Inge Lehmann
Inge Lehmann (13 May 1888 – 21 February 1993) was a Danish seismologist and geophysicist who is known for her discovery in 1936 of the solid inner core that exists within the molten outer core of the Earth. She also discovered the seismic discontinuity in the speed of seismic waves at depths between 190 km (120 mi) and 250 km (160 mi), which is named the Lehmann discontinuity after her. Lehmann is considered to be a pioneer among women and scientists in seismology research.
