Thomas Key was an important woodwind and brass maker in London from about 1800. In 1808, he was appointed Musical Instrument Maker to the Prince of Wales and the Dukes of York, Kent, Cumberland and Cambridge. He produced a wide range of instruments including flutes, bassoons and serpentcleides. He was succeeded by his son Frederick, in 1854 and in 1857 the business merged with Rudall becoming Key, Rudall and Co but a year later the name of Key was dropped. Interesting that when Rudall took over their business with was to take over the military brass and percussion and include it as part of their catalogue.
