Walter Maurice Elsasser (March 20, 1904 – October 14, 1991) was a German-born American physicist, a developer of the presently accepted dynamo theory as an explanation of the Earth's magnetism.
He proposed that this magnetic field resulted from electric currents induced in the fluid outer core of the Earth.He revealed the history of the Earth's magnetic field by the study of the magnetic orientation of minerals in rocks.
He was also the first to suggest that the wave-like nature of matter might be investigated by electron scattering experiments using crystalline solids.
The Olin Hall at the Johns Hopkins University has a Walter Elsasser Memorial in the lobby.
