Born and raised in West Germany, after his Abitur Gerd-Rainer Horn emigrated to the United States where he then lived and worked for twenty-six years, along the way obtaining his B.A. (Minnesota), M.A. and Ph.D. (Michigan). He taught at Montana State and Western Oregon University before moving to the University of Huddersfield and then the University of Warwick in England. In 2013, Horn finally returned to Europe, now teaching at Sciences Po (Institut d'Études Politiques) in Paris. Focussing on the transnational dimension of continental western European social movements between the 1920s and the 1980s, Horn's particular areas of expertise include the political itinerary of social democracy, the socio-political challenges of the immediate post-WW II period, the cultural and political innovations of the 1960s and 1970s, in addition to the phenomenon of progressive Catholicism in Western Europe.

He has produced a highly scholarly work of singular importance, one that is credible, authoritative, and remarkably complete. It requires and deserves to be read carefully ... Horn is brilliant at capturing the overlap between the visions of a radical theology and the movements its proponents endorsed ... The best way of appraising this work is to treat it as the definitive benchmark for understanding the rise and fall of progressive Catholicism in the countries selected for study.
