- There is an Aristotle Lane in the northwest of Oxford, leading to a trading estate and to Port Meadow.
- Elias Ashmole (1617-1692) spent 1645-1646 at Oxford and became a member of Brasenose College and studied natural philosophy, mathematics, astronomy and astrology. He was a founder member of the Royal Society. He later obtained the Tradescants' collections and gave them to found the Ashmolean Museum in 1683.
- Michael Atiyah was Reader (1961-1963), then Savilian Professor of Geometry (1963-1969), then Royal Society Research Professor and Fellow of St Catherine's in 1972-1990.
- Roger Bacon (1214-1294 (or 1292)) studied at Oxford, pursuing Greek at the suggestion of Grosseteste. After some time at Paris, he returned to Oxford in 1250-c1267, but retired from an active part in university life in 1257. After a period in Paris, apparently including 14 years in confinement, he returned to Oxford in 1292 and died there. He is said to have built an astronomical tower on the bridge over the Thames (= Isis). This became known as the Folly or Friar Bacon's Study and the bridge is still called Folly Bridge even though the tower was torn down in 1779. The present tower dates from 1849.  .  gives a drawing of the tower in the 18th century.  is a picture of an eighteenth-century painting in the Museum of the History of Science showing the tower.  and other sources relate that tradition says Bacon used the story over the gateway of the bridge and that a Mr Welcome later leased it and added a story, which became known as Welcome's Folly, hence the name of the bridge. Bacon is said to have made astronomical studies from the church tower in Sunningdale, some miles south of Oxford. There is a model of the thirteenth century church showing Bacon on the tower with an astrolabe. Bacon gives a reasonably clear description of the telescope and microscope, but there is no physical evidence for these and the description doesn't clearly indicate that he had made these. He gives a recipe for a rather feeble gunpowder, certainly not original with him, but he did suggest enclosing it to increase the effect. He anticipating circumnavigating the globe and suggested calendar reform. He lived in the Franciscan House in Oxford, now built over by the Westgate Centre and its car park in Paradise Street, in 1250? - 1257?. There is a plaque high up, behind some trees, on the south wall of the Westgate Centre, just to the east of the facing carpark ; thanks to Eddie Mizzi for a photo;  seems a bit dubious about the site. He is thought to have died in Oxford and to be buried in the Franciscan burial ground of Grey Friars church. ;  He is sometimes said to have been at Merton or Brasenose, but neither college was in existence at the time. A statue of Bacon, holding an armillary sphere, was added to the statues in the court of the University Museum in 1914.

- Robert Boyle (1627-1691) settled in Oxford in 1654. Then or a bit later, he took lodgings with a leading apothecary, John Cross, at his house Deep Hall in the High Street. He stayed there until 1668, carrying out his experiments, using Cross's laboratory. He and Peter Sthael lectured on Chemistry at the Ram Inn, 113 High Street - John Locke attended . The 1654 air pump experiments of Boyle and Hooke are commemorated by a plaque on University College, where the Shelley Memorial is on the site of the house or laboratory. Other sources say the laboratory site is now part of the Fellows' Garden. Boyle's The Sceptical Chymist, 1661, is considered the beginning of chemistry - in this he elucidates the idea of an element and defines acid and alkali. In 1661, he discovered that heating wood gave off condensable vapours and found a liquid similar to alcohol, but not the same, which was called 'wood alcohol'. Boyle and Hooke discovered Boyle's law, c1654, but it was not published until 1662 in the second edition of On the Spring and Weight of Air. The air-pump is commemorated in a southern constellation - Machina Pneumatica or Air Pump . ( reports that constellations of Telescopium, Microscopium, Sextans and Horologium also exist.) In 1663, he described the colours of soap bubbles. Many of the meetings of the Oxford precursor of the Royal Society were held at Boyle's rooms. Boyle moved to London in 1668.

He succeeded Keill as Savilian Professor of Astronomy (1721-1764). He discovered the aberration of light in 1725 and verified the nutation of the earth's axis in 1748. At first, he only came to Oxford to give his Savilian lectures, but in 1732 he moved to Stable Hall, 7 New College Lane. He regularly lectured on experimental philosophy from 1729 until 1760. After his appointment as Astronomer Royal in 1742, he moved to London and spent little time in Oxford though he was the first Reader in Experimental Philosophy from 1749 . DD in 1742. Portrait in the Bodleian.
- Thomas Bradwardine (c1290-1349) was a fellow of Balliol, then the leading figure of a group of scientists at Merton College and wrote several books on mathematics before becoming Archbishop of Canterbury. He is described as the first to treat theology on mathematical principles and he also wrote on the quadrature of the circle. Chaucer refers to him in his Nun Priest's Tale. The group's main work consisted of computation of improved astronomical tables. ;

He was first President of the Royal Society.   refers to a monument to him in Christchurch Cathedral, but this is to his father, also William, and mother .
- Giordano Bruno (1548-1600) spent 1583-1585 in England and spent some time at Oxford, visiting John Florio at Magdalen in 1583 and introducing Copernicanism to England, but he left in disgust because 'the professors knew more about beer than Greek'.

His son Thomas described the telescope and theodolite in 1571 and 1579. Part of this description seems like a Newtonian reflecting telescope. ;   says the description of the theodolite was published in 1556.
- Charles Lutwidge Dodgson (Lewis Carroll) (1833-1898) came to Christ Church as a student 'commoner' in 1851 and remained, as 'student' and Fellow, for 47 years. He first lodged with a Rev. Jacob Ley, but soon moved into Peckwater Quad for a year. He moved to the Cloisters for about a year, then into Tom Quad, where he stayed for 6 years - his room is now the Junior Common Room. In Oct 1868, he moved into a two story apartment on the north end of the west side of Tom Quad, with access to the roof where he built a photographic studio behind the chimney stack - he stayed here until he retired in 1897. 
Carroll bought a set of fireplace tiles by William De Morgan (son of Augustus). He was mathematical lecturer in 1855-1881. Though ordained deacon in 1861, he never became a priest, but he occasionally preached, e.g. at St Mary the Virgin in the High Street and in Guildford.
Christ Church has much memorabilia of him in the Chapter House, including the Burne-Jones cartoon for the Edith Liddell memorial window .

He has a monument on the south side in St Mary the Virgin, High Street - I have a photo.  His Catoptrice et Dioptrice Sphaericae Elementa of 1695 gives the first idea of an achromatic combination of lenses - he may have had this idea from Newton.
- Robert Grosseteste (1168?-1253), philosopher and scientist, was the first (or one of the first??) Chancellor of Oxford University. He then was Bishop of Lincoln, in 1235-1253, but at that time Oxford was part of the See of Lincoln so he continued his Oxford connections.

- John Keble (1792-1866) was at Corpus Christi and was the second person to ever obtain a double first in classics and mathematics, and was elected a fellow of Oriel College, but, his calling was for the ministry and he was soon ordained and became a curate. However, his 1827 volume of poetry, A Christian Year was a great success and led to his being elected Professor of Poetry in 1831. A sermon he preached at St Mary the Virgin in 1833 is considered the beginning of the Oxford Movement, an attempt to revive the Anglican Church via an emphasis on the sacraments and ceremonies, though he did not follow the developments himself, returning to parish work. Keble College was founded in his memory - the only Oxbridge College not named for a benefactor or a Saint (using this to cover such names as Jesus, Corpus Christi, Trinity). Portrait in the Hall, bust in the Library, portrait drawing in the Senior Common Room.

- Frederick Alexander Lindemann (1886-1957), later Viscount Cherwell, was (Dr. Lee's) Professor of Experimental Philosophy and head of the Clarendon Laboratory in 1919-1956. He was a fellow of Wadham, but when the Dr. Lee's title was added to his chair in 1922, this carried with it a Studentship at Christ Church (equivalent to a fellowship at other colleges) and he moved there. Most of his work is truly in physics, but a few projects are of mathematical interest. In 1916, he analysed the spinning of airplanes and made flights to record the behaviour of a spinning plane and then demonstrated how to control such spins. FRS, 1920. He met and became friends with Churchill about 1918 and Churchill found him useful as a scientific adviser and from the mid-1930s, he served on committees dealing with air defence and radar and then became Churchill's Personal Assistant in 1939, becoming Baron Cherwell in 1942? and Paymaster-General in 1942. Working with a small and independent group, he analysed and summarised documents for Churchill and examined many aspects of the war effort, forcing departments to validate or re-examine claims, procedures and statistics which were not backed up with facts. A typical example was the analysis of German bomber strength in 1940 where the Air Ministry had substantially overestimated the number by poor arguments. One of his staff examined bombing reports and concluded that the accuracy was only a third to a quarter of what had been claimed, resulting in a major effort on improving navigational aids. It was work like this and that done by Blackett and R.V. Jones, that established operational research as an important field of applied mathematics. In 1933 and 1949, he published two papers on number theory. He left the Government when the Conservatives lost the 1945 election, but returned briefly in 1951-1953 when he supervised the creation of the Atomic Energy Authority and he served on it from its start in 1954 to his death. PC, 1943; CH, 1953; Viscount, 1956. Died in his rooms at Christ Church. 
- John Locke (1632-1704) was at Christ Church from 1652, BA in 1656, MA in 1658, became a fellow and Lecturer in Greek in 1660, Praelector Rhetoricus in 1662 and Senior Censor Of Moral Philosophy in 1663. Locke found Oxford philosophy and logic stultifying and took up medicine, not returning to philosophy until 1671. FRS 1668. He remained connected with Christ Church until his patron fell from favour and he was expelled by order of Charles II in 1684. Essay on the Human Understanding, 1690.

- Henry Gwyn Jeffreys Moseley (1887-1915) was at Trinity, in 1906-1910. He then went to Manchester to work with Rutherford, but returned to live with his mother in 1913 and work in the Electrical Laboratory, where he carried out the measurements which established the concept of atomic number in 1913-1914. In 1914, this had attracted such attention that the famous French chemist, Urbain, brought his samples of rare earths to be analysed and Moseley "... untangled in a few days conundrums that had taken chemists six generations merely to propose". There is a commemorative plaque on the family home, now in St Anne's College (thanks to Eddie Mizzi for this information and a photo). The spectrometer that he used to establish the concept of atomic number is in the Museum of the History of Science. His original graph of elements versus his measured values is in the Clarendon Laboratory.

- William Petty (1623 1687) was Vice Principal of Brasenose from 1651 and his rooms, now 106 High Street, were a gathering place in 1652 for the Oxford scientists who became the Royal Society. He taught anatomy at Brasenose, while also being Gresham Professor of Music in 1650-1651. His Political Arithmetic of 1682 was the first statistical work.  See also under: Calne, Romsey and Kerry.
- Francis Potter (1594 1678) was at Trinity. He invented an instrument for perspective drawing and a dividing machine which would do thousandths of an inch.

- Charles Pritchard (1808-1893) was a notable schoolmaster in London who took up astronomy seriously after his retirement in 1862. In 1870, he was elected Savilian Professor of Astronomy at Oxford. There he initiated and supervised the building of a new observatory, designed by himself and carried out a substantial program of observation and publication over the next 23 years. He was one of the first to recognise the advantages of photography in astronomy and applied it with success to carefully determine the parallax of nearby stars and hence their distance. He devised the wedge photometer. FRS 1840. PRAS 1866-1868. Council of the RS 1885-1887. Awarded MA by decree from New College, Oxford, in 1870 and awarded DD in 1880. Fellow of New College in 1883. RAS Gold Medal, 1886. RS Royal Medal, 1892.
- Walter Raleigh (1552-1618) was at Oriel, 1566-1569. In 1603, he donated £50 to the Bodleian and probably had a say in the donation of many books carried off during the sack of Faro, Portugal, in which Raleigh was a captain 
- Joseph Raphson (or Ralphson) ( -1715?) entered Jesus as a Fellow-Commoner in 1692 and was made MA by Royal Mandate in 1692. He had already published his Analysis aequationum universalis in 1690 which gave his simplification of Newton's iterative method for finding roots of equations.
- Robert Recorde (c1510-1558) was a student at Oxford, then a Fellow of All Souls in 1531. He then migrated to Cambridge, c1535, to establish mathematics there, then returned briefly to Oxford, c1545. ; 
- Richard of Wallingford (1292?-1336) was at Merton, c1320 . However,  says that Richard joined the Benedictine Order early in his time at Oxford, possibly to thank William, Benedictine Prior at Wallingford who had adopted him when his parents died in 1303 and sponsored his study at Oxford. As a member of an order, he could not study under a secular master and may have been at Gloucester College, a Benedictine house roughly where Worcester College is today. The only survival of this College is that the area is known as Gloucester Green. Henwood says he may have had some connection with Merton. He entered Oxford in 1308 and received his BA in 1314. He then went to join the abbey at St Albans, but returned to Oxford for further study in 1317-1327. He was licensed to lecture, but as a monk, it is unlikely that he was a fellow of any of the secular colleges.  suggests that he was director of the Benedictine house. He wrote several works on astronomical instruments and calculation, leading to his being known as the Father of English Trigonometry. His Tractatus Albionis of c1326 describes a complex geared astrolabe with four faces, but no examples are known of it. His Tractatus Horologii Astronomici appeared in 1327 and was the first detailed description of an astronomical clock - he later starting building this at St Albans (qv). He received a second degree, in theology, in 1326?.
- Stephen Peter Rigaud (1774-1839) was a student at Exeter College from 1791, fellow in 1794, BA in 1797, MA in 1799. Succeeded Hornsby as Reader in Experimental Philosophy in 1810-1839. Savilian Professor of Geometry in 1810-1827. King's Observer at Kew from 1814. Savilian Professor of Astronomy in 1827-1839. He was one of the first mathematical historians, being the first to systematically study the works of Newton, particularly the details concerning the publication of the Principia, and assisting Brewster in his biography of Newton. Brass monument in Exeter College Chapel; silhouette in the Common Room.
- Leonard James Rogers (1862- ), of the Rogers-Ramanujan identities, was born in Oxford and did a degree in music there .
- Laurence Rooke was a Fellow of Wadham, c1650.
- Earl of Rosse, see William Parsons, above.
- Prince Rupert (of the Rhine) (1619-1682), nephew of Charles I, was a Royalist general in the Civil War, but had an interest in natural philosophy and mathematics. The problem of passing a cube through another cube of the same size is known as 'Prince Rupert's problem'. See THIS LINK
There is a portrait of him in the Hall at Magdalen.See THIS LINK
- Bertrand Russell and Alys built a house at Bagley Wood, Lower Copse, in the southern outskirts of Oxford, in 1905 and lived there until 1910 .
- John Wellesley Russell - see under Balliol College in the Oxford Institutions section.
- Henry Savile (1549-1622) was a student at Brasenose 1561-1565, then a Fellow of Merton from 1565. He gave free lectures on geometry from 1570. He was Warden of Merton from 1585 and Greek tutor to Elizabeth I. In 1596 he also became Provost of Eton. Knighted in 1604. He built the Fellows' Quadrangle at Merton in 1608. He worked on the Authorized (= King James) Version of the Bible. In 1619, he founded the Savilian Chairs. He helped Bodley found the Bodleian Library. He died and is buried at Eton, but there is a large monument, with portrait bust resting on a southern hemisphere and statuettes of Ptolemy and Euclid, on the west wall of Merton Antechapel, near the south door. (I have a photo.) See THIS LINK

- Michael Scot (c1175-c1235) is believed to have studied at Oxford.
- John Sinclair was at Trinity College.
- Charles Singer was a student of Gunther. In 1914-1920, he got the Bodleian to provide a 'Science Room' for himself and other workers in the history of science. University Lecturer in the History of Biological Sciences in 1920, the first academic post in the history of science at Oxford, and probably in the UK. However, he was unable to form a department and soon left Oxford for London where he established the first department of the history and philosophy of science at University College London. 
- Adam Smith was at Balliol.
- Henry John Stephen Smith (1826-1883) was a student at Balliol and then succeeded Frederick Temple as Mathematics Lecturer there . He was later Savilian Professor of Geometry and a Fellow of Corpus Christi. He was second Curator of the University Museum from 1874 and lived in an adjacent house (qv ubder University Museum). He is commemorated on a plaque in Balliol Chapel. He was buried in St Sepulchre's, in the Jericho area of Oxford, but the original burial records were destroyed in a flood and a 1988 survey and transcription of the legible gravestones did not record our Smith (information from Eddie Mizzi).
- James Lewis Smithson (1765-1829) was at Pembroke. He left £100,000 to the United States government 'to found at Washington an institution for the increase and diffusion of knowledge among men'. 
- Frederick Soddy (1877-1956) was at Merton. He became Dr. Lee's Professor of Chemistry in 1919. He was at Oxford when he received the 1921 Nobel Prize for Chemistry for his discovery of isotopes, though this work was done at McGill with Rutherford.
Somerville College, founded 1879, is named for Mary Somerville.
- Rev. Dr. William Archibald Spooner (1844-1930), Warden of New College, was described thus by his biographer: "All his life, Spooner looked like a white-haired baby. He was small, pink-faced and an albino, with a disproportionately large head and very shortsighted pale blue eyes." Arnold Toynbee said "He looked like a rabbit, ...." It is said he was the model for the White Rabbit in Dodgson's Alice's Adventures in Wonderland.
- William Spottiswoode was a lecturer in mathematics at Balliol. He went into the family printing business but continued as an enthusiastic mathematician, becoming President of the Royal Society. He is commemorated on a plaque in Balliol Chapel.
- James Stirling (1692-1770) was a student at Balliol from 1710 but lost his scholarship because he refused to take the oath of allegiance to George I in 1715 and never graduated.  says he published a book at Oxford in 1717. 
- Thomas Strode (1642 1688), an author of mathematical books, was at University College .
- Richard Swineshead (or Suiceth) (c1325-1365) was at Merton, c1345. He wrote De Latitudinibus Formarum. 
- Frederick Temple (1821-1902), was a mathematical lecturer at Balliol, but went into the Church, becoming Bishop of London in 1885-1896 and Archbishop of Canterbury from 1896. He published a 'proof' of the Four Colour Theorem in 1889 . There is a portrait of him in Balliol's Hall.
- Alexander Thom, the pioneer archaeo-astronomer, was Professor of Engineering Science at Oxford in the mid 20th century.
- Edward Charles Titchmarsh (1899-1963) was at Balliol, though his education was interrupted by the first war. Succeeded Hardy as Savilian Professor of Geometry, in 1931.

- J. Twysden (1607-1688) was at University College. He wrote several mathematical books. 
- James Ussher (1581-1656) was at Oxford in 1642-1645, presumably supporting the King. He was already Archbishop of Armagh, but his notorious determination of the age of the world was announced later, in 1650. Portrait in the Bodleian. 
- Oswald Veblen exchanged places with Hardy in 1928-1929 .
- John Wallis (1616-1703) was Savilian Professor of Mathematics from 1649 to 1703. (Contrary to some reports he was not at Queen's College - that was his namesake, the county historian (1714-93) ) He was the first President of the Oxford Philosophical Society in 1683. He is buried in the University Church of St Mary the Virgin in the High Street. There is a portrait bust monument on the south wall near the screen. The inscription is fading - I have suggested that perhaps the Mathematical Institute could have it repainted. There is a portrait by Kneller in the Examination Schools. See THIS LINK.
The Bodleian also has a bust of Wallis. ; 
- Lancelot Lionel Ware (1915-2000), co-founder of Mensa, is commemorated by a plaque outside the lodgings he occupied at the time he and Roland Berrill founded Mensa in 1946 .
- Seth Ward (1617-1689) was a Fellow of Wadham and Savilian Professor of Astronomy in 1649, later at Trinity, becoming President of Trinity in 1659. He went on to be Bishop of Exeter and of Salisbury. At Wadham, he occupied the room with the oriel window over the College entrance, later occupied by Wren.
- John Henry Constantine Whitehead (1904-1960) was a student and a Fellow at Balliol in 1933-1946, becoming Waynflete Professor in 1947-1960, which led to his transfer to New College. He was the main founder of the Mathematical Institute. There is a plaque to him in the Antechapel of Balliol.
- Andrew Wiles (1953- ) was an undergraduate at Merton.
- John Wilkins (1614-1672) was born in Oxford. He was at New Inn Hall and Magdalen Hall, then became Warden of Wadham (1648-1659) and then Master of Trinity College Cambridge in 1659 and later Bishop of Chester in 1668. His A Discourse Concerning a New World and Another Planet of 1638 was one of the first serious attempts at popularization of science. His Mathematical Magick. Or, the Wonders that may be Performed by Mechanical Geometry. ... Being one of the most easie, pleasant, useful, (and yet most neglected) part of Mathematicks of 1648 was the first textbook on mechanics in English and its ideas were systematically investigated in the following decades by Hooke et al. He left his telescope and burning glass to Queen's when he departed from Oxford.  It was in his Wadham rooms that the precursor of the Royal Society met in the late 1640s. He later was the first Secretary of the RS in 1672. Portrait in the Bodleian . See THIS LINK
- Edmond Wingate was at Queen's College to 1614 .
- Christopher Wren (1632-1723) was a student at Wadham from 1649 (or earlier?), graduating in 1651 and MA in 1653. He occupied the 'Astronomy Room' - the big room with the oriel window at the top of the tower over the College gate in Wadham, formerly occupied by Ward - so Wren was probably here from 1661 to 1673 and presumably produced many of his plans here. Wadham has a wooden clock face reputedly presented by Wren when he left  above the chapel door . While at Wadham, he originated the idea of intravenous injections in 1656  and blood transfusion (in 1657) and he removed the spleen of a puppy, showing that it was not a vital organ . He was a pioneer microscopist and made drawings of the brain for Thomas Willis' Cerebri Anatome of 1664. He also invented a 'diplographic' pen to write in duplicate and designed a bee-hive .
He was elected a Fellow of All Souls in 1653 and was Bursar for a time. All Souls has an 1658 sundial by him ;  dates it to c1653 and has a photo (or possibly by him ) on the wall of the Codrington Library facing North Quad. See THIS LINK
Gill says Wren was pleased with its accuracy and quotes him 'one may see to a minute what it is o'clock'.
All Souls also has Wren's pre-fire plans for St Paul's (drawn in the Astronomy Room at Wadham), the plans for the Wren Library at Trinity College, Cambridge, the plans for the unbuilt mausoleum for Charles I at Windsor, and his death mask . Evelyn visited him in 1664 and found he had been watching a transit of Venus from the top of the Old Schools Tower . There is a bust of Wren in the Codrington Library of All Souls and another in the Ashmolean Museum. There is a portrait and a window in the Hall of All Souls. In 1657, he left to become Gresham Professor in London. In 1661-1673, he was Savilian Professor of Astronomy, but he spent most of a year in Paris during 1665-1666 and I suspect he didn't reside much in Oxford after the Great Fire of London in 1666 and even less after being appointed Surveyor of the King's Works in 1669. In 1662, he devised an apparatus of suspended balls to study impact - Newton's Cradle?? - which Newton explicitly acknowledges as the demonstration of the laws of collision . He also devised instruments for recording the weather and for grinding lenses .
Wren designed a number of buildings in Oxford.  summarises the buildings and architects of Oxford. The Sheldonian Theatre of c1663-1669 was Wren's first major commission and required great mathematical engineering for the 70' by 80' hanging ceiling. This was built for Gilbert Sheldon who had been removed from the Mastership of Wadham in 1648, and restored in 1659, but soon became Bishop of London. The first we know of the plans was when Wren exhibited a model to the Royal Society in 1663, so planning must have started sometime sooner. The basic idea was adapted from the drawings of the Theatre of Marcellus in the 16th-century book of Sebastiano Serlio. (Serlio's book has the first, though inadvertent, appearance of a vanishing area puzzle.) Serlio also had described flat hanging roofs using beams shorter than the span of the roof and Wallis had studied such structures and exhibited models to the Royal Society. See THIS LINK
Wren used a different form - the vertical truss - and analysed it in more detail.  See THIS LINK
Wren also built the north wing of the main or garden quad at Trinity in 1665 (the first Italian style building in Oxford, partially extant, though both the building and the quad have been much changed) and "certainly" made suggestions for the Chapel. He built the top or cupola of Tom Tower at Christ Church in 1681-1682. He may have had some input to the design of Queen's College Library or its front quadrangle, which was done by his pupil Hawksmoor in the 1690s. The Chapel of Queen's was also built by Hawksmoor in 1714, but it is said to be based on a c1682 design by Wren. The Old Ashmolean, now the Museum of the History of Science, has been attributed to Wren, but this is certainly spurious. The nearby buttresses for the Bodleian, in Exeter gardens, are due to his advice . The Chapel and Library of Brasenose College, built in 1656-1666, are also attributed to Wren.
