Karl Friedrich Bonhoeffer (born 13 January 1899 in Breslau; died 15 May 1957 in Göttingen) was a German chemist.


He was born as a son of Karl Bonhoeffer and Paula, together with seven brothers and sisters, most known are Klaus and Dietrich Bonhoeffer members of the German resistance.

In the year 1930 Bonhoeffer was appointed professor for physical chemistry at the University of Frankfurt. 1934 he was appointed as a professor for physical chemistry to the University of Leipzig. 1947 he became a professor for physical chemistry at the University of Berlin,

At the same time he was also director of the Kaiser Wilhelm Institute for physical and electrochemistry know the Fritz Haber Institute of the MPG.

In the year 1949 it was appointed as a director of the Max Planck Institute for Physical Chemistry in Goettingen.
