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. She was awarded the Tagea Brandt Rejselegat twice, in 1938 and 1967.
