20th-century anthropologists

Helmuth Plessner (4 September 1892, Wiesbaden – 12 June 1985, Göttingen) was a German philosopher and sociologist, and a primary advocate of "philosophical anthropology".

Henri Victor Vallois (11 April 1889 – 27 August 1981) was a French anthropologist and paleontologist. He was one of the editors in chief of the Revue d'Anthropologie from 1932 to 1970, and became director of the Musée de l'Homme in 1950.

Alfred Métraux (5 November 1902 – 12 April 1963) was a Swiss and Argentine anthropologist, ethnologist and human rights leader.

Lydia Cabrera (May 20, 1899, in Havana, Cuba – September 19, 1991, in Miami, Florida) was a Cuban independent ethnographer, writer, and literary activist. She was an authority on Santería and other Afro-Cuban religions. During her lifetime she published over one hundred books; little of her work is available in English. Her most important book is El Monte (Spanish: "The Wilderness"), which was the first major ethnographic study of Afro-Cuban traditions, herbalism and religion. First published in 1954, the book became a "textbook" for those who practice Lukumi (orisha religion originating from the Yoruba and neighboring ethnic groups) and Palo Monte (a central African faith) both religions reaching the Caribbean through enslaved Africans. Her papers and research materials were donated to the Cuban Heritage Collection - the largest repository of materials on or about Cuba located outside of Cuba - forming part of the library of the University of Miami. A section in Guillermo Cabrera Infante's book Tres Tigres Tristes is written under Lydia Cabrera's name, in a comical rendition of her literary voice. She was one of the first writers to recognize and sensitively publish on the richness of Afro-Cuban culture and religion. She made valuable contributions in the areas of literature, anthropology, art, ethnomusicology, and ethnology.
In El Monte, Cabrera fully described the major Afro-Cuban religions: Regla de Ocha (commonly known as Santeria) and Ifá, which are both derived from traditional Yoruba religion; and Palo Monte, which originated in Central Africa.
Both the literary and anthropological perspectives in Cabrera's work assume that she wrote about mainly oral, practical religions with only an “embryonic” written tradition. She is credited by literary critics for having transformed Afro-Cuban oral narratives into literature, which is, written works of art, while anthropologists rely on her accounts of oral information collected during interviews with santeros, babalawos, and paleros, and on her descriptions of religious ceremonies.
There is a dialectical relationship between Afro-Cuban religious writing and Cabrera's work; she used a religious writing tradition that has now internalized her own ethnography.

Gonzalo Aguirre Beltrán (January 20, 1908 in Tlacotalpan, Veracruz –1996 in Xalapa, Veracruz) was a Mexican anthropologist known for his studies of marginal populations. His work has focused on Afro-Mexican and indigenous populations. He was the director of the National Indigenous Institute and as Assistant Secretary for Popular Culture and Continuing Education he was responsible for forming government policy towards indigenous populations. For this reason he is important in the field of applied anthropology.

Pierre-Roland Giot (September 23, 1919 – January 4, 2002) was a French anthropologist, archaeologist and geologist.

Claude Meillassoux (; French: [mɛjasu]; December 26, 1925 – January 3, 2005) was a French neo-Marxist economic anthropologist and Africanist. A student of Georges Balandier, he did fieldwork among the Guro (Gouro) of Côte d'Ivoire; his thesis was published in 1964. In the 1970s he criticised Marshall Sahlins's use of the notion of "domestic mode of production". Meillassoux was throughout his life a politically committed critic of social injustice.

Ruth Vilaça Correia Leite Cardoso GCIH (19 September 1930 – 24 June 2008) was a Brazilian anthropologist and a member of the faculty of philosophy, letters and human sciences at the University of São Paulo (FFLCH-USP). She was the wife of 34th president of Brazil, Fernando Henrique Cardoso, and First Lady of her country between 1 January 1995 to 31 December 2002. She too was a Ph.D. in anthropology from the University of São Paulo.
As professor and researcher Cardoso taught at the Latin American College of Social Sciences (Flacso/Unesco), University of Chile (Santiago), Maison des Sciences de L'Homme (Paris), University of California, Berkeley, and Columbia University (New York City). She was an associate member of the Center for Latin American Studies of the University of Cambridge. With her husband, the sociologist and former president of Brazil, Fernando Henrique Cardoso, she founded and later directed the research institute Cebrap (Centro Brasileiro de Análise e Planejamento – Brazilian Center of Analysis and Planning), which continues to be a leading site of social science research in Brazil.Dr. Cardoso's academic reputation rests primarily on a series of highly influential articles and book chapters on popular movements and political participation that she published in the 1980s and 1990s. Under Dr. Cardoso, Cebrap created Brazil's first research group on social movements, helping to legitimate formal academic study of the "new" (non-class) social movements that had emerged in the 1970s. At the same time, she was careful to stress the limits of identity-based and popular movements for political transformation, noting the divisions among them and their frequent dependency on clientelistic relations with the state and political parties.
Unlike many academics, Dr. Cardoso also had the opportunity to put some of her theories into practice after her husband was elected president. She transformed the traditional charity approach of other first ladies with her Comunidade Solidária (Solidary Community) programs that stressed the role of non-governmental organizations (NGOs) in state-society partnerships. In addition to executing concrete social programs, Comunidade Solidária also facilitated broad discussions of important social topics, from agrarian reform to the legal status of NGOs, publishing the results of these dialogues. Anthony Hall of the London School of Economics told the BBC after her death that she was instrumental in developing the plan to bundle various social programs together in the way that has become characteristic of the successful Bolsa Familia social program. She published a book about these experiences, Comunidade Solidaria: Fortalecendo a Sociedade, Promovendo O Desenvolvimento (Comunitas, 2002). She transformed the Comunidade Solidaria into an NGO, Comunitas, after her husband left office.

She died in São Paulo on 24 June 2008, after suffering a cardiac arrest. She had been discharged from the Sírio-Libanês Hospital the previous day, 23 June 2008, having previously been admitted with chest pains.
