WebInge Lehmann was a Danish seismologist–a physicist who studied waves in the Earth’s crust–active in the mid-20th century. She is most remembered for her theory of the Earth’s solid inner core, based on her work on seismic waves caused by earthquakes. Inge Lehmann was born in Copenhagen, Denmark on May 13, 1888. WebNot until 1926 did Harold Jeffreys refute the arguments for solidity and establish that the core is liquid. In 1936 Inge Lehmann discovered the small inner core. K. E. Bullen argued, on the basis of plausible assumptions about compressibility and density, that the inner core is solid. Attempts to find seismic signals that have passed through ...
WebIn 1936 she published the paper that sealed her place in the history of geophysics. Known simply as “P’ (P-prime),” the paper suggested a new discontinuity in the seismic structure of the Earth, now known as the Lehmann discontinuity, a region that divides the core into inner and outer parts.
