in which the animal-like competitive reproductive behavior was seen as a legacy of ancestral human evolution reflecting in every social relation, as per the Freudian interpretation, and hence the liberation of sexual behavior a mean to social revolution. Mead's Coming of Age in Samoa The 1928 publication of anthropologist Margaret Mead's Coming of Age in Samoa brought the sexual revolution to the public scene, as her thoughts concerning sexual freedom pervaded academia. Mead's ethnography focused on the psychosexual development of adolescents in Samoa. She recorded that their adolescence was not, in fact, a time of "storm and stress" as Erikson's stages of development suggest, but that the sexual freedom experienced by the adolescents actually permitted them an easy transition from childhood to adulthood. Mead's findings were later criticized by anthropologist Derek Freeman, who investigated her claims of promiscuity and conducted his own ethnography of Samoan society. Unwin's Sex and Culture Kinsey and Masters and Johnson In the late 1940s and early 1950s, Alfred C. Kinsey published two surveys of modern sexual behavior. In 1948 Alfred C. Kinsey and his co-workers, responding to a request by female students at Indiana University for more information on human sexual behavior, published the book Sexual behavior in the Human Male. They followed this five years later with Sexual behavior in the Human Female. These books began a revolution in social awareness of, and public attention given to, human sexuality. It is said that public morality severely restricted open discussion of sexuality as a human characteristic, and specific sexual practices, especially sexual behaviors that did not lead to procreation. Kinsey's books contained studies about controversial topics such as the frequency of homosexuality, and the sexuality of minors aged two weeks to fourteen years. Scientists working for Kinsey reported data that led to the conclusion that people are capable of sexual stimulation from birth. Furthermore, Kinsey's method of researching sexuality differs significantly from today's methods. Kinsey would watch his research subjects engage in sexual intercourse, sometimes engaging with his subjects as well. He would also encourage his research team to do the same, and encouraged them to engage in intercourse with him, too. These books laid the groundwork for Masters and Johnson's life work. A study called Human Sexual Response in 1966 revealed the nature and scope of the sexual practices of young Americans. Popular culture The Playboy culture In 1953, Chicago resident Hugh Hefner founded
