WILLIAM OUGHTRED OUGHTRED, WILLIAM (fl. 1575-1660), English mathematician, was born at Eton, and educated there and at King's College, Cambridge, of which he became fellow. Being admitted to holy orders, he left the university about 1603, and was presented to the rectory of Aldbury, near Guildford in Surrey; and about 1628 he was appointed by the earl of Arundel to instruct his son in mathematics. He corresponded with some of the most eminent scholars of his time on mathematical subjects; and his house was generally full of pupils from all quarters. It is said that he expired in a sudden transport of joy upon hearing the news of the vote at Westminster for the restoration of Charles II. He published, among other mathematical works, Clavis Mathe-matica, in 1631, in which he introduced new signs for certain mathematical operations (see ALGEBRA) ; a treatise on navigation entitled Circles of Proportion, in 1632; works on trigonometry and dialling, and his Opuscula Mathematica, published posthumously in 1676.

A contemporary of Oughtred's, Edmund Gunter, devised a logarithmic rule in 1620, which could be used to multiply and divide using a pair of calipers. Oughtred was the first to see that a simpler and more sophisticated method of multiplication and division could be achieved by placing two logarithmic rules side by side and using the position of the numbers relative to each other to calculate the desired results. Oughtred's most important work, Clavis Mathematicae (1631), included a description of Hindu-Arabic notation and decimal fractions and a considerable section on algebra. He experimented with many new symbols including for multiplication and :: for proportion. Like all Oughtred's works it was very condensed containing only 88 pages. He also developed the circular slide rule, which operated in the same fashion as a linear slide rule, except that it makes use of an inner and an outer ring Oughtred published his renowned work Circles of Proportion and the Horizontal Instrument in 1632.

The invention of the Slide Rule Edmund Gunter (15811626) Edmund Gunter's most important book entitled Description and use of the Sector , was first published in English in 1623. This has been described as ``the most important work on the science of navigation to be published in the seventeenth century." A sector is a mathematical instrument consisting of two hinged arms on which there are engraved scales which can be used to help with calculations. This is not a slide-rule; the single scale is used in conjunction with a pair of compasses. What makes Gunter's sector special is that it is the first mathematical instrument to be inscribed with a logarithmic scale to help solve numerical problems. In practice the points of the compass tend to damage the scales which reduces the accuracy of the instrument. William Oughtred (15741660) William Oughtred was a clergyman and keen mathematician. He is believed to have introduced the x symbol for multiplication in his book Clavis Mathematicae (Key to Mathematics), written about 1628 and published in London in 1631. This was a very important maths text book at the time. Newton read and was influenced by it for example. He is now generally though to be the inventer of the slide rule. Both straight and circular rules are described in a book with the title
