Julian Schwinger at Harvard before June, '67 --- remembered by a star-struck and frequently confused undergrad*

I was an undergraduate at Harvard when Julian Schwinger received the Nobel
Prize.  The following year, I took his course on Source Theory.  I will
share some memories of those days, and some of my interactions with Schwinger's work and
students in the years that followed.  I will also pass on some stories of
the very early days from some of my Harvard colleagues
