The Oughtred Society dedicated to the history and collection of slide rules William Oughtred - The Inventor of the Slide Rule William Oughtred was one of the world's great mathematicians. He attended Eton School and King's College, receiving his M.A. in 1600. In 1603 he was ordained as an Episcopal minister. In the 17th century, becoming a clergyman was a common and well respected career option for a well educated man. Like many others of his day, Oughtred was likely not a formally trained mathematician, rather he was largely self-taught. He reputedly had a burning curiosity for mathematics and along with Harriot, he devised a standardized notation for algebra, some of which remains in use today. Oughtred's passion for mathematics was so great that he maintained a free school for young men interested in the science. 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. 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.

It is surprising that although very little mathematics was taught at either Eton or Cambridge at this time Oughtred became passionately interested. He wrote:- ... the time which over and above those usuall studies I employed upon the mathematicall sciences I redeemed night by night from my naturall sleep, defrauding my body, and inuring it to watching, cold, and labour, while most others tooke their rest. Oughtred was ordained an Episcopal minister in 1603. In 1604 he became vicar of Shalford and later, in 1610, he became rector of Albury.

document.write(""); OUGHTRED, WILLIAM 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. OUIDA, the pen name—derived from a childish attempt to pronounce " Louisa "—of Maria Louise [de la] Ramee (1839-1908), English novelist, born at Bury St Edmunds, where her birth was registered on the 7th of January 1839. Her father, Louis Ramee, was French, and her mother, Susan Sutton, English. At an early age she went to live in London, and there began to contribute to the New Monthly and Bentley's Magazine. In 1860 her first story, afterwards republished as Held in Bondage (1863), appeared in the New Monthly under the title of Granville de Vigne, and this was followed in quick succession by Strath-more

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.
