Bruno Latour (born June 1947, Beaune, France) is a French sociologist of science best known for his books We Have Never Been Modern, Laboratory Life, and Science in Action. Although his studies of scientific practice were at one time associated with social constructionist approaches to the sociology of science, Latour has diverged significantly from such approaches. Along with Michel Callon and John Law, Latour is one of the primary developers of actor-network theory (ANT), a constructionist approach influenced by the ethnomethodology of Harold Garfinkel, the generative semiotics of Algirdas Julius Greimas, and the maverick sociology of Durkheim's rival Gabriel Tarde.
