Vaulted ceilings and elegant architectural details are evident in this photo of Upper Madison Hall, known as “Commons” to generations of Princetonians. When Madison was constructed in 1917, it had the capacity to feed the entire ­freshman and sophomore classes, as well as juniors and seniors who were not in eating clubs. Commons was incorporated into the Rockefeller-Mathey complex when the ­University’s residential-college system was created in the 1980s. Larry French took the photo, which accompanied PAW’s March 22, 1989, feature story “Chow’s On!” — as did a recipe (yield: 800 servings) for Cantonese Chicken Breasts, described as “an undergraduate favorite.”
