Jessop Saville and Company, the Sheffield-based special steel makers, was founded in 1929 following a merger of J.J.Saville and Co., Limited and William Jessop and Company, both of these being long established in the trade and in the city.
Thomas Jessop was born on 30 January 1804 at the family home in Blast Lane, Sheffield. The house was situated next to William Jessop’s works, the company, taking the name of the partners, being known as Mitchell, Raikes and Jessop. With expanding markets in the United States, Thomas and his brothers joined the business in 1830 and just two years later the small crucible steelmakers became William Jessop & Sons.
The business moved to a site in the Brightside area of Sheffield and later a works at Kilnhurst was added. The Brightside works eventually covered 30 acres (120,000 m2) and included the site of the former water works. Following the deaths of his father and brothers, Thomas was in sole charge of the business by 1871. The company which was originally established in 1793 became a Limited Company in 1875. Thomas Jessop died on 30 November 1887 and is buried in Ecclesall Parish Churchyard.
Jessops in America. In 1901, with problems in Sheffield caused by the high price of fuel and an adverse American tariff the company was having difficulty offering competitive prices to its U.S. customers. Following an amalgamation of some U.S. crucible steel makers, which would make competition even harder, it was considered that a successful melting facility could be set up in the U.S.A. Many British steel-makers considered that the "Made in England" or "Made in Sheffield" marks were a big selling point for their materials, however Jessop's did not hold the view and considered that they could use their Sheffield name on steel which was made in America.
J.J.Saville were Sheffield crucible steel and file makers based at Libau Works in the city.
It was seen in the mid-1960s that some rationalisation was needed within the Sheffield steel industry, particularly steel founding. With respect to this Jessop Saville separated its interests. Similar moves were taking place at Samuel Osborn & Company, Edgar Allen and Company and Hadfields Limited.
The intention was to merge the foundry interests of the four companies to form one large steel foundry with the capability of making castings from a few ounces to 40 tons, with only English Steel Corporation's Grimesthorpe foundry in the city able to make larger. As negotiations were taking place the deal fell through leaving Osbourne's and Hadfield's to merge, with the foundry being located on Hadfield's East Hecla (Vulcan Road) site, and Edgar Allen's to purchase Jessop's, relocating Jessop's special alloy (medium frequency) melting on Edgar's Sheffield Road site and the 3-ton electric furnace at their Imperial Steel Works site.
