According to Vol. XLV. of the "Dictionary of National Biography," edited by Sidney Lee and published in 1896 by Smith, Elder & Co., 15 Waterloo Place, London: "Christopher Pinchbeck was born about 1670, possibly in Clerkenwell, London. He was a clockmaker and inventor of the copper and zinc alloy called after his name. He invented and made the famous astronomico-musical clock. In Appleby's _Weekly Journal_ of July 8th, 1721, it was announced that 'Christopher Pinchbeck, inventor and maker of the astronomico-musical clock, is removed, from St. George's Court (now Albion Place) to the sign of the "Astronomico-Musical Clock" in Fleet Street, near the Leg Tavern. He maketh and selleth watches of all sorts and clocks as well for the exact indication of the time only as astronomical, for showing the various motions and phenomena of planets and fixed stars.' Mention is also made of musical automata in imitation of singing birds and barrel organs for churches, as among Pinchbeck's manufactures. "Pinchbeck was in the habit of exhibiting collections of his automata at fairs, sometimes in conjunction with a juggler named Fawkes, and he entitled his stall 'The Temple of the Muses,' 'Grand Theatre of the Muses,' or 'Multum in Parvo.' The _Daily Journal_ of August 27th, 1729, announced that the Prince and Princess of Wales went to the Bartholomew Fair to see his exhibition, and there were brief advertisements in _The Daily Post_ of June 12th, 1729, and the _Daily Journal_ of August 22d and 23d, 1729. There is still a large broadside in the British Museum (1850 c. 10-17) headed 'Multum in Parvo,' relating to Pinchbeck's exhibition, with a blank left for place and date, evidently intended for use as a poster. He died November 18th, 1732; was buried November 21st, in St. Denison's Church, Fleet Street. "In a copy of the _Gentlemen's Magazine_, printed 1732, page 1083, there is an engraved portrait by I. Faber, after a painting by Isaac Wood, a reproduction of which appears in 'Britten's Clock and Watch Maker,' page 122. His will, dated November 10th, 1732, was proved in London on November 18th."
