British physicist who invented the x-ray spectrometer, a device used to measure x-ray wavelengths. With his son, the physicist Sir William Lawrence Bragg (1890-1971), he developed the technique of x-ray crystallography, used to determine the atomic structure of crystals. Father and son were awarded a joint Nobel Prize for physics in 1915 for this work. |
