The depigmentation theory received notable support from later anthropologists, thus in 1947 Melville Jacobs noted: "To many physical anthropologists Nordic means a group with an especially high percentage of blondness, which represent a depigmentated Mediterranean". In her work "Races of Man" (1963, 2nd Ed. 1965) Sonia Mary Cole went further to argue that the Nordic race belongs to the "brunette Mediterranean" Caucasoid division but that it differs only in its higher percentage of blonde hair and light eyes. The Harvard anthropologist Claude Alvin Villee Jr. also was a notable proponent of this theory, writing: "The Nordic division, a partially depigmised branch of the Mediterranean group." "Collier's Encyclopedia" as late as 1984 contains an entry for this theory, citing anthropological support.
