Paul Peter Ewald
From Wikipedia, the free encyclopedia
Paul Peter Ewald (January 23, 1888 - August 22, 1985) was a U.S. (German-born) crystallographer and physicist, who received his Ph.D. in 1912,[1] under Arnold Sommerfeld, at the University of Munich. He was a pioneer of the X-ray diffraction methods. He was also the eponym of Ewald construction and the Ewald sphere. He was the father-in-law of Hans Bethe, also a student of Sommerfeld.
Paul Peter Ewald was awarded the Max Planck medal in 1978.
Ewald wrote several books on the mechanics of solids and liquids, one of which, The Physics of Solids and Fluids (London, Blackie and Son, 1930) was in collaboration with the physicists Th. Pöschl and Ludwig Prandtl. (Also see Prandtl number, an important dimensionless measure of the ratio of the diffusion of momentum and of heat in fluid dynamics.)
