Inge Lehmann Google Logo Marks 127th Birthday Of Woman Who Discovered Earth’s Inner Core
She was the first woman to receive a William Bowie medal - the highest honor awarded by the American Geophysical Union.
Today’s Google Doodle honors Inge Lehmann, the female seismologist who discovered the earth’s inner and outer cores. Designed by Doodler Kevin Laughlin, the animated logo uses a glowing orb to represent Lehmann’s discovery.
Born in Østerbro, Denmark, Lehmann was appointed the head of the department of seismology at Denmark’s Geodtical Institute in 1928.
After intensive research of earthquakes and seismic waves, Lehmann authored a paper in 1936 proposing that the Earth’s center consisted of both a solid inner core surrounded by a liquid outer core and separated by what is now referred to as the “Lehmann Discontinuity.”

From the Google Doodle blog: “Inge used deduction and evidence to discover something unseeable. Today’s Doodle sheds light on her powerful but invisible discovery.”
Her research was confirmed in 1970 with the introduction of more sensitive seismographs capable of detecting seismic waves deflecting off the earth’s solid core.
Among her credits, Lehmann was awarded the Gold Medal of the Danish Royal Society of Science and Letters and named a Fellow of the Royal Society. She was the first woman to receive the William Bowie medal – the highest honor given by the American Geophysical Union – and was recognized by the Seismological Society of America.
