For this NDI Project, I plan to visit a variety of American cities (including Chicago, Detroit, Los Angeles, Phoenix and Portland) to enrich a new monograph project on Co-op City, a neighborhood in New York City. I will explore their neighborhoods, and consult with urban planners and architects to find out about the current challenges and plans for the future. I will also consult with academics, who have participated in this dialogue between academia and urban planning. Support from the NDI will allow me to move in two new directions: First, it will help me step from the familiar waters of German history in the early twentieth century to situate my new research project on Co-op City in an interdisciplinary and interregional (American) context. Second, it will help me engage in a dialogue with urban planners about issues of common concern.
