Richard Nichols, The Diaries of Robert Hooke, The Leonardo of London, 1635-1703 . Lewes, Sussex: The Book Guild, 1994, Pp. 185, £15.00. ISBN 0- 86332-930-6. Richard Nichols is a science master turned historian of science who celebrates in this book Robert Hooke’s contributions to the arts and sciences. The appreciation brings together comments from Hooke’s Diaries , and other works, on each of his main enterprises, and on his personal interaction with each of his principal friends and foes. Further references to Hooke and his activities are drawn from Birch’s History of the Royal Society, Aubrey’s Brief Lives , and the Diaries of Evelyn and of Pepys. The first section of the book, ‘Hooke the Man’, covers his early years of education at home in Freshwater, at Westminster school and at Christ Church, Oxford, where he soon joined the group of experimental philosophers who set him up as Curator of the Royal Society and Professor of Geometry at Gresham College, Bishopsgate. Hooke’s domestic life at Gresham College is described - his intimate relationships with a series of housekeepers, including his niece, Grace Hooke, and his social life at the College and in the London coffee houses.

Observ. XV. illustrated by Schem. IX. Figur:1 (figure 1 of this paper) in Robert Hooke's Micrographia (1665)1 is a description of Kettering–stone ‘which is brought from Kettering in Northampton–shire, and digg’d out of a Quarry, as I am inform'd’. As Curator of Experiments for the Royal Society from 1662, Hooke was charged by the Society to bring in at every meeting one microscopical observation at least. The minutes of the Society2 record that on 15 April 1663 ‘Mr Hooke showed the Company two Microscopicall Schemas; one representing the Pores of Cork … the other a Kettering Stone, appearing to be composed of Globules; and those hollow ones, each having 3 Coatings, sticking to one another, and so making up one entire firm stone’.


The period which saw the foundation of the Royal Society is rich in names remarkable for original achievement in the field of science, but, if we except Newton—and his first paper appeared eleven years after the foundation of the Society which is now being celebrated—none is more noteworthy than Robert Hooke. Without any advantages of birth or influence, poor in health and poor, as a young man, in worldly goods, he carried out work of the first importance in most branches of science then known, and of one branch, meteorology, he may claim to be the founder. Not only was he outstanding as an experimenter and as the inventor of new instruments, but he had an informed imagination which led him to astonishingly correct anticipations of many advances subsequently to be made. Although to many his name is known only through Hooke’s Law, outstanding figures in the history of science have been loud in his praises. Thomas Young wrote of the ‘inexhaustible but neglected mines of nascent inventions, the works of the great Robert Hooke’, a most apt phrase, since Hooke’s work contains so much that is suggestive and original, which his restless spirit lacked time to develop.

In 1675 Robert Hooke published, as one of his ‘Inventions’, a Latin anagram concerning the ‘true...form of all manner of arches for building’. His discovery was that the shape of a light flexible cord subjected to specified loads would, when inverted, give the required shape of the perfect (masonry) arch to carry those same loads. Hooke knew that the catenary curve was not given by the parabola y = ax 2 , but he was unable to solve the problem mathematically, and the decipherment of the anagram was not published until after his death. Four years earlier Hooke had stated to the Royal Society that the solution to the corresponding three–dimensional problem, that of the shape of the perfect dome, was the cubico–parabolical conoid; that is, the dome was formed by rotating the cubic parabola y = ax 3 about the y –axis. It is shown that the correct form of dome may be evaluated in terms of the integrals erf( t ) and erg( t ). Moreover, an alternative solution as a power series is rapidly convergent, and has a leading term in x 3 followed by a much smaller term in x 7 . Wren's design for the dome of St Paul's Cathedral made use of the idea of Hooke's ‘hanging chain’.

It is known that Robert Hooke was one of the Surveyors appointed after the Great Fire to assist the City in its urgent task of rebuilding, but until now only a very general understanding of the extent of his work and the time he spent on it has been gained. By examining contemporary manuscripts from the City of London's records it is now possible to make a reasonable estimate of the time he spent on the first major activities he was called upon to undertake amidst the ruins: the staking out of widened streets; and the staking out, measurement and certification of foundations of private buildings. Evidence that he staked out and certified nearly 3000 foundations between March 1667 when rebuilding began and 1672 when he started his diary is discussed and presented against a general background of the three organisations for which he worked: the Royal Society, Gresham College and the City.

Focuses on an important but overlooked building in late seventeenth-century London: the College of Physicians on Warwick Lane designed by the scientist and architect Robert Hooke in the 1670s. The building, which was commissioned in response to the previous college’s destruction in the Great Fire of London in 1666, was itself demolished in the nineteenth century. In this article, Matthew Walker argues that the conception and design of Hooke’s college had close links with the early Royal Society and its broader experimental philosophical program. This came about through the agency of Hooke—the society’s curator—as well as the prominence of the college’s physicians in the experimental philosophical group in its early years. By analyzing Hooke’s design for the college, and its prominent anatomy theater in particular, this article thus raises broader questions about architecture’s relationship with medicine and experimental science in early modern London.

Gentlemen,—I find it recorded that in the year 1662, which was the first year of the incorporation of the Royal Society of London, the celebrated mathematician, Robert Hooke, drew up “Proposals for the good of the Royal Society,” the third article of which was as follows :— “That every member of the Society shall be equally obliged to promote the ends thereof by paying 52s. yearly, and by doing some one duty that shall be charged on him by the Council once a year, or, if his occasions will not permit, to pay 52s. more per annum.’ This proposed salutary rule does not seem ever to have been enacted by the Royal Society of London, nor do I believe that any analogous article forms part of the statutes of this Society, and yet it is in accordance with the spirit of such a rule that I appear before you this evening.


ONE would be hard pressed to name a device superior to the mariner’s sextant by which physical principles are better adapted to solve a relatively simple practical problem. The sextant, an instrument superbly elegant in its simplicity, designed merely to measure accurately the altitude of a heavenly body from a platform as unstable as the heaving deck of a ship at sea, is ideal for its purpose. The first part of this paper describes the principal altitude measuring devices employed during the Golden Age of Discoveries. It covers a period of about a quarter of a millennium from the time when Portuguese mariners under the sponsorship of Prince Henry the Navigator (1394-1460) first struck out to navigate the open Atlantic, to the time when Robert Hooke (1635-1703), the eminent experimental philosopher of the seventeenth century, first described, in 1666, a reflecting instrument for measuring altitudes at sea.
