Joachim Sauer is a quantum- and physio-chemist. He is a professor of physical and theoretical chemistry at the Humboldt University of Berlin. He is also the husband of Germany’s chancellor, Angela Merkel.
The election of his wife to the most powerful governmental position in all of Germany had no impact on his career. They seldom appear together in public. He declines to answer any interview questions that do not have to do with his own research. In federal elections his part is irrelevant.
Public life is clearly separated from private life. The home-life scene is irrelevant in determining political success. This same pattern can also be seen in the careers of Joschka Fischer (former German Foreign Minister) and Gerhard Schröder (Merkel’s predecessor as Chancellor). Both were married several times.
