The seismologists Inge Lehman had an outstanding contribution to the understanding of the structure and composition of our planet, specially through the discovery of the Earth’s inner core.

Studying wave patterns, Inge Lehmann theorized that the centre of the Earth had a solid inner core with a liquid outer core.

She was awarded the William Bowie medal in 1971, and there is an award from the Advancing Earth and Science (AGU) named in her honour.
