In 1891 the business was established by Clift Alexander Mawer Clark, operating from 138 Fenchurch Street, London. In the late 1890s the firm’s name went from Alexander Clark, to operating under the name The Alexander Clark Manufacturing Co. With the growth of business further manufacturing premises were opened at 29 Market Place, Oxford Street in 1894 when he was joined by Robert Frederick Mosley (the son of R.F. Mosley). In 1901 Robert Frederick lived at the Clark’s Market Place workshop and the Mosleys became partners in the Clark company.
From 1900 the firm could be seen as active from Welbeck Works, Randall Street, Sheffield and then later transferring to James Street Works, St. Paul's, Birmingham, in 1918. In addition to these further locations the London activity moved to accommodate the growing business including: 29 Market Place, London (1894-1910), 188 Oxford Street, London (1900-1915), 125-126 Fernchurch Street, London (1909-1918), 38-40 Mitre Street, Aldgate, London (1921), 17 Sycamore Street, Sheffield (1921) and 38 Leadenhall Street, London (1941).
In 1912 the first was converted into a limited liability company and operated under the name The Alexander Clark Co Ltd. It was at this time the firm advertised reproduction silver historical pieces, including items from the Tudor period, Mediaeval beakers and antique jugs from the designs of those found at Pompeii.
In 1914 the company had over 600 employees acting as silversmiths, cutlers and even specialising in mounting precious stone. They specialised in the production of silver, electroplate, cutlery and high-quality leather goods. They also produced their own brand of silverplate called ‘Welbeck Silver Plate’, and they marked these pieces with ‘Welbeck’.
By 1918 the company started manufacturing in Birmingham, after the First World War and later went on to produce stainless steel flatware, continuing with the firm’s name until the 1940s.
