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

As the son of Karl and Paula Bonhoeffer von Hase Karl Friedrich Bonhoeffer grew up in a family of educated middle class, along with seven siblings, including his brothers Klaus and Dietrich Bonhoeffer. With his wife Grete von Dohnanyi, sister of Hans von Dohnanyi, he had four children. Another brother was Max Delbrück.

Bonhoeffer studied from 1918 in Tübingen and Berlin. In 1922 he received his doctorate in Berlin with Walther Nernst. From 1923 to 1930 he was an assistant with Fritz Haber at the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry at Berlin- Dahlem. After his habilitation in 1927, he was associate professor at the University of Berlin.

In 1930, Bonhoeffer became a full professor of physical chemistry at the University of Frankfurt. In 1934 he was appointed Professor of Physical Chemistry at the University of Leipzig. In 1938 he was elected a member of the Scholars Academy Leopoldina.

In 1947 he became professor of physical chemistry at the University of Berlin, who is also director of the Institute for Physical Chemistry and Electrochemistry of the Kaiser Wilhelm Society for the Advancement of Sciences in Berlin -Dahlem (now the Fritz Haber Institute of the Max Planck Society). In 1949 he was appointed director of the Institute of Physical Chemistry of the Max Planck Society to Göttingen.

The latter emerged in 1971 from the Max Planck Institute for Biophysical Chemistry in Göttingen bears the honorary name of " Karl -Friedrich Bonhoeffer Institute ".

In 1929 he discovered along with Paul Harteck the hydrogen modifications ortho-and para-hydrogen and came with the publication of Arnold Eucken few days earlier.

The science historian Ute Deichmann sees Bonhoeffer, who was a member of the NSDAP never and some " half-Jewish " scientists has given job opportunities in his institute, the example of a scientist who, although against the National Socialism is critically set to protest adapts to the prevailing conditions ( " with the wolves you have to howl ").

Named after Karl Friedrich Bonhoeffer Max Planck Institute for Biophysical Chemistry situated on several pages his resume dar. This also includes a portion that is which deals with the resistance of the Bonhoeffer family during the Nazi era.
