Administrative / biographical background:
Berkshire trade directories show Leonard Wilder established as an ironfounder and plough manufacturer at Mill bridge, Wallingford, by 1830. By 1847 he had been succeeded by Richard Wilder, ironfounder, in Fish Street, Wallingford, remaining under that name until 1868. In 1869 the firm is listed as Wilder Brothers. By 1876 considerable expansion had produced R.J. and H. Wilder [the partners being Richard, James and Henry Wilder] engineers, iron and brass founders, millwrights, and manufacturers of agricultural implements and machines, at Wallingford iron works. By 1883 they also had an office in St Mary's Street. In the 1890s expansion resulted in a firm which was described in 1895 as being "engineers, ironfounders, implement manufacturers, & steam plough & threshing machine proprietors. They had also become coke, coal and salt merchants, based at the St Mary's Street Office. Between 1903 and 1911 they dropped this last branch, and began to manufacture various types of wagon and carts, and in 1909 began as motor engineers. Between 1928 and 1931 the firm resumed activity as a coal merchant. Between 1935 and 1939 the firm was renamed John Wilder Ltd, and had also become electrical engineers, having merged with John Wilder of Reading.
(This firm is first recorded in 1869 as James Wilder & Sons, at the Yield Hall Foundry in Minster Street, although in the early 1930s it moved to The Cattle Market.)
