Shmuel Eisenstadt was a sociologist. He studied with Martin Buber and obtained his PhD at Hebrew University in Jerusalem. He remained there as a dean and professor until his death in 2010, while frequently acting as visiting professor and receiving many honorary doctorates elsewhere. Eisenstadt developed the theory of ‘multiple modernities’ and placed social developments in a broad, interdisciplinary framework. His major works are Modernization, Protest, and Change (1966), Patterns of Modernity (1987) and Fundamentalism, Sectarianism and Revolutions (1999).
