Ferdinand Tönnies, German sociologist and philosopher (b. 1855)
Ferdinand Tönnies (German: [ˈtœniːs]; 26 July 1855 – 9 April 1936) was a German sociologist, economist, and philosopher. He was a significant contributor to sociological theory and field studies, best known for distinguishing between two types of social groups, Gemeinschaft and Gesellschaft (community and society). He co-founded the German Society for Sociology together with Max Weber and Georg Simmel and many other founders. He was president of the society from 1909 to 1933, after which he was ousted for having criticized the Nazis. Tönnies was regarded as the first proper German sociologist and published over 900 works, contributing to many areas of sociology and philosophy. Tönnies, Max Weber, and Georg Simmel are considered the founding fathers of classical German sociology. Though there has been a resurgence of interest in Weber and Simmel, Tönnies has not drawn as much attention.
