Karl–Hermann Geib (March 12, 1908 – July 21, 1949) was a German physical chemist who, in 1943, developed the "dual temperature exchange sulphide process" (known as the Girdler sulfide process) which is regarded as the "most cost-effective process for producing heavy water". A parallel development of this process was achieved by Jerome S. Spevack at Columbia University and became the basis of post-World War II production of heavy water in the United States at the only remaining facilities located at Wabash River Ordnance Works, near Dana and Newport, Indiana, and the Savannah River Site.
Geib was born in Berlin, Germany, on March 12, 1908 to Karl Geib and his wife Maria (née Buddee). He married Hedwig Delbrück and they had four children, Katharina Oestreich, born 1937, Barbara Pietsch, born 1938, Ruprecht, born 1939 and Ulrike Heise, born 1940.
In 1931, he graduated from Leipzig University and joined the Institute of Physical Chemistry and Electrochemistry of Kaiser Wilhelm Society, which is known today as the Fritz Haber Institute of the Max Planck Society.
In 1931, while under the supervision of Paul Harteck, in Berlin, Geib delivered his dissertation on The Action of Atomic to Molecular Hydrogen and joined the Kaiser-Wilhelm Institut für physikalische Chemie und Elektrochemie of the Kaiser-Wilhelm Gesellschaft in Berlin-Dahlem. The first scientific work he performed under the direction of Paul Harteck. Shortly after Hartek highway crossing in Cambridge Geib returned to alma mater – the Leipzig University and married Hedwig Delbrück.
