The first page of the obituary  carries a group photo. On looking at it, I thought as follows: The Japanese scientist there seems similar to Kazumi, but is perhaps another physicist in superconductivity. I might have seen a photo of the latter before at a Web page about John Bardeen Prize 2006 (Kazumi won the award that year, but the other scientists got the same prize or a similar one at the same time). I wanted to confirm my thought by looking at that Web page again, but could not find it. Thus, I sent an e-mail message to Naoki Toyota, Professor at Tohoku University. He is a former colleague of mine and ex-student of Kazumi. In the message to him I wrote, "That isn't Kazumi, is that?"
But alas! His answer showed definitively that my thought was wrong. He wrote that, judging from the look and the shape of the body, the Japanese person in the photo was Kazumi. He also referred to another picture at a Web site . This picture was of the same occasion as that in Physica B but from a different angle. The person at the center of the picture has eyes full of curiosity, and surely I recognize him as Kazumi. Then, the Japanese person in the photo of Physica B must also be Kazumi, though the former's look and shape of the body are a little different from those of the latter I remember from earlier days.
I again looked for the Web page about Bardeen Prize and found it this time . The page also gives the description of H. Kamerlingh Onnes Prize and a few other ones, with three photos. The caption lies below the photos, showing up only when we scroll the page down. I reminded myself of the following: Without scrolling the page, I first thought that the photos were of the scene of the awarding of Bardeen Prize and that the second person from right in the rightmost photo was Kazumi. However, looking at the expanded photo, I found that the person was a little similar to, but not, Kazumi. Then I returned to the original page and read the caption to learn that the person was Hidenori Takagi from Tokyo. He shared Onnes Prize with two scientists. (There are no photos of the three recipients of John Bardeen Prize, maybe because it is the Web page of Princeton University, to which N. Phuan Ong, one of the recipients of Onnes Prize, belonged but no recipients of Bardeen Prize did.)
Now I can explain the cause of my mistake as follows: When I browsed the Bardeen Prize Web page earlier, the enlarged photo disproved my belief that the Japanese person in the photo was Kazumi. This was a little traumatic happening to me. The vague memory of this made me commit the error together with the following curious fact: Kazumi's look with a gentle smile as in the photo of Physica B seems solemner (more like some other professor with dignity) than his look when he is serious. However, I also have to think this way: I have been a constant discoverer of errors in other persons' publications, but made an error this time in identifying the image of a good friend. Is this due to my aging?
