This thesis argues for an interdisciplinary examination of the origins and subsequent appearance of the Wassermann blood test, the first test developed for detecting syphilis, in eugenics initiatives and medicolegal mandates. When this seemingly impartial medical tool intersected with preexisting social and cultural biases regarding syphilis its story became one of blood purity initiatives for the preservation and proliferation of white normativity. Reframing the Wassermann as more than a passive medical tool highlights how ostensibly impartial medical processes can produce institutional violence in masculinized spaces of control. While the Wassermann offered a source of hope for protecting against syphilitic infection, in application, the serodiagnostic tool served as a source of scientific validation when misapplied as a quantifiable method for justifying medicolegal interventions in the 20th century US. This examination traces the bioethical legacy of the Wassermann from its 1906 development in Berlin to its appearance in eugenics-based legal mandates in the US. Through an analysis of scientific publications and court records at archives across the East Coast this paper centers those who didn't benefit from the Wassermann and investigates how scientific authority derived from an imperfect diagnostic test was harnessed to reproduce and reinforce the sociocultural biases that linger today.
