Bonhoeffer family

He became a prominent psychiatric consultant on culpability and insanity defense, who, after the Reichstag fire of 1933 attested Marinus van der Lubbe's capacity for guilt in the Leipzig Trial.

As a follower of Emil Kraepelin, he worked on differential diagnosis to delimit schizophrenia and paranoia from a delirium as organic brain syndrome.

His successor at the Charité Hospital, Max de Crinis, was deeply involved in the Nazi abuse and murders of the Action T4 "euthanasia" programme.

Dietrich, as a Protestant theologian became a member of the Confessing Church, joined the German resistance to fight against the evils of Nazi Germany, was arrested in 1943, and executed on April 9, 1945, at Flossenbürg concentration camp, with his brother-in-law Hans von Dohnányi.

Klaus Bonhoeffer and his brother-in-law Rüdiger Schleicher likewise joined the resistance, were arrested, and, with other conspirators of the 20 July plot, found guilty by the "People's Court" (Volksgerichtshof) under presiding judge Roland Freisler on October 2, 1944; they were shot by Gestapo henchmen in the night of April 22–23, 1945, near the ruins of Berlin Lehrter Bahnhof, while Red Army forces entered the city.
