Inge Lehmann
Definition
Inge Lehmann was a Danish seismologist who discovered the inner core of the Earth. She was the first person to realize that the Earth's inner core is solid, not liquid.
Lehmann was born in Copenhagen, Denmark, in 1888. She studied physics and mathematics at the University of Copenhagen, and she received her PhD in 1925.
After graduating, Lehmann worked as a seismologist at the Danish Geodetic Institute. She studied earthquake waves and used them to map the interior of the Earth.
In 1936, Lehmann noticed that some earthquake waves were refracted, or bent, as they passed through the Earth's interior. This could only happen if the Earth's inner core was solid.
Lehmann's discovery was a major breakthrough in seismology. It helped scientists to better understand the structure of the Earth and its evolution.
