Karl Bonhoeffer

Karl Bonhoeffer (; March 31, 1868 – December 4, 1948) was a German neurologist, psychiatrist and physician.
Life.
Bonhoeffer was born in Neresheim in the Kingdom of Württemberg to Friedrich von Bonhoeffer (1828–1907), who worked as judge in Ulm, and Julie Tafel (1842–1936). His brother was chemist Gustav-Otto Bonhoeffer. From 1887 to 1892 Bonhoeffer studied medicine at the University of Tübingen, in Berlin and in Munich. From 1904 to 1912 Bonhoeffer worked as a professor at the University of Breslau. From 1912 to 1938 Bonhoeffer worked at the Charité in Berlin. In 1898, he married Paula von Hase (1876–1951). Two of his children were Klaus Bonhoeffer and Dietrich Bonhoeffer, both of whom were executed by the Nazis. One of his daughters was Christine von Dohnanyi and one more son was chemist Karl-Friedrich Bonhoeffer. Bonhoeffer died in Berlin at the age of 80 after the end of World War II.
Bonhoeffer was a part of the resistance movement against the Nazis after 'Aktion T4' was started in 1939. He forged the documentation of disabled patients, suggested sources to other doctors to save patients and his two children died as a result from being a part of this cause. Although he contributed to the sterilization law, his efforts against 'Aktion T4' have made him remembered as a martyr for the lives that he saved and the influence he and his family had in fighting on the side of those who were deemed as 'useless eaters'.
