The Tohoku Mathematical Journal was started in July 1911, one month prior to the first lecture at the College of Science, after a period of preparation that began with the foundation of Tohoku Imperial University on June 22, 1907. Professor Tsuruichi HAYASHI, who with Professor Matsusaburo FUJIWARA was one of the founding professors of the Mathematical Institute of the College of Science, provided his own private funds for the publication of the journal. Among the first generation of faculty members at the College of Science, Professor Fujiwara, Assistant Professor Tadahiko KUBOTA, Assistant Kinnosuke OGURA and Physics Professor Jun ISHIHARA cooperated with Professor Hayashi in editing the journal. As Professor Fujiwara later commented in the Obituary Note for Professor Hayashi published in Tohoku Math. J., First Series, Vol. 41, (1935-1936), pp.265-289, " To found a new journal, periodically issued, in such a time, was a very bold enterprise. His foresight and audacity only could do this. The publication of the Tôhoku Mathematical Journal marked a striking epoch in the history of mathematics in Japan." From the start, the journal was a truly international research journal accepting qualified original articles written in Japanese, English, German, French, or Italian from throughout the world. The financial burden on Professor Hayashi must have been considerable. President Masataro SAWAYANAGI of the Tohoku Imperial University tried to alleviate this burden by arranging for the university to purchase copies which were then donated to other universities and learned societies throughout the world. On the advice of the Board of Audit of the Japanese Government, the management of the journal was transferred to the university, although Professor Hayashi continued to serve as Chief-Editor until the end of his life. Due to the Second World War, the publication of the journal had to be suspended, and Volume 49 in 1943 was the last issue in the First Series. After the war the publication of the journal was resumed, and Volume 1 in the Second Series was published in 1949. In the Second Series, only original research articles written in English, German or French are accepted, whereas the First Series contained review articles as well as articles written in Japanese on traditional Japanese mathematics ("wazan", sometimes pronounced "wasan"). Publication of the First Series was somewhat irregular, but on average two volumes were published each year. In the Second Series,
