Perutz, Max Ferdinand (1914–2002)
Austria-born British biochemist who studied X-ray
diffraction by proteins. In 1953 he discovered that adding a heavy atom,
such as one of gold or mercury, to each molecule of hemoglobin
produces a slightly different diffraction pattern. By this means he demonstrated
the structure of hemoglobin, for which he shared the 1962 Nobel Prize in
Chemistry with John Kendrew who, by a similar
method, discovered the structure of myoglobin.
