Abstract
Ralf Dahrendorf (1929-2009) established modern sociology as a normal science in the traditional university in post-war Germany. After ten years as a Full Professor, he joins the German liberal party, then in opposition. He stands successfully in a regional and then a national election (Landtag, Bundestag). He serves as junior minister under chancellor Willy Brandt and becomes a European commissioner less than a year later. Upon his resignation from the European Commission, he makes the UK his home and becomes a British subject, becomes knighted and later appointed Lord. The second half of his life, as an intellectual amid the powers and a liaison between England and the continent, as a self-described 'straddler', may have been even greater in importance than the first, with his meteoric rise as a highly visible professor of sociology and as German politician of national prominence. His analysis of society and democracy in Germany, though dated (1965) appears still for the most part as valid. Historically, his own elite positions mark transition periods in the process of generational change.
