Norio Kato

Norio Kato (Japanese: 加藤 範夫, Kato Norio, March 10, 1923 – April 5, 2002) was a Japanese physicist and crystallographer. He was known for his contributions in diffraction topography and the dynamical theory of diffraction, including the validation of the Pendellösung effect and extensions to account for realistic scattering conditions.

Education and career Kato was born in Shanghai, China at Nagoya University, where he received a MSc in 1946 and a doctoral degree in physics in 1954. In 1950, Kato worked at the Kobayasi Institute of Physical Research (now part of RIKEN) under Shoji Nishikawa.

Kato returned to Japan and Nagoya University in 1960 as an associate professor of Applied Physics and became a full professor in 1961. He was a member of the executive committee of the International Union of Crystallography from 1968 to 1972. He is a recipient of the Chunichi cultural award in 1976. He received the Ewald Prize in 1993 for his contribution to the dynamical theory of diffraction and diffraction topography. He was president of the Crystallographic Society of Japan in 1982 and president of the International Union of Crystallography from 1978 to 1981, the first Asian to lead the international organization.
