Herbert Hauptman, who shared the 1985 Nobel Prize in Chemistry, has died, reports The New York Times. He was 94. Hauptman, a mathematician, worked with chemist Jerome Karle, a classmate from City College, to develop equations to interpret X-ray crystallography films, an advance that greatly sped up the work of analyzing molecular structures. "I don't think there's a single pharmaceutical that's been developed in the last 30 years that hasn't been studied using derivations of what Dr. Hauptman and his colleagues won the Nobel Prize for," says Eaton Lattman, chief executive of the Hauptman-Woodward institute, where Hauptman worked.
