“Zein,” as friends and colleagues knew him, practiced an interpretive anthropology that, like the writing of history, is a craft in which the best work is realized only after long years of field experience, study, and the development of concepts and themes through teaching and writing. Zein's sudden death on 13 August 1979 at the age of 44 cut short his work just as it began to achieve its fullest form.
Zein's professional career was divided between two remarkably distinct periods. The first of these lasted for roughly the decade prior to 1966, during which he mastered the conventions of what might be called a standard, functionalist anthropology and applied them to ethnographic research in Egypt. The second period began in 1966 with his participation in the formative period of symbolic anthropology at the University of Chicago.
