Race Life of the Aryan Peoples
Race Life of the Aryan Peoples is a two-volume book written by Joseph Pomeroy Widney, at the time chancellor of the University of Southern California, published in New York by Funk & Wagnalls in 1907. Written before the era of modern genetic science, it purports to tell the history of the Aryan race, a hypothesized race which, in the late 19th and early 20th centuries, was commonly thought to exist and was regarded as descended from the original speakers of Proto-Indo European.
