Inge Lehmann - Journey to the (Solid) Center of the Earth

Think of the layers of the Earth as an onion, a slice of cake, or better yet, a Ferrero Rocher; a chocolate with a wafer outer crust, a creamy filling and a solid hazelnut in the center. If this analogy is true, then Inge Lehmann is the Danish seismologist who discovered the hazelnut in the center of the earth.

Ok ok, it's not a gigantic hazelnut, but it's still a solid core! In 1936 Inge Lehmanndeciphered the Earth's hidden structure by studying seismic waves from earthquakes, something no one else had noticed.

But breaking scientific ground wasn’t the only challenge she faced. As a woman in a field dominated by men, Lehmann had to push through skepticism and barriers to have her work recognized. 

Follow us in episode twenty of The Inventing HerStory Podcast to learn all about Inge's life and discoveries. And the next time you hear about the mysteries of our planet’s depths, remember Inge Lehmann: scientist, trailblazer, and the woman who revealed Earth’s inner core.
