Abstract
Chiba and Kajiyama's "The Vowel" was a milestone in the study of vowel production. This work was made possible on the background of advancement of science in this country. Evolution of acoustical sciences in these days is reviewed. Completion of this monograph should have opened days of glory in phonetic and acoustic research in Japan. But the Pacific War broke out before publication and Japanese science was isolated from the international scientific community. Further tragedies of war on sciences and scientists and post-war developments are described.
