captured her imagination because of the intricate and wide-ranging effect it has in the body. However, at this stage X-ray crystallography had not been developed far enough to cope with the complexity of the insulin molecule. She and others spent many years improving the technique. Larger and more complex molecules were being tackled (see timeline below) until in 1969 – 35 years later – the structure of insulin was finally resolved. But her quest was not finished then. She cooperated with other laboratories active in insulin research, gave advice, and travelled the world giving talks about insulin and its importance for diabetes.
