Wymer’s D.C. is an online collection of the hand-drawn maps, notes and (especially) photographs of John P. Wymer (1904-1995), who in a four-year period between 1948 and 1952 systematically photographed and documented the streets of Washington, D.C., taking thousands of pictures and drawing and describing the city, which he divided into 57 equal sections. The photos are displayed via an interactive map that overlays them over modern-day Google Street View imagery. The site is the brainchild of Jessica Richardson Smith, who as an intern stumbled across the Wymer collection in the holdings of the Historical Society of Washington, D.C. as an intern and made the online collection part of her M.A. thesis work, and her husband, software engineer Thomas Smith.
