Matsusaburo Fujiwara

In 1908 Fujiwara and Tsuruichi Hayashi (1873–1935) were appointed professors at Tohoku University in Sendai.

[2] After his return in February 1912, Fujiwara worked closely with his colleague Tsuruichi Hayashi, who in 1911 founded the Tohoku Mathematical Journal.

Fujiwara was an important contributor to the development of the Mathematical Institute of the University of Tokyo.

After the death of his colleague Hayashi in 1935, Fujiwara intensively studied the history of wasan, i.e. traditional Japanese mathematics.

While Takagi was considered the more original researcher (on the basis of contributions to class field theory), Fujiwara was known for his scholarship.
