A manufacturer of silver and silver-plated wares, Henry Dawson Wilkinson & Co was established in 1833 in Sycamore Street (when a silver mark was registered).   Its proprietor, Henry D. Wilkinson, was born in Portsmouth in about 1811 and may have been the son of Henry Wilkinson of Low Street.  By 1837, Henry D. Wilkinson’s business was operating from Shrewsbury Works in Broad Street.  The firm opened an outlet at Bell’s Buildings, Salisbury Square, London (by 1845 the London address was Thanet Place).  Wilkinson was declared bankrupt in October 1848.  In December 1848, he became one of the first Sheffield firms to take out a licence for electro-plate manufacture from Elkington of Birmingham.  However, by 1849 Wilkinson had vacated Shrewsbury Works to Roberts & Hall (forerunners of Martin, Hall) and moved to Union Lane, where he was listed as an electro-plater and gilder.  In 1851, he employed sixteen men.  The following year, he advertised in a Sheffield directory as a manufacturer of over twenty years.  Wilkinson lived at Clarendon Villa on Ecclesall Road.  He died, aged 58, on 18 June 1859 ‘after a long illness’.  He was buried in an unconsecrated grave in the General Cemetery.   The firm had been in financial difficulties again and the Union Lane premises were taken over by silver-plate manufacturer Charles Anderton.
