The story
James Foster was the half-brother of John Bradley who founded the company John Bradley & Co, taking a lease on land near the canal at Stourbridge in 1800 with the aim of developing an ironworks. The deed of partnership for the company was drawn up in 1802 which granted a share in the company to Bradley's six half-brothers and sisters. By 1813 only John Bradley and James Foster had shares in the company and on Bradley's death in 1816, James Foster took control of the enterprise, which included the Stourbridge Iron Works.
John Urpeth Rastrick was an engineer born in 1780 at Morpeth in Northumberland. After finishing an apprenticeship with his father, which included work on steam engines, he worked first at the Ketley Ironworks and subsequently worked in partnership with John Hazledine of Bridgnorth. In 1808 he constructed a locomotive for Richard Trevithick and subsequently constructed a bridge at Chepstow (opened 1816). Shortly afterwards (1817) Rastrick left the partnership with Hazledine's company and moved to West Bromwich.
In June 1819 Rastrick and James Foster agreed to form the firm Foster, Rastrick & Company at a site next to the Stourbridge Iron Works. A new foundry was constructed from 1820-1821 to produce products for the partnership.
