HOOKE, See also:ROBERT (1635–1703) , See also:English experimental philosopher, was See also:born on the 18th of See also:July 1635 at See also:Freshwater, in the Isle of See also:Wight, where his See also:father, See also:John Hooke, was See also:minister of the See also:parish. After working for a See also:short See also:time with See also:Sir See also:Peter See also:Lely, he went to See also:Westminster school; and in 1653 he entered See also:Christ See also:Church, See also:Oxford, as servitor. After 1655 he was employed and patronized by the Hon. Robert See also:Boyle, who turned his skill to See also:account in the construction of his See also:air-See also:pump. On the 12th of See also:November 1662 he was appointed See also:curator of experiments to the Royal Society, of which he was elected a See also:fellow in 1663, and filled the See also:office during the See also:remainder of his See also:life. In 1664 Sir John See also:Cutler instituted for his benefit a See also:mechanical lectureship of £5o a See also:year, and in the following year he was nominated See also:professor of See also:geometry in See also:Gresham See also:College, where he subsequently resided. After the See also:Great See also:Fire of 1666 he constructed a See also:model for the rebuilding of the See also:city, which was highly approved, although the See also:design of Sir C. See also:Wren was preferred. During the progress of the See also:works, however, he acted as surveyor, and accumulated in that lucrative employment a sum of several thousand pounds, discovered after his See also:death in an old See also:iron See also:chest, which had evidently lain unopened for above See also:thirty years. He fulfilled the duties of secretary to the Royal Society during five years after the death of See also:Henry See also:Oldenburg in 1677, See also:publishing in 1681–1682 the papers read before that See also:body under the See also:title of Philosophical Collections. A protracted controversy with Johann See also:Hevelius, in which Hooke urged the advantages of telescopic over See also:plain See also:sights, brought him little but discredit. His reasons were See also:good; but his offensive See also:style of See also:argument rendered them unpalatable and himself unpopular.

Many circumstances concurred to embitter the latter years of his life. The death, in 1687, of his niece, Mrs See also:

Grace Hooke, who had lived with him for many years, caused him deep affliction; a See also:law-suit with Sir John Cutler about his See also:salary (decided, however, in his favour in 1696) occasioned him prolonged anxiety; and the repeated anticipation of his discoveries inspired him with a morbid See also:jealousy. Marks of public respect were not indeed wanting to him. A degree of M.D. was conferred on him at Doctors' See also:Commons in 1691, and the Royal Society made him, in 1696, a See also:grant to enable him to See also:complete his philosophical inventions. While engaged on this task he died, worn out with disease, on the 3rd of See also:March 1703 in See also:London, and was buried in St See also:Helen's Church, Bislropsgate See also:Street. In See also:personal See also:appearance Hooke made but a sorry show. His figure was crooked, his limbs shrunken; his See also:hair hung in dishevelled locks over his See also:haggard countenance. His See also:temper was irritable, his habits penurious and solitary. He was, however, 'blameless in morals and reverent in See also:religion. His scientific achievements would probably have been more striking if they had been less varied. He originated much, but perfected little. His See also:optical investigations led him to adopt in an imperfect See also:form the undulatory theory of See also:light, to anticipate the See also:doctrine of interference, and to observe, independently of though subsequently to F.

M. See also:

Grimaldi (1618–1663), the phenomenon of diffraction. He was the first to See also:state clearly that the motions of the heavenly bodies must be regarded See also:asa mechanical problem, and he approached in a remarkable manner the See also:discovery of universal See also:gravitation. He invented the See also:wheel See also:barometer, discussed the application of barometrical indications to meteorological forecasting, suggested a See also:system of optical telegraphy, anticipated E.F.F. Chladni's experiment of strewing a vibrating See also:bell with See also:flour, investigated the nature of See also:sound and the See also:function of the air in respiration and See also:combustion, and originated the See also:idea of using the pendulum as a measure of gravity. He is credited with the invention of the See also:anchor escapement for clocks, and also with the application of See also:spiral springs to the balances of watches, together with the explanation of their See also:action by the principle Ut lensio sic vis (1676). His See also:principal writings are Micrographia (1664); Lectiones Cutlerianae (16i4–16i9); and See also:Posthumous Works, containing a See also:sketch of his Philosophical See also:Algebra," published by R. See also:Waller in 1705.
