Yale University’s School of Architecture was in the midst transition when Louis Kahn joined the faculty in 1947. The post-war years at Yale trended away from the school’s Beaux-Arts lineage towards the avant-garde, and Modernist principles brought over from European architects. When the University called for a new wing for its existing Venetian Gothic style Art Gallery Building (1928), they obviously had no choice but to make a statement for the future of the school. Architecture professor Louis Kahn worked with Anne Tyng, who was both a professional partner and his “muse”, who heavily influenced his works, including here where she designed the concrete tetrahedral slab ceiling at the interior galleries. As a professor and practicing architect, Kahn hoped for students and visitors would engage with the building, even interior spaces often overlooked design-wise, such as the stairwells. While the facades are fairly minimal in design details, because the attention was paid to the interiors, which provide protection from natural light while also allowing for large floor plates for customizable exhibitions. The structure is Yale’s first true Modernist building on a campus which soon after was dominated by some of the country’s most iconic examples of the style.
