Marvin Harris was an influential American anthropologist known for his work in cultural materialism. Born on August 18, 1927, he focused on how material conditions, such as environment and economy, shape cultural practices and beliefs. His notable books include Cows, Pigs, Wars, and Witches and Our Kind, which explore the relationship between culture and human behavior. Harris's theories challenged traditional anthropological views that emphasized ideas and symbols over material factors. He argued that understanding human societies requires examining their economic and ecological contexts. His contributions have significantly impacted the fields of anthropology and sociology, making him a key figure in the study of culture.
