Reference II: Mercer, Tony, 'Chronometer Makers of the World', Colchester, Essex: N.A.G. Press Ltd., 1991, pp. 128,129. Edward John Dent was born in 1790 and died in 1853. Probably the greatest accomplishment of his career was receiving the commission from the Board of Longitude to build a great clock of the Houses of Parliament fondly referred to as 'BIG BEN' and probably the most famous clock in the world. Dent was in partnership with John Roger Arnold from 1830 to 1840 and set-up on his own in 1840 at 64 Strand. In 1828, Dent's chronometer No.114 won first prize at the Premium Trials with a variation of 1/2 second in 12 months for which the admiralty awarded a price of L300. Dent's chronometers were used on many explorations in Polar regions and in the Tropics. Number 1800 was owned by David Livingston during his African travels. The Royal Warrant was granted in 1841 as 'Chronometer Maker to the Queen and HRH Prince Albert'. Dent was an eleoquent man continually writing to horological and scientific journals and he took out many patents. Dent trained many of the later great chronometer makers such as Kullberg, Johannsen, and Mercer.
