Thomas WrightManuscripts

Archive Collection

Scope and Content

This collection largely consists of cosmological, astronomical and meteorological drafts and notes, most, but not all of which are in the hand of Wright himself. They include a sequel to his Original theory, or new hypothesis of the universe , in which he repudiated his earlier explanation of the stars, and instead placed the sun at the centre of visible creation; (an edition of this sequel was publishedby Dr Michael Hoskin in 1968). The collection also includes works on comets, longitude, and the divine nature of visible creation. Among the meteorological material are weather diaries kept by Wright at Westerton, Hartlepool, and Bishop Auckland,Co. Durham, and tables of weather records for the Coventry area, 1724-1733, possibly based on observations of Henry Beighton. Much of the collection dates from the period of Wright's retirement to Byers Green, from 1755, after twenty years on thefringes of high society, surveying estates, giving lessons in mathematics and the physical sciences to noble ladies, and publishing works on astronomy, architecture and antiquities. There is no material in this collection on Wright’s architecturaland garden designs.

Administrative / Biographical History

Thomas Wright was born at Byers Green, Co. Durham. In 1730, at the age of 20, he set up his own school in Sunderland, where he taught mathematics and navigation, and sold mathematical instruments. Through the good offices of the Earl ofScarbrough, his instrument the pannauticon was approved by the Lords of the Admiralty, and the central period of his career was spent in London and in the country houses of aristocratic patrons. A polymath, Wright achieved distinction not only as amathematician, astronomer and instrument maker, but also as an architect and garden designer, and antiquary. In his best known and most influential work, An original theory or new hypothesis of the universe (London, 1750), Wright explained the appearance of the Milky Way as an optical effect due to our immersion in what locally approximates to a flat layer of stars, anidea which was taken up, transformed and greatly elaborated by Immanuel Kant, after reading an abstract of Wright's work in a Hamburg periodical. Largely self-taught, Wright never quite succeeded in breaking into the scientific establishment, buthis career illustrates how an able man with scientific interests could make his way by lecturing, teaching the children of his patrons, and furthering their architectural and gardening projects. In retirement he returned to Byers Green to prosecutehis studies, and built a small observatory tower at Westerton nearby.

Arrangement

Wright himself grouped and regrouped and numbered and renumbered many of these papers, and in some cases supplied them with title-pages with a view to publication. When acquired by Dawsons in 1966 they were in chaotic disorder. They were sortedfor Dawsons by Dr. Michael Hoskin, and his arrangement has been retained with only minor modifications to associate related papers which had become separated. Other such relationships may still remain unidentified, and at some points the order inwhich the sheets have been numbered is unavoidably arbitrary, given the nature of the material.

The University Library also has extensive holdings of publications about Wright, and a collection of Wrightiana (cuttings, photocopies, photographs, slides etc.) providing backgroundinformation on his life and works, for which an online catalogue is available.
