Inge Lehmann was a Danish seismologist and geophysicist, best known for her discovery of the Earth's inner core. Born on May 13, 1888, in Copenhagen, Denmark, she made significant contributions to our understanding of the Earth's structure. In 1936, Lehmann proposed that the Earth has a solid inner core surrounded by a liquid outer core, based on the analysis of seismic waves generated by earthquakes.
