摘要

A long handwritten letter by Professor W.H. Bragg, dated 16 December 1912 and addressed to the Vice-Chancellor of the University of Leeds (an extract of which is presented in this article), provides an authoritative record of the progress in X-ray crystallography from the beginning of the Bragg's father and son collaboration in August 1912-December 1914. The collaboration began at the village of Cloughton on the North Yorkshire coast but hitherto the house itself had not been identified. As a result of an historical investigation initiated by the writer and with the help of members of the Bragg and Barran families and the Cloughton Local History Group, it is now identified as Whin Brow', the summer home of Henry and Rosalie Barran, close friends of William and Gwendoline Bragg. A plaque at Whin Brow', commemorating the new science of X-ray crystallography', was unveiled by Mr Charles Bragg (great-grandson of William Bragg) on 5 July 2013.
