The differences between Wilma and Georg Iggers’ view of life become clear in the double biography ‘Zwei Seiten der Geschichte’, among others. due to the different experiences in childhood and adolescence. However, they also complement each other in a certain sense. The question of justice and the values that are necessary for building a humane society have played and still play a major role for both. However, the belief in moral progress that arose in youth has grown to a certain skepticism in the face of a world determined by fear and aggression. Despite this pessimism, Wilma and Georg Iggers are convinced of the need to work to improve the situation of the people.
