A short biography of M. IWASAKI (born: Dec. 22,1954, Nishinomiya, Japan; deceased; Sept. 23, 1980, same place; odonatologist, Ph.D. student of Kyoto University) is followed by his odonatological bibliography (1974-1981). On September 23, 1980, Masamichi Iwasaki passed away at the early age of twenty-five. He was a Ph.D. student of Kyoto University and had been working devotedly on calopterygid behaviour. His premature death cannot be too much deplored.
