The late Darleane Hoffman was an Iowa State grad, visionary scientist

Before the late Darleane Hoffman discovered ways to study rare elements and isotopes and advanced understanding of nuclear fission, she was a student at Iowa State University, where she found her passion for chemistry.

Named one of the "50 most important women in science," Hoffman became a renowned nuclear chemist, despite not having a chance to study chemistry until she arrived in Ames. The small-town Iowan quickly developed a strong interest in the field, inspired by her female professor.
