Answer
Max Perutz attended Cambridge University in the 1930s. He studied chemistry and biochemistry there, and he was a member of the famous Cavendish Laboratory. Perutz's work at Cambridge helped him to develop the technique of X-ray crystallography, which he used to study the structure of proteins. Perutz's work on proteins led to the discovery of the structure of hemoglobin, the protein that carries oxygen in the blood.
