Margaret Mead in the context of "Norbert Wiener"

Franz Uri Boas (July 9, 1858 – December 21, 1942) was a German-American anthropologist and ethnomusicologist. He was a pioneer of modern anthropology who has been called the "Father of American Anthropology". His work is associated with the movements known as historical particularism and cultural relativism.

Studying in Germany, Boas was awarded a doctorate in 1881 in physics while also studying geography. He then participated in a geographical expedition to northern Canada, where he became fascinated with the culture and language of the Baffin Island Inuit. He went on to do field work with the indigenous cultures and languages of the Pacific Northwest. In 1887 he emigrated to the United States, where he first worked as a museum curator at the Smithsonian, and in 1899 became a professor of anthropology at Columbia University, where he remained for the rest of his career. Through his students, many of whom went on to found anthropology departments and research programmes inspired by their mentor, Boas profoundly influenced the development of American anthropology. Among his many significant students were A. L. Kroeber, Alexander Goldenweiser, Ruth Benedict, Edward Sapir, Margaret Mead, Zora Neale Hurston, and Gilberto Freyre.

Primitive communism is a way of describing the gift economies of hunter-gatherers throughout history, where resources and property hunted or gathered are shared with all members of a group in accordance with individual needs. In political sociology and anthropology, it is also a concept (often credited to Karl Marx and Friedrich Engels), that describes hunter-gatherer societies as traditionally being based on egalitarian social relations and common ownership. A primary inspiration for both Marx and Engels were Lewis H. Morgan's descriptions of "communism in living" as practised by the Haudenosaunee of North America. In Marx's model of socioeconomic structures, societies with primitive communism had no hierarchical social class structures or capital accumulation.

The idea has been criticised by anthropologists as too ethnocentrically European a model to be applied to other societies, whilst also romanticising non-European societies. Anthropologists such as Margaret Mead argue that private property exists in hunter-gatherer and other "primitive societies" and provide examples that Marx and subsequent theorists label as personal property, not private property.

Ray L. Birdwhistell (September 29, 1918 – October 19, 1994) was an American anthropologist who founded kinesics as a field of inquiry and research. Birdwhistell coined the term kinesics, meaning "facial expression, gestures, posture and gait, and visible arm and body movements". He estimated that "no more than 30 to 35 percent of the social meaning of a conversation or an interaction is carried by the words." Stated more broadly, he argued that "words are not the only containers of social knowledge." He proposed other technical terms, including kineme, and many others less frequently used today.

Birdwhistell had at least as much impact on the study of language and social interaction generally as just nonverbal communication because he was interested in the study of communication more broadly than is often recognized. Birdwhistell understood body movements to be culturally patterned rather than universal. His students were required to read widely, sources not only in communication but also anthropology and linguistics. "Birdwhistell himself was deeply disappointed that his general communicative interests and goals were not appropriately understood." Collaborations with others, including initially Margaret Mead and Gregory Bateson, and later, Erving Goffman and Dell Hymes had huge influence on his work. For example, the book he is best known for, Kinesics and Context, "would not have appeared if it had not been envisaged by Erving Goffman" and he explicitly stated "the paramount and sustaining influence upon my work has been that of anthropological linguistics", a tradition most directly represented at the University of Pennsylvania by Hymes.

The sexual revolution, also known as the sexual liberation, was a social movement that challenged traditional codes of behavior related to sexuality and interpersonal relationships throughout the Western world from the late 1950s to the early 1970s. Sexual liberation included increased acceptance of sexual intercourse outside of traditional heterosexual, monogamous relationships, primarily marriage. The legalization of "the pill" as well as other forms of contraception, public nudity, pornography, premarital sex, homosexuality, masturbation, alternative forms of sexuality, and abortion all followed.

The term "first sexual revolution" is used by scholars to describe different periods of significant change in Western sexual norms, including the Christianization of Roman sexuality, the decline of Victorian morals, and the cultural shifts of the Roaring Twenties. Sexual revolution most commonly refers to the mid-20th century, when advances in contraception, medicine, and social movements led to widespread changes in attitudes and behaviors around sex. The sexual revolution was influenced by Freud's theory of unconscious drives and psychosexual development, Mead's ethnographic work on adolescent sexuality in Samoa, Unwin’s cross-cultural studies, and the research of Kinsey and later Masters and Johnson, all of which challenged traditional beliefs about human sexuality.

Taʻū is the largest inhabited island in the Manuʻa Islands in American Samoa and the easternmost volcanic island of the Samoan Islands. In the early 19th century, the island was sometimes called Opoun.

Taʻū is well known as the site where the American anthropologist Margaret Mead conducted her dissertation research in Samoa in the 1920s, after which she published her findings in a work titled Coming of Age in Samoa. Ta’u also has the highest mountain in American Samoa, Mount Lata, as well as 21 square kilometers (8.3 sq mi) of National Park lands, and 3.9 km (1.5 sq mi) of waters separated by some of the tallest sea cliffs in the world.

Ruth Fulton Benedict (June 5, 1887 – September 17, 1948) was an American anthropologist and folklorist.

She was born in New York City, attended Vassar College, and graduated in 1909. After studying anthropology at the New School of Social Research under Elsie Clews Parsons, she entered graduate studies at Columbia University in 1921, where she studied under Franz Boas. She received her Ph.D. and joined the faculty in 1923. Margaret Mead, with whom she shared a romantic relationship, Marvin Opler and Vera D. Rubin were among her students and colleagues.

Second-order cybernetics, also known as the cybernetics of cybernetics, is the recursive application of cybernetics to itself and the reflexive practice of cybernetics according to such a critique. It is cybernetics where "the role of the observer is appreciated and acknowledged rather than disguised, as had become traditional in western science". Second-order cybernetics was developed between the late 1960s and mid 1970s by Heinz von Foerster and others, with key inspiration coming from Margaret Mead. Foerster referred to it as "the control of control and the communication of communication" and differentiated first-order cybernetics as "the cybernetics of observed systems" and second-order cybernetics as "the cybernetics of observing systems".

The concept of second-order cybernetics is closely allied to radical constructivism, which was developed around the same time by Ernst von Glasersfeld. While it is sometimes considered a break from the earlier concerns of cybernetics, there is much continuity with previous work and it can be thought of as a distinct tradition within cybernetics, with origins in issues evident during the Macy conferences in which cybernetics was initially developed. Its concerns include autonomy, epistemology, ethics, language, reflexivity, self-consistency, self-referentiality, and self-organizing capabilities of Complex Systems, such as in Complexity Theory (extenuating to the field of Complexity Economics). It has been characterised as cybernetics where "circularity is taken seriously".

Heinz von Foerster (né von Förster; November 13, 1911 – October 2, 2002) was an Austrian-American scientist combining physics and philosophy, and widely attributed as the originator of second-order cybernetics. He was twice a Guggenheim fellow (1956–57 and 1963–64) and also was a fellow of the American Association for the Advancement of Science, 1980. He is well known for his 1960 Doomsday equation formula published in Science predicting future population growth.

As a polymath, he wrote nearly two hundred professional papers, gaining renown in fields ranging from computer science and artificial intelligence to epistemology, and researched high-speed electronics and electro-optics switching devices as a physicist, and in biophysics, the study of memory and knowledge. He worked on cognition based on neurophysiology, mathematics, and philosophy and was called "one of the most consequential thinkers in the history of cybernetics". He came to the United States, and stayed after meeting with Warren Sturgis McCulloch, where he received funding from The Pentagon to establish the Biological Computer Laboratory, which built the first parallel computer, the Numa-Rete. Working with William Ross Ashby, one of the original Ratio Club members, and together with Warren McCulloch, Norbert Wiener, John von Neumann and Lawrence J. Fogel, Heinz von Foerster was an architect of cybernetics and one of the members of the Macy conferences, eventually becoming editor of its early proceedings alongside Hans-Lukas Teuber and Margaret Mead.
