Born in 1864, William Thorpe Jones was educated at Southwell Grammar School and St George's, Brampton. He became a pupil of C. Hodgson Fowler, F.S.A., F.R.I.B.A., and later worked with R. K. Freeman, F.R.I.B.A. before setting up in practice on his own account in 1892. In the following year he became architect to the University of Durham, and he was the moving spirit behind the programme of restoration work carried out on Durham castle in the 1920's and 1930's, acting as its architect until his death in 1932. His publications included the account of the castle in The Victoria History of County Durham , vol. 3 (1928), 64-93. In that year he was awarded an honorary M.A. degree by the university. His practice was located at 43 North Bailey, Durham.
