Jung-Hwa Kim (Architecture) delivered a virtual oral presentation for a Library Company of Philadelphia and Historical Society of Pennsylvania fellowship colloquium on June 5, 2023. The fellowship-awarded research, “The Design and Use of the Wanamaker’s Department Store Rooftop in Philadelphia, 1910 to the 1920s,” showed how the Wanamaker’s in Philadelphia developed their flat roof into a roof garden, “Athletic Field,” with a rise of urban entertainment and the public in the early 20th century.
