I still remember very clearly the first time that I met Professor Iwasawa. It was in 1967 when he had just become a faculty member at Princeton University. I was a second year graduate student and had decided that I was ready to take the General Examination. Students were not told in advance which faculty members were to be on their examining committee. I had hoped that Professor Iwasawa would be on my committee and, on the day of the examination, when I was told that the committee was waiting for me in his office, I knew that my hope would be fulfilled. It was at that time that I first met him.
