Niklas Luhmann 1927 – 1998

Niklas Luhmann was a German sociologist and one of the leading systems theorists of the twentieth century. Trained as a lawyer and trained further in the United States under Talcott Parsons, he held a chair at Bielefeld for most of his career, where he produced an enormous theoretical corpus, the centerpiece of which is the two-volume Social Systems and the late synthesis Theory of Society. He treated modern society as a network of self-referential communicative systems including law, economy, politics, science, religion, and education, each of which constructs its own environment. His running debate with Habermas defined a generation of German social theory.

Niklas Luhmann was born in 1927 at Luneburg, the son of a brewer. Drafted into the Wehrmacht as a teenager at the end of the Second World War, briefly held as a prisoner of war, he studied law at Freiburg from 1946 and worked from 1953 in the public administration of Lower Saxony. A 1960 study year at Harvard with Talcott Parsons turned him decisively toward sociology, and in 1968 he was appointed to a chair at the new University of Bielefeld.

Over thirty years at Bielefeld he produced one of the most ambitious bodies of social-theoretical writing of the twentieth century: Trust and Power, the early Sociological Enlightenment essays, the great Social Systems (1984), the famous debate with Habermas Theory of Society or Social Technology?, and the long series of monographs on each of the major function systems — Law as a Social System, Art as a Social System, The Reality of the Mass Media, Religion of Society, Economy of Society — culminating in the posthumous Theory of Society (1997).

Luhmann developed a thoroughgoing systems theory that treats modern society as a network of communications structured into self-reproducing function systems, each operating with its own binary code; meaning, observation, and the difference between system and environment replace the older sociological vocabulary of action and structure. He died at Oerlinghausen near Bielefeld in November 1998.
