[Photography] Carnegie Survey of the Architecture of the SouthNoted architectural photographer Frances Benjamin Johnston (1864-1952) created a systematic record of early American buildings and gardens called the Carnegie Survey of the Architecture of the South (CSAS). This collection, created primarily in the 1930s, provides more than 7,100 images showing an estimated 1,700 structures and sites in rural and urban areas of Virginia, Maryland, North Carolina, South Carolina, Georgia, Alabama, and Louisiana, and to a lesser extent Florida, Mississippi, and West Virginia.
