Horatio Scott Carslaw

Dr Horatio Scott Carslaw FRSE LLD (12 February 1870, Helensburgh, Dunbartonshire, Scotland – 11 November 1954, Burradoo, New South Wales, Australia) was a Scottish-Australian mathematician. The book he wrote with his colleague John Conrad Jaeger, Conduction of Heat in Solids, remains a classic in the field.

Early life and education Carslaw was born in Helensburgh, Scotland, the son of the Rev Dr William Henderson Carslaw (a Free Church minister) and his wife, Elizabeth Lockhead. He was a Fellow of Emmanuel College, Cambridge and worked as a lecturer in Mathematics at Glasgow University when, in late 1902, he moved to Australia.

In 1903, upon the retirement of Theodore Thomas Gurney, Carslaw was appointed Professor and the Chair of Pure and Applied Mathematics in the now School of Mathematics and Statistics at the University of Sydney. He retired in 1935 to his house in Burradoo where he produced most of his best work.

Personal life and death Carslaw married Ethel Maude Clarke (daughter of Sir William Clarke, 1st Baronet revised and enlarged 3rd edn. 1930, published under the title Introduction to the theory of Fourier's series and integrals The Elements of Non-Euclidean Plane Geometry and Trigonometry, London 1916 with John Conrad Jaeger: Operational methods in applied mathematics, 1941, 1948 with Jaeger: Conduction of Heat in Solids, Oxford 1947, 1959
