Footnotes: John Ellicott was born in 1706, the son of a clockmaker of the same name. He was one of the outstanding clockmakers of the 18th century, producing a large number of high quality clocks for the home market and export, his work was particularly valued by the Spanish Royal family. He developed his own form of temperature compensated pendulum and was instrumental in the perfection of the cylinder escapement. He was clockmaker to King George III, a position which paid £150 per annum. He was elected a fellow of the Royal Society on the 26th of October 1738 and published articles on clocks and an equation of time table in the Philosophical Transactions for the Society. He supplied portable regulators to astronomers notably; Nevil Maskelyne, Charles Mason and James Cook for the recording of the transit of Venus. Ellicott was a keen astronomer and observed the transit of Venus in 1761 from an observatory built in his home in Hackney. He worked from St Swithins Alley, Royal Exchange, London. He was thus capable of making the highest grade precision timekeepers, the most elaborate 'fancy' clocks with finely cast and chased silver mounts, but also the beautifully proportioned and eminently usable fare such as the current clock.
