Google has made it a beautiful tradition to put a spotlight on often forgotten or under-recognized scientists, artists and other great minds. Today, on the occasion of what would have been her 127th birthday, that honor goes to Danish seismologist Inge Lehmann. The doodle (an artistic reinvention of Google’s logo on its homepage) shows an Earth split in two, with its bright core shining in the middle to recognize Lehmann’s pioneering discovery that the Earth has both an inner and an outer core. She came to this realization by studying earthquakes, and it forever changed the way scientists have studied the planet. While she was educated at a progressive, mixed-gender school (unique at the time), she often faced gender discrimination later on in her career, and was once quoted as having said: “You should know how many incompetent men I had to compete with — in vain.” The groundbreaking seismologist received the highest honor of the American Geophysical Union, the William Bowie medal, in 1971, and passed away at 105 in 1993.
