Dr. Hiroshi Hashimoto, Emeritus Professor of Shizuoka University, passed away on 26th February 1915, at the age of 90. Chironomid workers within and beyond Japan must never forget that three entomologists, Drs Masaaki Tokunaga, Hiroshi Hashimoto and Manabu Sasa, have contributed greatly to the progress of chironomid taxonomy, morphology, ecology and public health.
