The firm Hunt & Roskell dates back to the early 19th century, when Paul Storr established his firm Storr & Co. in 1819. Within a few years he partnered first with John Mortimer, followed soon after by John Samuel Hunt. When Storr retired in 1838, the firm was renamed Mortimer & Hunt. Upon Mortimer’s retirement in 1843, the firm became Hunt & Roskell. At this time the firm comprised John Samuel Hunt and his son John Hunt, Robert Roskell Jn. (son of the Liverpool watchmaker Robert Roskell), and Charles Frederick Hancock. The firm increasingly gained recognition over the years, making jewelry for Queen Victoria and exhibiting in the 1851 London Great Exhibition and many others, including New York in 1851 and Paris in 1867.
