Inge Lehmann was born on May 13, 1888, in Copenhagen, Denmark, to Alfred Lehmann, a professor of psychology, and Ida Sophie Tørsleff. She grew up in an unusually progressive household for the era; her father was a pioneering experimental psychologist, and the family valued education for both sons and daughters equally.
Lehmann attended one of the first coeducational schools in Denmark, run by Hanna Adler, aunt of physicist Niels Bohr. This early exposure to an environment where boys and girls were taught identically, with no distinction in academic expectation, profoundly shaped Lehmann's confidence and ambitions in a period when women were largely excluded from serious scientific careers.
Her birth marks the beginning of a life that would eventually transform the field of seismology and geophysics. Lehmann would go on to become one of the most important Earth scientists of the twentieth century, discovering the solid inner core of the Earth in 1936. Her upbringing in Copenhagen, steeped in intellectual rigor and a relatively egalitarian view of education, laid the groundwork for a scientific career that would span more than six decades and break significant barriers for women in the physical sciences.
