Hayashi Tsuruichi

Hayashi Tsuruichi ( Japanese 林 鶴 一 ; born June 13, 1873 in Tokushima , Tokushima Prefecture , † October 4, 1935 in Matsue , Shimane Prefecture ) was a Japanese mathematician.

Hayashi attended the third high school in Tokyo and studied mathematics at the Imperial University of Tokyo under Fujisawa Rikitarō (1861-1933) and Kikuchi Dairoku (1855-1917). In 1897 he graduated. A fellow student was Takagi Teiji . Hayashi taught mathematics at the Higher Normal School in Tokyo and later at the newly established Imperial University of Kyoto . In 1907 he became professor at the newly founded University of Tōhoku (opened in 1911), as a colleague of Fujiwara Matsusaburō . There he was director of the mathematical institute, which he created with Fujiwara based on the model of the mathematical institute in Göttingen.

In 1912 he founded the Tohoku Mathematical Journal, one of the most important mathematical journals in Japan and the first internationally distributed mathematics journal in Japan.

He dealt with Japanese history of mathematics ( Wasan ), where he was in competition with Mikami Yoshio . His collected essays on it appeared posthumously . He also wrote mathematics textbooks for secondary schools.

In 1924 he became a member of the Leopoldina .
