John D. Early is Professor Emeritus of Anthropology at Florida Atlantic University. Dr. Early joined the faculty of the Anthropology Department in 1969. He was chair of the department for several years and retired in 1993. His educational background includes a Bachelor of Arts in Philosophy and Master of Arts in Social Philosophy from St. Louis University, a Master of Arts in Theology from Woodstock College (a Jesuit Seminary), a Master of Arts in Sociology from Fordham University, and a PhD in Anthropology-Sociology from Harvard University (1965). Dr. Early began his career as a Jesuit priest, although he resigned from the priesthood in 1969. As a member of the Harvard-Chiapas Research Project, he went to Zinacantán to study Maya worldview and its Catholic elements. Later, his interest turned to demographic research as a planning basis for the literacy, cooperative and health programs in which he was involved among the Maya in Guatemala. It was also intended to bring to national and international attention to the severe malnutrition and high mortality among the Maya primarily as a result of social injustice. This interest then turned into fulltime research on the evolution of human population dynamics: for hunter-gathering groups as exemplified by the Agta in the Philippines, for tribal groups as exemplified by the Yanomami in Brazil, for peasants by the Maya in Mexico and Guatemala.
