Richard Dugdale published his findings in 1877 as "The Jukes: A Study of Crime, Pauperism, Disease, and Heredity." Dugdale created the pseudonym "Jukes" as a label for a clan "so despised by the reputable community that their family name had come to be used generically as a term of reproach." The Jukes' world was mired in crime and poverty, shot through with the habit of illicit sex. Dugdale's litany of evils listed "crime, pauperism, fornication, prostitution, bastardy, exhaustion, intemperance, disease and extinction" as other common features of their lives.
