Hooke, Robert
, an eminent English mathematician, and one of the most inventive geniuses that the world has ever seen, was son of Mr. John Hooke, rector of Freshwater in the Isle of Wight, and born there July 18, 1635. He was designed for the church; but being of a weakly constitution, and very subject to the head-ache, he was left to follow the bent of his genius, which led him to mechanics, and first appeared in his making little toys, which he did with wonderful art and dexterity. Seeing, on one occasion, an old brass clock taken to pieces, he made a wooden one that would go: he made likewise a small ship about a yard long, fitly shaped, masted, and rigged, with a contrivance to make it fire small guns, as it was sailing across a haven of some breadth. These indications led his friends to think of some trade for him in which such talents might be useful; and after his father’s death in 1648, as he had also a turn for drawing, he was placed with sir Peter Lely, but the smell of the oil-colours increased his headaches, and he quitted painting in a very short time.*
Aubrey says he had some instructions in drawing from the celebrated Sam. Cooper, but does not know whether this was before or after he went to Lely. He gives us an apecdote of Hooke, however, which is very characteristic of that sordid regard for money which predominated all his life. His father left him 100l. which was to have been paid as au apprentice fee to Lely; but after he had been some time upon trial, Hooke left him, as thinking he could do all that was to be done, and keep his hundred pounds. When he went to Busby’s he “lodged his 100l. with him.” Letters by Eminent Persons, 1813, 3 vois. 8vo.
In 1668, Hevelius, the famous astronomer at Dantzick, presented a copy of his “Cometographia” to Hooke, in acknowledgment for an handsome compliment which Hooke had paid to him on account of his “Selenographia,” printed in 1647; and Hooke, in return, sent Hevelius a description of the dioptric telescope, with an account of his manner of using 1 it, and recommended it to him as preferable to those with plain sights. This circumstance gave rise to a great dispute betwee’n them, noticed in our account of Hevelius, hi which many learned men afterwards engaged, and which Hooke so managed, as to be univeraiiy condemned, though it has since been agreed that he had the best side of the question. In 1671 he attacked sir Isaac Newton’s “New Theory of Light and Colours;” where, though he was forced to submit in respect to the argument, he is said to have couie off with a better reputation than in the former instance. The Royal | Society having begun their meetings at Gresham-college, in Nov. 1674, the committee in December allowed him 40l. to erect a turret over part of his lodgings, for proving his instruments, and making astronomical observations; and the year following he published “A Description of Telescopes, and some other instruments,” made by him, with a postscript, complaining of some injustice done him by Oldenburg, the publisher of the “Philosophical Transactions,” in regard to his invention of pendulum watches. This charge drew him into a dispute with that gentleman, which ended in a declaration of the Royal Society in their secretary’s favour. Oldenburg dying in Aug. 1677, Hooke was appointed to supply his place, and began to take minutes at the meeting in October, and published seven numbers of the “Philosophical Collections,” which have been always considered as a part of the “Philosophical Transactions.” Soon after this be grew more reserved than formerly, and though he read his Cutlerian lectures, and often made experiments, and shewed new inventions before the Royal Society, yet’he seldom left any account of them to be entered in their registers, designing, as he said, to fit them for himself, and make them public, which however he never performed. In 1636, when sir Isaac Newton’s Principia were published, Hooke, with that jealousy which was natural to him, claimed priority respecting the idea of gravitation. Newton, with a candour equally natural to him, admitted his claim, but shewed at the same time that Hooke’s notion of gravitation was different from his own, and that it did not coincide with the phenomena. In reality, the notion of gravitation is as ancient at least as the days of Lucretius, and is particularly notice<i by Kepler. Newton’s merit consisted, not in ascribing the planetary motions to gravitation, but in determining the law which gravitation follow:;, and in shewing that it exactly accounts for all the planetary phenomena, which no other system. does.
In 1687, his brother’s daughter, Mrs. Grace Hooke, who had lived with him several years, died; and he was so affected at her death, that he hardly ever recovered it, but was observed from that time to grow less active, more melancholy, and, if possible, more cynical than ever. At the same time a chancery-suit, in which he was concerned with sir John Cutler, on account of his salary for reading the Cutlerian lectures, made him very uneasy, and | increased his disorder. In 1691, he was employed in forming the plan of the hospital near Hoxton, (bun Jed by Aske, alderman of London, who appointed archbishop Tillotson one of his executors; and in December the same year, Hooke was created M. D. by a warrant from that prelate. He is also said to have been the architect of Bedlam, and the College of Physicians. In July 1696, his chancerysuit for sir John Cutler’s salary was determined in his favour, to his inexpressible satisfaction. His joy on that occasion was found in his diary thus expressed “Domshlgissa that is, Deo Optimo Maximo sit honor, laus, gloria, in saecula saeculorum. Amen. I was born on this day of July, 1635, and God has given me a new birth: may I never forget his mercies to me! whilst he gives me breath may I praise him!” The same year an order was granted to him for repeating most of his experiments, at the expence of the Royal Society, upon a promise of his finishing the accounts, observations, and deductions from them, and of perfecting the description of all the instruments contrived by him, which his increasing illness and general decay rendered him unable to perform. For the two or three last years of his life he is said to have sat night and day at a table, engrossed with his inventions and studies, and never to have gone to bed, or even undressed; and in this wasting condition, and quite emaciated, he died March 3, 1702, at his lodgings in Gresham-college, and was buried in St. Helen’s church, Bishopsgate- street, his corpse being attended by all the members of the Royal Society then in London.
Waller, the writer of his life, has given the following character of him, which, though not an amiable one, seems to be drawn with candour and impartiality. He was in person but a despicable figure; short of stature, very crooked, pale, lean, and of a meagre aspect, with dark brown hair, very long, and hanging over his face, uncut, and lank. Suitable to this person, his temper was penurious, melancholy, mistrustful, and jealous; which qualities increased upon him with his years. He set out in his youth with a collegiate or rather a monastic recluseness, and afterwards led the life of a cynical hermit; scarcely allowing himself necessaries, notwithstanding the great increase of his fortunes after the fire in London .*
Sir Godfrey Copley, in a letter written about the time of Hooke’s death, says, " Mr. Hooke is very crazy much concerned for fear he should outlive his
|estate. He hath starved one old woman already; and I believe he will endanger himself to save sixpence for any thing he wants.“In another, written a few weeks after his death, Sir Godfrey says, ”I wonder old Dr. Hooke did not choose rather to leave his 1-2.000l. to continue what he had promoted and studied all the days of his life, I mean mathematical experiments, than to have it go to those whom he never saw or cared for. It is rare that virtuosos die rich, and it is pity they should if they were like him." Dr. Ducarel’s Mss. in Mr. Nichols’s possession.
His papers being put by his friends into the hands of Richard Waller, esq. secretary to the Royal Society, that gentleman collected such as he thought worthy of the press, and published them under the tide of his “Posthumous Works,” in 1705, to which he prefixed an account of his life, in folio.- It is thought, that this gentleman would have published more of Hooke’s manuscripts, had he lived. Mr. Professor Robison of Edinburgh, who ascribes the invention of spring watches to Hooke, had an opportunity of seeing some of Hooke’s Mss. that had been rescued from the fire at the burning of Gresham-college, and says that they are full of systematic views many of them, it must be acknowledged, hasty, inaccurate, and | futile, but still systematical. Hooke called them algebras, and considered thein as having a sort of inventive power, or rather as means of discovering things unknown by a process somewhat similar to that art He valued himself highly on account of this view of science, which he thought peculiar to himself: and he frequently speaks of others, even the most eminent, as childishly contenting themselves with partial views of the corners of things. He was likewise very apt to consider other inventors as encroacbers on his systems, which he held as a kind of property, being seriously determined to prosecute them all in their turn, and never recollecting that any new object immediately called him off, and engaged him for a while in the most eager pursuit. His algebras had given him many signal helps, and he had no doubt of carrying them through in every investigation. Stimulated by this overfond expectation, when a discovery was mentioned to him he was too apt to think and to say, that he had long ago invented the same thing, when the truth probably was, that the course of his systematic thoughts on the subjects with which it was connected had really suggested it to him, with such vivacity, or with such notions of its importance, as to make him set it down in his register in its own systematic place, which was his constant practice: but it was put out of his mind by some new object of pursuit. These remarks are part of a series, by the same learned professor, on the merits and inventions of Dr. Hooke, which are new, and highly necessary to enable the reader to form a just estimate of Hooke as a benefactor to science. They are to be found in the “Encyclopaedia Britannica,” under the article Watch, and in Dr. Gleig’s supplement to that work, under Hooke. No English biographer appears to have done so much justice to our philosopher. 1 >1
