Sue Lawley's castaway this week is Dr Max Perutz. When he left Austria in 1936 to study at Cambridge, his fellow students dismissed his ambition to decipher the structure of the protein haemoglobin as 'mad'. No-one had seriously attempted to map a molecule that was made up of 10,000 atoms. Twenty-two years later he was successful. It was an achievement that earned him and his colleague John Kendrew the Nobel Prize in Chemistry in 1962 - and has since contributed to the study of blood diseases like sickle cell anaemia and Huntington's disease.
