Cover Story: X-ray analyses of crystals of biological molecules have revolutionised our understanding of biological processes in humans and other organisms. Blundell’s personal history records the excitement of revealing the crystal structures of a protein hormone, insulin, in the 1960s, and of HIV protease, allowing rational design of AIDS antivirals in 1980s. It describes his involvement in preserving the historic centre of Oxford and in advancing racial diversity and gender balance. The use of crystals and structure-guided design in Astex Pharma in Cambridge led two cancer drugs into the market, and in academia, to finding drug leads for tuberculosis and leprosy―diseases that kill millions worldwide. Crystals and crystallography continue to contribute to drug design and provide a successful example of academia–industry collaboration. View this paper
