J.M. Cowley and A.F. Moodie awarded the first Ewald Prize

In 1987 it was announced that the first Ewald Prize had been awarded to Professor J.M. Cowley (Tempe, Arizona, USA) and Dr A.F. Moodie (Clayton, Victoria, Australia) for their outstanding achievements in electron diffraction and microscopy. They carried out pioneering work on the dynamical scattering of electrons and the direct imaging of crystal structures and structure defects by high-resolution electron microscopy. The physical optics approach used by Cowley and Moodie takes into account many hundreds of scattered beams, and represents a far-reaching extension of the dynamical theory for X-rays, first developed by P.P. Ewald.

The presentation of the Ewald Prize was made during the Perth Congress Opening Ceremony in August 1987.
