Professor Yoshiaki Maeda, a co-editor of this volume, kindly asked me to prepare an article on academic genealogy of my brother Shoshichi Kobayashi. In the olden times, it would have been a formidable task for any individual who is not in the same field as the subject mathematician to undertake a genealogy search. Luckily, the “Mathematics Genealogy Project” (administered by the Department of Mathematics, North Dakota State University)  and Wikipedia  which document almost all notable mathematicians, provided the necessary information for me to write this article. Before I undertook this study, I knew very little about Shoshichi’s academic genealogy, except for his advisor
at the University of Tokyo and his Ph.D. thesis advisor
at the University of Washington, Seattle.
