JOHN See also:FLAMSTEED (1646-1719)  , See also:English astronomer, was See also:born at Denby, near See also:Derby, on the 19th of See also:August 1646 . The only son of See also:Stephen See also:Flamsteed, a maltster, he was educated at the See also:free school of Derby, but quitted it finally in May 1662, in consequence of a rheumatic See also:affection of the See also:joints, due to a chill caught while bathing . Medical aid having proved of no avail, he went to See also:Ireland in 1665 to be " stroked " by See also:Valentine Greatrakes, but " found not his disease to stir." Meanwhile, he solaced his enforced leisure with astronomical studies . Beginning with J . Sacrobosco's De sphaera, he read all the books on the subject that he could buy or See also:borrow; observed a partial See also:solar See also:eclipse on the 12th of See also:September 1662; and attempted the construction of measuring See also:instruments . A See also:tract on the See also:equation of See also:time, written by him in 1667, was published by Dr See also:John See also:Wallis with the See also:Posthumous See also:Works of J . See also:Horrocks (1673); and a See also:paper embodying his calculations of appulses to stars by the See also:moon, which appeared in the Philosophical Transactions (iv . 1099), signed In Mathesi a See also:sole fundes, an See also:anagram of " Johannes Flamsteedius," secured for him, from 167o, See also:general scientific recognition . On his return from a visit to See also:London in 167o he became acquainted with See also:Isaac See also:Newton at See also:Cambridge, entered his name at Jesus See also:college, and took, four years later, a degree of M.A. by letters-patent . An See also:essay composed by him in 1673 on the true and apparent diameters of the See also:planets furnished Newton with data for the third See also:book of the Principia, and he fitted numerical elements to J . Horrocks's theory of the moon . In 1674, and again in 1675, he was invited to London by See also:Sir See also:Jonas See also:Moore, See also:governor of the See also:Tower, who proposed to establish him in a private See also:observatory at See also:Chelsea, but the See also:plan was anticipated by the determination of See also:Charles II. to have the tables of the heavenly bodies corrected, and the places of the fixed stars rectified " for the use of his See also:seamen," and Flamsteed was appointed " astronomical observator " by a royal See also:warrant dated 4th of See also:March 1675 .

His See also:

salary of £See also:loo a See also:year was cut down by See also:taxation to 9o; he had to provide his own instruments, and to instruct, into the bargain, two boys from See also:Christ's See also:hospital . Sheer See also:necessity drove him, in addition, to take many private pupils; but having been ordained in 1675, he was presented by See also:Lord See also:North in 1684 to the living of Burstow in See also:Surrey; and his See also:financial position was further improved by a small See also:inheritance on his See also:father's See also:death in 1688 . He now ordered, at an expense of £120, a mural arc from See also:Abraham See also:Sharp, with which he began to observe systematically on the 12th of September 1689 (see See also:ASTRONOMY: See also:History) . The latter See also:part of Flamsteed's See also:life passed in a turmoil of controversy regarding the publication of his results . He struggled to withhold them until they could be presented in a See also:complete See also:form; but they were urgently needed for the progress of See also:science, and the astronomer-royal was a public servant . Sir Isaac Newton, who depended for the perfecting of his lunar theory upon " places of the moon " reluctantly doled out from See also:Greenwich, led the See also:movement for immediate communication; whence arose much See also:ill-feeling between him and Flamsteed . At last, in 1704, See also:Prince See also:George of See also:Denmark undertook the cost of See also:printing; a See also:committee of the Royal Society was appointed to arrange preliminaries, and Flamsteed, protesting and exasperated, had to submit . The See also:work was only partially through the See also:press when the prince died, on the 28th of See also:October 1708, and its completion devolved upon a See also:board of visitors to the observatory endowed with ample See also:powers by a royal See also:order of the 12th of See also:December 1712 . As the upshot, the Historia coelestis, embodying the first Greenwich See also:star-See also:catalogue, together with the mural arc observations made 1689-17o5, was issued under See also:Edmund See also:Halley's editorship in 1712 . Flamsteed denounced the See also:production as surreptitious; he committed to the flames three See also:hundred copies, of which he obtained See also:possession through the favour of Sir See also:Robert See also:Walpole; and, in See also:defiance of bodily infirmities, vigorously prosecuted his designs for the entire and adequate publication of the materials he continued to accumulate . They were but partially executed when he died on the 31st of December 1719 . The preparation of his monumental work, Historia coelestis Britannica (3 vols. See also:folio, 1725), was finished by his assistant, See also:Joseph Crosthwait, aided by Abraham Sharp .

The first two volumes included the whole of Flamsteed's observations at Derby and Greenwich; the third contained the See also:

British Catalogue of nearly 3000 stars . Numerous errors in this valuable See also:record having been detected by Sir See also:William See also:Herschel, See also:Caroline Herschel See also:drew up a See also:list of 56o stars observed, but not catalogued, while 111 of those catalogued proved to have never been observed (Phil . Trans. lxxxvii . 293; see also F . See also:Baily, See also:Memoirs See also:Roy . See also:Asir . Society, iv . 129) . The See also:appearance of the See also:Atlas coelestis, corresponding to the British Catalogue, was delayed until 1729 . A portrait of Flamsteed, painted by See also:Thomas See also:Gibson in 1712, hangs in the rooms of the Royal Society . The extent and quality of his performance were the more remark-able considering his severe See also:physical sufferings, his straitened means, and the antagonism to which he was exposed . Estimable in private life, he was highly susceptible in professional matters, and hence failed to keep on terms with his contemporaries .
