Les Ouvriers européens

Les Ouvriers européens (European Workers) is a six-volume study by French sociologist Frédéric Le Play, published in 1855. This work is significant for its development of the case-study method, where researchers lived with families to gather detailed data on their lives. Le Play's research focused on the family as a crucial element of social stability amidst the changes brought by industrialization. He opposed the idea of continuous societal evolution, instead proposing a theory of cyclical social changes linked to the morale of families. The study provided a detailed look at the conditions and lives of working-class families across Europe during a period of significant social and economic transformation.12
