evidence: Transcript from an interview with Tasuku Honjo [...] Tasuku Honjo: There are several levels. As general science the first incident I was enchanted or charmed by the natural science is the very tiny tiny ring around the Saturn which I watched through the telescope at the elementary school. That was the first. I got very much interested, I wanted to be an astronomer and I read many books. But then later switched to medicine because I read the biography of Hideyo Noguchi. And the second very critical moment, maybe the time to come back to Japan, so it was another big choice in my life whether I stay in United Stated, keep going and many people advised to stay, but I decide to go back to Japan. That was -74, another type of turning point. Both cases I was fortunate that my decision was correct or correct because I made something, retrospective. [...] Tasuku Honjo: For my science I have so many important mentors or advisors. The first mentor was Osamu Hayaishi, who discovered oxygen, gas oxygen directing cooperation into the organic compounds, gave my solid background in science and also international theory. Science has to be international, it is not a local thing. And the next person who opened my eye to the molecular immunology is Donald Brown of Carnegie Institution of Washington. Without him I never go into this particular field and then I went to Philip Leder’s laboratory where I actually started this antibody diversification. So those three are very important during my scientific career.
