Inge Lehmann

Inge Lehmann was a pioneering Danish seismologist who made significant contributions to our understanding of Earth's internal structure. In 1936, she proposed the existence of a solid inner core within the Earth's molten outer core, based on studies of seismic waves generated by earthquakes. Her work helped refine models of Earth's layers and improved our knowledge of geophysical processes. Lehmann's insights have been crucial in the fields of geophysics and tectonophysics, influencing how scientists study the Earth's composition and behavior, and she is celebrated as one of the first female leaders in the field.
