Karl Bernhard Zoeppritz, German geophysicist and seismologist (b. 1881)

Karl Bernhard Zoeppritz (22 October 1881 – 20 July 1908) was a German geophysicist who made important contributions to seismology, in particular the formulation of the Zoeppritz equations.

These equations relate the amplitudes of P-waves and S-waves at each side of an interface, between two arbitrary elastic media, as a function of the angle of incidence and are largely used in reflection seismology for determining structure and properties of the subsurface.
