Karl-Heinz Roth is a doctor, historian, publisher and former activist for German workers' autonomy. In his political parable is contained the curve of the best radical vanguards of Germany. His trajectory is inscribed in the struggle against the consensus that before 1968 was imposed as the pretended conquest of an inescapable progress and later suffocating repressive operation of the revolutionary experience of the new social movements. His intense militant work has been combined with an energetic research activity in the field of history and mutations of the capitalist world system. Tracantes de Sueños will also soon publish his book: El? Otro? labor movement.
