The area was named Bellevue by Thomas Grafton Addison, who purchased the land in 1795 and built a mansion there. Old city maps and land permit records going back to 1880s designated this area of SW as labeled "Bell View"/"Bellevue"--"beautiful view" in French. Most residential development occurred in the 1940s and 1950s, with some in the 1960s. Once a thriving commercial hub, Bellevue declined during the mass exodus of the middle class in the 1960s. It is on the cusp of revitalization. The most recent addition to the neighborhood is the $15M world class, David Adjaye designed edifice to replace the former Washington Highlands Library. The DC Board of Library Trustees voted in July 2011 to rename the new building Bellevue after the neighborhood where it is properly located. Over $150M in commercial mixed-use development is in the pipeline along South Capitol and Atlantic Streets, the heart of the Bellevue Business District.
