"Sexual Crimes Among the Southern Negroes" by George Frank Lydston delves into the controversial and racially charged topic of sex crimes in the American South during the late 19th century. Written from the perspective of early sexology, the book reflects the vintage sexology views of its time, intertwining pseudoscience with prevailing racial biases. Lydston attempts to analyze the causes of sexual deviance among Southern African Americans, often attributing criminal behavior to racial inferiority, a belief common in that era. While the work is now widely discredited, it remains a significant, albeit disturbing, artifact of how sex crime was understood through the lens of vintage sexology and racial prejudice.
