Escuela de Fráncfort
The Frankfurt School is a school of neo-Marxist social theory, social research and philosophy. The grouping emerged at the Institute for Social Research ("Institut für Sozialforschung") of the University of Frankfurt am Main in Germany. The term "Frankfurt School" is an informal term used to designate the thinkers affiliated with the Institute for Social Research or influenced by them—it is not the title of any institution and the main thinkers of the Frankfurt School did not use the term to refer to themselves.
