Walter Wilhelm Oskar Hasemann (born June 26, 1890 in Gutach im Breisgau ; † September 28, 1961 in Freiburg im Breisgau ) was a German geologist and Baden state geologist.

He was the son of the painter Wilhelm Hasemann and Luise Lichtenberg. After graduating from secondary school in Freiburg, he studied geology at the Bergakademie Berlin from 1910 . From 1911 he continued his studies in Munich. However, it was interrupted by military service in the First World War from 1914 to 1918. During the war he married Maria Magdalena Reinhardt in Berlin in 1917, with whom he had two daughters. Before the war he had started his dissertation with August Rothpletz with a mapping in the Upper Bavarian mountains and completed the dissertation in 1919 under Ferdinand Broili , since Rothpletz had died in the meantime.

In 1920 he became a scientific assistant at the Baden Geological State Office in Freiburg. He was initially concerned with geological mapping: Completion of the Grießen map by Ferdinand Schalch , Eberbach , Zwingenberg , Malsch , Baden-Baden with his friend, the building officer and Professor A. Billharz, and Oberschefflenz . In 1926 he became a regional geologist. In addition, he wrote reports for the water supply and thermal springs ( Säckingen ). In 1938 he succeeded Carl Schnarrenberger as director of the Baden Geological State Office. In 1940 it became a branch of the Reich Office for Soil Research and Hasemann was head of the district geologist and in 1942 it became a government geologist. In 1939/40 he was drafted as a military geologist . Besides water drilling, the main activity was oil drilling in the southern Upper Rhine Rift. In November 1944 he was drafted into the Volkssturm and was taken prisoner by the French and then by the United States, and was released in January 1946.

After the war, he was involved in the reconstruction of the destroyed state office, continued to advise on oil drilling and led new exploration wells for the Buggingen potash salt mine . After his retirement he was a permanent employee of the Geological State Office of Baden-Württemberg. He dealt with the geology of the Wutach Gorge and the Tertiary and Mesozoic Era around the Kaiserstuhl (supported by his daughter Waltraud, a micropalaeontologist). In 1959 his explanations for the geological excursion map of the Kaiserstuhl appeared.

He was an honorary member of the Upper Rhine Geological Association and the Baden State Association for Natural History and Nature Conservation.
