Thomas Stephens Davies FRS FRSE(1795–1851) was a British mathematician.

Mathematician person with an extensive knowledge of mathematics

A mathematician is someone who uses an extensive knowledge of mathematics in his or her work, typically to solve mathematical problems.



He was born on 1 January 1795. [1]

Davies made his earliest communications to the Leeds Correspondent in July 1817 and the Gentleman's Diary for 1819. He subsequently contributed largely to the Gentleman's and Lady's Diary, Clay's Scientific Receptacle, the Monthly Magazine, the Philosophical Magazine , the Bath and Bristol Magazine, and the Mechanics' Magazine. Davies was elected a Fellow of the Society of Antiquaries of London, 19 March 1840

Gentleman's Diary or The Mathematical Repository was an almanac published at the end of the 18th century in England, including mathematical problems.

<i>Philosophical Magazine</i> scientific journal established in 1798

The Philosophical Magazine is one of the oldest scientific journals published in English. It was established by Alexander Tilloch in 1798; in 1822 Richard Taylor became joint editor and it has been published continuously by Taylor & Francis ever since.

Davies's early acquaintance with Dr. William Trail, the author of the Life of Dr. Robert Simson, materially influenced his course of study and made him familiar with the old as well as with the modern professors of geometry. He became a fellow of the Royal Society of Edinburgh in 1831, and he contributed several original and elaborate papers to its Transactions. He also published Researches on Terrestrial Magnetism in the Philosophical Transactions, Determination of the Law of Resistance to a Projectile in the Mechanics' Magazine, and other papers in the Cambridge and Dublin Mathematical Journal, the Civil Engineer, the Athenæum, the Westminster Review, and Notes and Queries.

William Trail (1746–1831), British mathematician and Church of Ireland clergyman

Rev Dr William Trail or Trail DD FRSE MRIA LLD was an 18th/19th century Scots-born mathematician, remembered for his mathematical text books. For the majority of his life he served church duties in Northern Ireland.

Geometry branch of mathematics that measures the shape, size and position of objects

Geometry is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer.

Royal Society of Edinburgh academy of sciences

The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity, operating on a wholly independent and non-party-political basis and providing public benefit throughout Scotland. It was established in 1783. As of 2017, it has more than 1,660 Fellows.

In 1831 he was elected a Fellow of the Royal Society of Edinburgh his proposer being John Shoolbred. [2] In April, 1833 he was elected a Fellow of the Royal Society. [3]

Fellow of the Royal Society Elected Fellow of the Royal Society, including Honorary, Foreign and Royal Fellows

Fellowship of the Royal Society is an award granted to individuals that the Royal Society of London judges to have made a 'substantial contribution to the improvement of natural knowledge, including mathematics, engineering science and medical science'.

In 1834, he was appointed one of the mathematical masters in the Royal Military Academy at Woolwich. Among the numerous subjects that engaged his attention were researches on the properties of the trapezium, Pascal's hexagramme mystique, Brianchon's theorem, symmetrical properties of plane triangles, and researches into the geometry of three dimensions. His new system of spherical geometry preserves his name in the list of well-known mathematicians.

Royal Military Academy, Woolwich military academy in Woolwich, in south-east London

The Royal Military Academy (RMA) at Woolwich, in south-east London, was a British Army military academy for the training of commissioned officers of the Royal Artillery and Royal Engineers. It later also trained officers of the Royal Corps of Signals and other technical corps. RMA Woolwich was commonly known as "The Shop" because its first building was a converted workshop of the Woolwich Arsenal.

Woolwich district in South East London, England

Woolwich is a district of south-east London, England, within the Royal Borough of Greenwich. Originally a town in Kent, it has been part of the London metropolitan area since the 19th century. In 1965, most of the former Metropolitan Borough of Woolwich became part of Greenwich Borough, of which it remains the administrative centre.

Trapezoid convex quadrilateral with at least one pair of parallel sides

In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid in American and Canadian English but as a trapezium in English outside North America. The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides. A scalene trapezoid is a trapezoid with no sides of equal measure, in contrast to the special cases below.

His presentation "On the Velocipede" in May 1837 is extant as a manuscript and gives a vivid testimony of the rise and putting down of the draisines aka hobby-horses. He must have been an early hobby-horse rider himself according to that (transcript in The Boneshaker #108(1985) pp. 4–9 and #111(1986) pp. 7–12))

His death, after six years of illness, took place at Broomhall Cottage, Shooter's Hill, Kent, on 6 January 1851, when he was in his fifty-seventh year.

Shooters Hill district in South East London, United Kingdom

Shooter's Hill is a district in South East London within the Royal Borough of Greenwich. It borders the London Borough of Bexley. It lies north of Eltham and south of Woolwich. With a height of 132 metres (433 ft), it is the highest point in the Borough of Greenwich and one of the highest points in London. Shooter's Hill also gives its name to the A road which passes through east to west and is part of the A207 road, the A2 road, and also Watling Street.

Kent County of England

Kent is a county in South East England and one of the home counties. It borders Greater London to the north west, Surrey to the west and East Sussex to the south west. The county also shares borders with Essex along the estuary of the River Thames, and with the French department of Pas-de-Calais through the Channel Tunnel. The county town is Maidstone.


Davies edited the following works:

Of the above, Solutions of the Principal Questions is the most important work. It is a large octavo of 560 pages, enriched with four thousand solutions on nearly all subjects of mathematical interest and of various degrees of difficulty.

A long catalogue of Davies's writings is printed in the Westminster Review, April 1851, pp. 70–83.
