Karl Brandt and his wife Anni were as the Albert Speer and his wife members of Hitler's inner circle in Berchtesgaden, where Hitler maintained his private residence known as the Berghof. This highly exclusive group functioned as Hitler's de facto family circle.

As members of this inner circle, the Brandts had a residence near the Berghof and spent a lot of time there when Hitler was present.

There was real competition for the leader's affection around this Berghof residence, everyone wanted to be close to him to expand his power or simply to gain advantages - to build a villa, to go on vacation.

Brandt was a careerist who was involved in serious crimes such as the Aktion T4 euthanasia program. - 1939
