Isabella Karle (1921-2017) was a pioneer in the scientific field of crystallography. Her work on molecular structures had a sweeping influence across many scientific fields by allowing, for example, scientists to study nerve transmissions and aiding chemists in synthesizing pest repellents.
Donald Ames joined the Manhattan Project as a G.I. at the University of Chicago in 1943. Ames worked under Nobel Prize chemist Glenn Seaborg at the Metallurgical Laboratory, where he helped determine the chemical properties of plutonium and developed a rapid method for measuring the radium concentration in solutions.
