Interview with P.P. Ewald
This film was recorded at the International Crystallography Conference, 1965, Melbourne, Australia, by the CSIRO Film Unit in collaboration with the Australian Academy of Science. If you are at all interested in the history of crystallography, and of science in general, I think you will find this video to be 15 well spent minutes.
This film was made possible with support from UNESCO, the International Council of Scientific Unions, the Australian Academy of Science, the International Union of Crystallography, the International Union of Pure and Applied Physics, the International Atomic Energy Agency and the University of Melbourne.
