James Gardner Oldroyd (born 1921 died
22 November 1982 "The Times" November 25, 1982 page 26 "Deaths"] ) was Britishmathematician and notedrheologist .He formulated theOldroyd-B model to describe theviscoelastic behaviour ofnon-Newtonian fluid s.Life
Oldroyd was born in 1921 and educated at
Bradford Grammar School , andTrinity College, Cambridge . On graduation, during theSecond World War , he worked for theMinistry of Supply . After the war he joined the Research Laboratory ofCourtaulds . In 1946 he married Marged Katryn Evans.C. Petrie (1983) "Rheologica Acta" vol 22 no 1 pp 1-3 "Obituary"] In 1953 be became professor ofmathematics at theUniversity of Wales, Swansea until 1965 and head of the Applied Mathematics department from 1957. In 1965 he moved toLiverpool University , becoming head of the Department of Applied Mathematics and Theoretical Physics in 1973 until his death."The Times" December 7, 1982 page 14, "Professor J. G. Oldroyd"] He died 22 November 1982, and was survived by his wife Katryn and three sons.Work
In 1950 he published a paper "On the Formulation of Rheological Equations of State"J. G. Oldroyd (1950)"Proceedings of the Royal Society of London". Series A, Mathematical and Physical Sciences, Volume 200, Issue 1063, pp. 523-541] which has been described as "probably the most important single paper in theoretical rheology"A. B. Metzner (1981) "Bulletin of the British Society of Rheology" Volume 24, number 1] as it established the basic requirements for mathematical models of rheology. For this and other major papers he received international recognition, including the Gold Medal of the British Society of Rheology, and a tribute issue of its Bulletin on his sixtieth birthday.
