Inge Lehmann (
May 13,
1888-
February 21,
1993), Fellow of the
Royal Society (London) 1969, was a
Danish seismologist who, in
1936, argued that the Earth must not only have a molten interior, but a solid core at the center, which deflects
P waves. She also wrote a book called
P, which dealt with P waves and other aspects of seismography.
