Her active research career as a seismologist began in 1928, continued well into the 1970s, and earned her the reputation as the grande dame of modern seismology.Fonte:fotoDespite her international success, Inge Lehmann was never well known outside the geophysical science community in Denmark. Her contribution to science was first officially acknowledged in Denmark on 15 May 2017 when a monument in her honour was revealed by Denmarks Minister for Higher Education and Science, Sren Pind. The monument is situated in front of the University of Copenhagen, next to Niels Bohr, making her the first female scientist to be commemorated by the University. The artist Elisabeth Toubro chose an abstract form for the monument that celebrates what mattered for Inge Lehmann: Her scince rather than herself as a person. Born in a time when few women could holdsenior scientific positions, Inge Lehmann had an extraordinary career: In 1928, she was appointed Head of the Seismic Section at the Danish Geodetic Institute, where she published evidence for the existence of the Earths inner core in 1936. After her retirement in 1953, she continued her work at research institutions in the USA, and in 1964, she proved a velocity discontinuity at a depth of 220 km, known today as the Lehmann Discontinuity.During Inge Lehmanns lifetime, seismology developed from a small, isolated discipline to a large, well-funded research area. This growth took place against the backdrop of the Cold War with its political and military agendas. Seismology attracted special interest because it provided tools for the detection of nuclear weapons tests.Her private archive was handed over to the Danish National Archive in 2015 and it contains more than 4,000 letters and documents relating to her research. As an important scientist in her field, shecorresponded with many of the leading seismologists of the time. Few of her private letters have survived.Inge Lehmann has often been portrayed as a trailblazing female scientist, unwilling to accept discrimination in her pursuit of an academic career. However, her personal archive at the Danish National Archive shows that Inge Lehmann had to accept restrictionsin her academic career due to her gender, and only by being pragmatic about her situation did she succeed in establishing herself as a professional scientistThe celebration of her achievement by the University of Copenhagen was the highpoint of several years of public interests beginning with a 2015 documentary on Danish national television about Inge Lehmann s life and discoveries, followed by a Google doodle on May 13, 2015 in celebration of her 127-years birthday, and the naming of several Danish streets after her. Finally, the Carlsberg Found is funding a two-year research project, by this author, to write her biography.According to the artist Elisabeth Toubro, the Lehmann monument shows a wave slicing through the sculpture and striking a round core that causes it to change direction. The body of the sculpture is cleaved in two, suggesting an earthquake
