In 1952 I was a second year student of a senior high school in Kanazawa. One day the teacher of our physics class took us out to a nearby transformer substation to look at equipment there. Then the teacher took a photo of us. I am the third person from left in the second row. The rightmost person in the front row is probably the head of the substation. Note that the ratio of the number of boys to that of girls in the physics class was 9 to 1, although the total number of boys in the school was nearly the same as that of girls.
