of the firm.
Richards' work helped to improve the Bessemer process for making steel, in the case when the ore is rich in phosphorus, and an alkaline rock (dolomite, limestone or magnesite) is used.
[8] In 1877, the Eston Ironworks acquired a rolling mill engine from the Vulcan Iron Works of Thwaites and Carbutt, Bradford.
[11] On 2 June 1884, Sir Joseph Pease unveiled a monument to John Vaughan in Exchange Square, Middlesbrough, which still stands.
He gave a speech to the crowd of 15,000 people, in which he described the town as "the greatest iron-producing district in the world", and compared Bolckow and Vaughan to the mythical founding fathers of Rome, Romulus and Remus.
Bolckow, Vaughan's women workers were runners-up in a replayed final tie for the Tyne Wear & Tees Alfred Wood Munition Girls Cup.
The former extent of the Bolckow, Vaughan property at the Eston Sheet and Galvanizing Works beside the River Tees Dockyard is still marked by boundary stones on Smiths Dock Road, Middlesbrough.
[22] The graves of the founding fathers of the company and of Middlesbrough, Henry Bolckow and John Vaughan, in St Cuthbert's Churchyard, Marton, fell into disrepair.
