Leading criminologists were inferring criminal tendencies from eyebrow type well into the late 19th century in Europe. Specifically, Cesare Lombroso's[1] theory of Anthropological Criminology listed, amongst a number of other characteristics such as large ears and (if I remember my criminology class) supernumerary nipples: "bushy eyebrows, tending to meet across nose"[2] as a physiognomic feature useful in identifying "criminal man."
