I was saddened to read about the recent death of Professor Robert Mark (On the Campus, May 15). I have thought a lot about him in the wake of the recent fire at Notre Dame. Surely he would have grieved the terrible destruction there, and yet I suspect that a part of him would have been excited by the opportunity that this will provide to investigate some of the questions surrounding its construction and reconstruction throughout the centuries. Even though I was a biology major who went on to med school, his course in structure and Gothic architecture remains one of my favorite memories of Princeton. When  I later made it to France, my experience of Chartres, Notre Dame, and the Sainte-Chapelle was greatly enriched by what  I had learned from Professor Mark.
