In 1936, she theorized from existing seismic data an inner core with physical properties distinct from the outer core's and that Earth's core is not a single molten sphere. Seismologists, who had not been able to propose a workable hypothesis for the observation that the P-wave created by earthquakes slowed down when it reached certain areas of the inner Earth, quickly accepted her conclusion. She studied mathematics at the University of Copenhagen and University of Cambridge. In 1928, she passed her exam in geodesy and accepted a position as state geodesist and head of the department of seismology at the Geodetical Institute of Denmark. She moved to the USA for several years and collaborated with Maurice Ewing and Frank Press on investigations of Earth's crust and upper mantle. During this work, she discovered another seismic discontinuity, which lies at depths between 190 and 250 km and was named for her, the Lehmann discontinuity, etc.) - http://en.wikipedia.org/wiki/Inge_Lehmann
