Johannes Ahlburg

from Wikipedia, the free encyclopedia

Johannes Heinrich Wilhelm Ahlburg (born September 9, 1883 in Treuenbrietzen , † September 22, 1919 ) was a German geologist.

Life

The son of a teacher lived in Hamburg from 1892 , where he attended the Johanneum and graduated from high school in 1902. He then did a practical training in mining ( Lautenthal , Kalisalzbergwerke Vienenburg and Barsinghausen ) and studied from 1903 at the Bergakademie and the University in Berlin, among others with Wilhelm von Branca . In 1906 he received his doctorate on palaeontology and stratigraphy of the Triassic in southern Upper Silesia and was then assistant to Robert Scheibe at the Bergakademie, where he passed the exam as a mining trainee in 1906 (with a thesis on the Minette deposit in Lorraine ). In 1906 he joined the Prussian Geological State Institute (PGLA) as a test geologist and mapped (initially with Heinrich Lotz (1873-1943)) in the Devonian the Lahnmulde and its iron ore deposits. Ahlburg also did a lot of work abroad, in Russia, Hungary and what was then the Netherlands in Indonesia, in particular researching the geology of Celebes . Most recently he was a royal geologist.

With Wilhelm Kegel he was a pioneer in researching the geology of the Lahn-Dill area (Lahnmulde, Gießener blanket ).

In the First World War he was initially a soldier at the front, but then took care of the development of phosphorite and manganese ore stores in the Lahn area. He died in 1919 of the then rampant Spanish flu .
