The book entitled "Pioneer of Science Journalism: Biography of Jun Ishiwara"  was published recently, and I read a review of it . The reviewer, Atsuko Tsuji, first writes as follows:
The name "Jun Ishiwara" seems to be unfamiliar to many people. So, the title of the book "Pioneer of Science Journalism" might be somewhat misleading.
As noted at the beginning by the author, he was one of the best theoretical physicists. In the early twentieth century, he first published first papers in Japan on relativity and quantum theory, which brought about a revolution in physics, and led discussion in the country.
This is the work in which Ishiwara (1881–1947) generalized the quantum rule independently of W. Wilson and A. Sommerfeld.
It is even a surprise that the name of such a scientist is little known.The love affair of Ishiwara, who had a wife and children, became a scandal, and he retired from the professorship at Tohoku Imperial University at the age of 42. Is this related to the unfamiliarity of him to people? After retirement, he pulled himself from research and became a person to discuss and communicate about science.
