William Oughtred attended Eton School, and from there he went to King's College Cambridge, entering in 1592. Three years later he became a Fellow of King's College, received his B.A. in 1596 and his M.A. four years later. Oughtred was ordained an Episcopal minister in 1603. In 1604 he became vicar of Shalford and later, in 1610, he became rector of Albury. Oughtred was a private tutor to many, and allowed them to live in his house for free during their mathematical education. The most well known pupils of his are John Wallis, Christopher Wren and Richard Delamain. Also tutored the Earl of Arundel's son in the mid 1620's. He was described as being avidly interested in mathematics, and was known to lose several nights slepp while working on various projects. He was also an active alchemist. Accomplishments 1628 - Invention of an early form of the slide rule 1630 - Invented circular slide rule 1631 - first used x as symbol for multiplication, and :: for proportion. He experimented with many different notations for many things, but these caught on the best.

Background Picture The picture in the background is that of Albury Church, Surrey, taken by myself during August 2002. William Oughtred, the inventor of the slide rule, was rector there for 50 years from 1610 to his death in 1660. Herewith is a brief history of his life. Born: Eton, Buckinghamshire, 5 March 1575 Died: Albury, near Guildford, Surrey, 30 June 1660 William Oughtred attended Eton School, which although a very famous school was in fact his local school. From there he went to King's College Cambridge, entering in 1592. Three years later he became a Fellow of King's College, received his B.A. in 1596 and his M.A. in the year 1600. 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. Oughtred took private pupils who came to his house and lived there free of charge while they received mathematical instruction. He had many pupils but the most famous were John Wallis, Christopher Wren and Richard Delamain.

SURREY PEOPLE WILLIAM OUGHTRED 1574 - 1660 William Oughtred sleeps where he died, the last fifty years of his life was spent as the parson at Albury. He was born at Eton in 1574 and he went from the college there to Cambridge where it was discovered that he was a genius for mathematics. While an undergraduate there he wrote his Easy Method of Mathematical Dialling, which was translated into Latin by Sir Christopher Wren, who was at the time at Oxford. Oughtred was ordained in the the church in 1603 and came to Albury from Shalford in 1610 where he married and attended to his parish, and also spent time working away at his problem with an ink-horn fixed to his bed head and a tinderbox and candle by his side, ready to record a solution of his difficulties. Night after night would be spent working out a problem, and his most famous work embodied practically all that was known of algebra and arithmetic, and included Oughtred's invention, the X for multiplication, and the
