Bragg's X-ray Spectrograph and accessories

Made:
1930-1970
maker:
William Henry Bragg

Bragg's X-ray Spectrograph and accessories, used to detect X-rays before cameras. Made by Pye, serial number 10168, it is one of perhaps only six made, and the forerunner of modern diffractometers. In 1915 Sir William Henry Bragg was awarded the Nobel Prize for Chemistry jointly with his son William Lawrence "for their services in the analysis of crystal structure by means of X-rays". Sir William was also Quain Professor of Physics UCL, 1915-23, and director of the Royal Institution, 1923-1942; Lonsdale worked with him at both places.

From a collection relating to the X-ray crystallography research carried out by Dame Kathleen Lonsdale at University College London.
