Wilhelm Geilmann

from Wikipedia, the free encyclopedia

Wilhelm Ludwig August Geilmann (born May 16, 1891 in Unterrieden (Witzenhausen) , † May 24, 1967 in Mainz ) was a German chemist who dealt with analytical chemistry and was a professor at Johannes Gutenberg University in Mainz .

life and work

Geilmann studied chemistry at the University of Göttingen from 1911 and received his doctorate there in 1914 under Carl Mannich on the detection of methyl alcohol. After military service in World War I, he was an assistant at the Agricultural Chemistry Institute at the University of Göttingen. From 1923 he worked with Wilhelm Biltz at the Technical University of Hanover, completed his habilitation there in 1924 and in 1928 received a teaching position for mineral analysis and soil science, later for special analytical and inorganic chemistry. In 1929 he became an associate professor and in 1939 an adjunct professor. In 1944 he took over the newly created department for special analytical chemistry. In 1950 he became associate professor for analytical chemistry at the University of Mainz.

Initially he dealt with agricultural chemistry and soil analysis (including nitrogen microanalysis and the influence of various substances on the growth of plants). He carried out chemical investigations of archaeological finds (such as weapons from the Bronze Age, metallic mirrors from Roman times and medieval wall paintings) as well as methods of their conservation, dealt with the chemistry of rhenium (which he thoroughly researched in a series of publications) and microchemicals Analyzes (including dimensional analysis, flame analysis). He also dealt with selenium ore deposits, uptake of germanium in plants, glass analysis. After Bode and Strassmann were honored on their 60th birthday, he was a leading analyst in Germany who mastered both modern and ancient methods of investigation (and was one of the last masters of analysis on the dry path).

In 1942 he became a member of the Leopoldina . In 1962 he was the first to receive the Fresenius Prize .
