Manuel Gamio (1883–1960) was a Mexican anthropologist, archaeologist, sociologist, and a leader of the indigenismo movement. Although he rejected full sovereignty for indigenous communities in Mexico, he argued that their self-governing organizations, such as tribal governments, municipal organizations, and elected community leaders should be recognized and respected. He is often considered as the father of modern anthropological studies in Mexico. He devised a well-known system for classifying the hunter-gatherers of Central America.
Gamio was born in Mexico City, where he studied engineering at the School of Mining. However, at age 19 he left his studies to work on a family rubber plantation, where the states of Oaxaca, Veracruz and Puebla join. There he learned Nahuatl from the plantation workers and developed a strong interest in Mexico's indigenous cultures.
He returned to study at the National Museum under Zélia Nuttall, who in 1909 sent him to study under Franz Boas at Columbia University. There he earned a Ph.D. From Boas he adopted the cultural approach characteristic of the anthropology of the United States in the twentieth century. Boas considered Gamio one of his best students.
He returned to Mexico in 1910 and the following year he was among the founders of the Escuela Internacional de Arqueología y Etnología Americana (International School of Archaeology and Ethnology of the Americas) in Mexico City, with funds obtained from Germany and the United States. Other individuals associated with the school included Eduard Seler, Alfred M. Tozzer and Boas. This was during the Mexican Revolution, and thus was a difficult time to establish new scientific institutions. Gamio was director of the school from 1916 through 1920, when it closed for lack of funds.
