Danish seismologist Inge Lehmann is remembered for her groundbreaking discovery of the Earth’s solid inner core and molten outer core, using seismic waves. While she initially studied math, she later deviated to seismology, with a focus on ascertaining earthquake epicenters. The William Bowie Medal-winning scientist died at age 104.
