Overview
Jessop Saville & Company was a Sheffield-based British steelmaker formed in 1929 through the merger of two established local businesses: J.J. Saville and Company and William Jessop and Company. The company belonged to Sheffield’s long tradition of crucible steelmaking and subsequently developed a broader special-steel and alloy capability serving engineering, aerospace, energy, and other industrial markets. Its William Jessop predecessor traced its origins to the late eighteenth century. The business was originally associated with the Mitchell, Raikes and Jessop partnership and became William Jessop & Sons in 1832 when members of the Jessop family joined and expanded the operation. The company moved into the Brightside area of Sheffield and later added works at Kilnhurst. By the late nineteenth century its Brightside site had become a substantial industrial complex. The business was incorporated as a limited company in 1875, during the period when Sheffield’s specialist steel firms were adapting traditional crucible production to larger-scale industrial organization. J.J. Saville was another long-established Sheffield manufacturer, associated with crucible steel and file production at the Libau Works. The 1929 merger combined these two local histories into Jessop Saville & Company and gave the resulting enterprise a significant position in the production of specialist steels. During the twentieth century the company worked with alloy systems and materials intended for demanding technical applications rather than commodity steel markets. The company also explored international production. In the early twentieth century, pressure from fuel costs, United States tariffs, and growing American competition led Jessop’s management to examine the possibility of melting steel in the United States. Unlike some British producers, it did not regard production outside Britain as incompatible with the commercial value of the Jessop name. This illustrates the company’s effort to preserve access to overseas customers while responding to changing industrial economics. After the Second World War, Jessop developed research facilities at Whiston Grange near Rotherham. The site supported work on special steels, titanium, and titanium alloys, including research relevant to aerospace materials. The company’s laboratories were involved in early work on casting titanium and titanium alloys. In the mid-1960s, Sheffield’s steel industry began considering rationalization of its foundry capacity. Jessop Saville discussed combining foundry interests with Samuel Osborn, Edgar Allen and Company, and Hadfields Limited, but the proposed four-company arrangement did not proceed. Jessop’s foundry and melting interests were subsequently reorganized through arrangements involving Edgar Allen. In the late 1960s, Jessop Saville’s owner, BSA, sold its titanium interests to IMI. Jessop-developed alloys were incorporated into IMI’s materials portfolio, marking a transfer of part of the company’s specialist technology and business activity. The Brightside Lane works eventually closed in the late 1980s. After a period of vacancy, the former industrial site was redeveloped as an office and commercial area known as Jessop’s Riverside, preserving the historical name in Sheffield’s built environment. In February 1998, Special Melted Products Limited and Jessop Saville Limited were acquired by Allegheny Teledyne, a transaction associated with the value of their specialist melting and remelting operations. Jessop’s non-magnetic drill collars and downhole components were of particular interest because of their relevance to oil and gas drilling. The available historical material does not establish the company’s present standalone operating status, corporate structure, or whether the Jessop Saville name remains an active commercial brand.
History
Jessop Saville & Company was created in Sheffield in 1929 by combining J.J. Saville and Company with William Jessop and Company. Both predecessors had deep roots in the city’s specialist steel trade. William Jessop and Company developed from a partnership known as Mitchell, Raikes and Jessop, established in the late eighteenth century. Thomas Jessop and his brothers joined the enterprise in 1830, and the firm adopted the name William Jessop & Sons two years later. It expanded from its earlier works into the Brightside district and later operated a site at Kilnhurst. The Brightside works ultimately covered approximately 30 acres and became the principal industrial base associated with the Jessop name. Thomas Jessop became the company’s sole effective head after the deaths of his father and brothers. The business was converted into a limited company in 1875. Its development reflected the transition of Sheffield steelmaking from small-scale crucible production toward larger and more organized specialist manufacturing. The company also pursued overseas opportunities. Around 1901, high fuel costs in Sheffield and unfavorable United States tariff conditions made it difficult to compete in the American market. Jessop considered establishing melting capacity in the United States and was prepared to use the Jessop identity for steel produced there, rather than treating British origin as an essential condition of the brand. J.J. Saville and Company was based at the Libau Works and was associated with crucible steel and file manufacture. Its combination with William Jessop and Company created a substantial special-steel business with a strong local manufacturing identity. Jessop Saville’s activities later extended into research and advanced materials. Following the Second World War, Whiston Grange near Rotherham was first used for accommodation and training purposes before becoming a company research center in 1950. Laboratories there investigated Jessop alloys and other materials for aerospace applications, while also undertaking early work on casting titanium and titanium alloys. The postwar decades brought increasing pressure for consolidation within Sheffield’s steel industry. During the 1960s, Jessop Saville considered a plan with Samuel Osborn and Company, Edgar Allen and Company, and Hadfields Limited to combine foundry operations. The proposed entity would have been able to produce castings ranging from very small pieces to castings weighing as much as 40 tons. The negotiations did not result in the intended four-company merger. Instead, parts of the businesses were reorganized through separate transactions: Osborn and Hadfields combined their interests, while Edgar Allen acquired Jessop’s foundry-related operations. Jessop’s special-alloy medium-frequency melting and its three-ton electric furnace were moved to Edgar Allen facilities. The company’s titanium activities were also separated from the business. In the late 1960s, BSA, then the owner of Jessop Saville, sold its titanium interests to IMI. Jessop’s alloys were absorbed into IMI’s product range. This represented a significant transfer of technical capability after years of research into titanium and other advanced materials. The Brightside Lane works closed in the late 1980s and the site was subsequently cleared. After lying dormant, it was redeveloped as Jessop’s Riverside, an office and commercial district that retained the industrial name. In February 1998, Allegheny Teledyne acquired Special Melted Products Limited and Jessop Saville Limited. The transaction was motivated in part by the value of Jessop’s specialist products, particularly non-magnetic drill collars and downhole components used in oil and gas drilling. Publicly available reference material does not provide enough information to confirm the later legal status, ownership structure, or continuing use of Jessop Saville as a standalone brand.
