William Bragg, Leeds-based professor of physics, designed this instrument to study the structure of crystals with his son, Lawrence Bragg, also a renowned physicist. Its invention earned them a joint Nobel Prize for Physics in 1915. Understanding the properties of crystals, from common salt and diamonds to complex organic compounds, has allowed innumerable advances in chemistry, physics, materials science, biology and medicine.
