About one month before we graduated, we had a banquet to say "thank you" to our professors. The after dinner program included some singing (which I directed) for the teachers. Our president came to the banquet too, as he had been a chemist before becoming the president. The surprising aspect was that all our female classmates put on some make-up and got more dressed-up than usual, which had never been seen before by their male counterparts. Another first at this party was that everyone in the graduating class (a total of thirty) was there! What a night!
A photographer was there to take the official picture of students and teachers of the Chemistry Department, 1961.
