The latest volume in the <i>Defining Moments in American Photography</i> series, <i>Trauma and Documentary Photography of the FSA</i> proposes that we reconsider the work of the Farm Security Administration and its most beloved photographers in light of various forms of trauma in the 1930s. The authors offer new ways to understand this body of work by exploring a more variable idea of documentary photography than what the New Dealers proposed. Taking a critical look at the FSA photography project, they identify its goals, biases, contradictions, and ambivalences, while discerning strikingly independent directions among its photographers. Blair and Rosenberg discuss how, in the hands of socially minded photographers seeking to address and publicize suffering, photography and trauma mixed. In the volatility of that mixture, they argue, competing ideas for documentary took shape. Among the key figures studied here are some of the most beloved in American photography, including Walker Evans, Ben Shahn, and Aaron Siskind.
