Winterthur was designed with entertaining in mind. When Henry Francis du Pont hosted guests, he allowed no one in the dining room until 8:30 p.m., when the doors were thrown open and the meal was presented with the theatricality of a stage production.

The table's glasses and silver caught the flickering of the candle's flames, as the dim lighting from the room's candelabras and candlesticks created a dramatic elegance. The dishes, linens, servingware, and centerpieces were always chosen with meticulous care, as was the seating arrangement. A Winterthur dinner party was one guests would always remember.
