Erich Mendelsohn's buildings, erected throughout Germany between 1920 and 1932, epitomized architectural modernity for his countrymen. In this study, Kathleen James examines his department stores, office buildings and cinemas, the downtown counterparts to the famous housing projects built during the same years in Frankfurt and Berlin. Demonstrating the degree to which their dynamic presence stemmed from Mendelsohn's attention to their consumer-oriented functions, James shows Mendelsohn to be more than an Expressionist, as he is usually characterized.
