Eardley Norton, who worked at 45 St. John Street, Clerkenwell, London, is particularly famous for his musical and astronomical clocks. First recorded in 1762 he was registered in the Clockmakers' Company from 1770-1794. A tortoiseshell-veneered and ormolu musical clock by this maker is in the Metropolitan Museum of Art, New York. Its twin is illustrated in A. W.J.G. Ord-Hume, The Musical Clock, Derbyshire, 1995, p. 75, pl. IV/25-27. A superb four-dial astronomical clock by him is in the British Royal Collection (see C. Jagger, Royal Clocks, Hale, 1983, figs.151-152). Britten records him also as having made a fine musical clock for Empress Catherine of Russia (Old Clocks and Watches and Their Makers, Spon, Seventh Edition, 1956, p.446).
