I just had the pleasure of giving an hour and a half long talk last week entitled, “Preserving DC’s Jazz Age Architectural Heritage.” It focused on buildings dating to the 1920s and 30s that I have worked on here in Washington, DC at Quinn Evans with a focus on ambassadors' residences and cultural facilities. The lecture was a combination of architectural history and preservation architecture case studies, essentially a virtual tour of DC. The talk focused on eight buildings built during the Jazz Age. These buildings included: Australian Ambassador's Residence, National Academy of Sciences, Yuma Study Center, DAR Constitution Hall, Former Japanese Ambassador's Residence (now Chancery Annex), Belgian Ambassador's Residence, Main Interior Building, and Ecuadorian Ambassador's Residence. It started with an overview of the 19th century (beginning with the L'Enfant plan) and the early decades of the 20th century (discussion of the McMiIllan Plan) and numerous historic buildings that Quinn Evans (and myself) have worked on, many in the Classical Revival style. The context of the growth of Washington, DC was provided throughout the chronological discussion of historic buildings and their architectural projects.
