Dorothea and Wolfgang Koch write regularly for Catholic magazines in Germany. They are particularly interested in the idea of Christian democracy and the devotion to Our Lady that has shaped post-war Western Germany in the Adenauer Era. Their book Konrad Adenauer: The Catholic and His Europe is popular among German Catholics. Wolfgang Koch, a physicist, is Chief Scientist at one of the Fraunhofer Institutes and a professor of computer science at the University of Bonn. Their five children are now grown up, and Dorothea Koch, a chemist, works to spread knowledge about Konrad Adenauer from his home in Rhöndorf, a German National Historical Site.
