Technology And The Logic Of American Racism: A Cultural History Of The Body As Evidence (critical Research In Material Culture)

The color of blood is red, not black or white. Yet blood, along with fingerprints, skin, and color is commonly cited as objective evidence of racial identity. Drawing on this concept of "evidence", Sarah Chinn deftly interweaves analyses of the history of science, popular culture, forensic technology and literary texts to examine how racial identity has been constructed in the United States over the past century.

Chinn begins her provocative study with an analysis of Mark Twain's Pudd'nhead Wilson to explore how new ways of reading bodies developed at the end of the nineteenth century. Using Twain's story of a light-skinned slave baby exchanged with his white master, Chinn analyses growth of the American scientific passion for turning people into numbers and bodily characteristics into racial "identities". Contrasting Nella Larsen's Passing, Wallace Thurman's The Blacker the Berry, and the notorious Rhinelander miscegenation scandal of the 1920's, Chinn goes onto explore the meanings of skin color and racial identity during the Jazz Age.

Chinn further investigates the meaning of "blood" through the American Red Cross' racial segregation of blood donated by African Americans and Japanese Americans.

Finally, as technology (e.g. DNA testing) increasingly allows the body to be "read", Chinn argues that it is simply the latest enactment of a discourse that seeks to cement racial, gender, and class identities as empirical rather than constructed and capable of change. However, the announcement of genetic evidence that Thomas Jefferson was the father of his slave Sally Hemmings' children offers an alternative vision: that DNA can show Americans that their bodies are evidence not ofexclusivity but of multiplicity.
