It was a day with dark foreboding clouds. Suddenly, just as I walked into the snack machine room, there was a sudden massive downpour. I saw an elderly gentleman struggling to close the window. I went over and helped. He thanked me. We shook our heads together at the suddenness of the storm.
After he walked out, a classmate said, "Dude, that was Max Zorn, of Zorn's Lemma."
Apparently at the time, he was retired emeritus, but apparently he still came to the office from time to time.
