This exhibition explores the intriguing creations of the Festival Pattern Group - a unique project at the 1951 Festival of Britain involving X-ray crystallographers, designers and manufacturers. At the instigation of Dr Helen Megaw, a leading Cambridge scientist, diagrams of atomic structures inspired an eclectic array of patterns on curtains, wallpapers, carpets, lace, dress fabrics, ties, plates and ashtrays.X-ray crystallography was one of the most exciting branches of post-war science, with far-reaching applications in chemistry, physics, biology and mineralogy. By studying X-ray diffraction photographs of crystals, scientists could calculate the arrangement of atoms within molecules. The resulting diagrams provided the inspiration for the Festival Pattern Group. 'From Atoms to Patterns' shows the diagrams next to the designs.
