The scientist we are looking for this time studied mathematics, yet received the highest honor in chemistry. He or she developed equations that are used to determine molecular structures directly from X-ray crystallographic data. This breakthrough led to an enormous increase in the number of successful structure determinations and had a large influence on chemical research.

Our scientist’s work had important applications in drug development, and the institute for medical research in the United States where our scientist worked was renamed in his or her honor.
