Mappin & Webb traces its origins to 1775, when Jonathan Mappin opened a silver workshop in Sheffield, then as now a major centre of the English silver trade. The business eventually became Mappin Brothers.
One of Jonathan Mappin’s great grandsons, John Mappin, started his own business in London, Mappin & Company, in 1860, which became Mappin, Webb & Co. in 1862 after John Mappin was joined by his brother-in-law George Webb. The first Mappin & Webb store opened in 1860 at 77-78 Oxford Street, London and the company’s candelabras, fine silverware and vanity products swiftly gained renown. As a natural progression from silverware, Mappin & Webb began designing jewellery. Mappin, Webb & Co. acquired Mappin Brothers in 1903. Reference: Wikipedia
