Life

Adolf Georg Oscar Kleinlogel was born in December 1877 as the son of the factory director Oskar Kleinlogel and his wife Marie Schönleber in Wildbad. After graduating from high school, Kleinlogel worked for a year in a machine factory in Geislingen. He then began studying mechanical engineering at the TH Stuttgart . During his studies he became a member of the Alemannia Stuttgart fraternity . After the state examination and military service, he dealt with reinforced concrete and became Carl von Bach's assistant at the materials testing institute in Stuttgart. With his research together with Emil Mörsch and Otto Graf of reinforced concrete for bending, compression and tension, he carried out theoretical and practical pioneering work.

Kleinlogel followed Mörsch in 1904 to Wayss & Freytag AG in Neustadt an der Haardt , where he rose to senior engineer.

In 1910 he received his doctorate at the TH Dresden on the subject of "About the nature and the true size of the bond between iron and concrete" and completed his habilitation in 1912 at the TH Darmstadt with a thesis "About recent experiments with constricted concrete". This went hand in hand with the position of private lecturer at the TH Darmstadt. He also settled in Darmstadt and founded an engineering office.

During the First World War he was an officer and built the first reinforced concrete shelters.

From 1922 to 1943 he headed the magazine Eisen und Beton , in which he followed his friend Friedrich Ignaz von Emperger . He also founded and directed the building protection magazine until 1942.

He traveled to Europe, the Soviet Union, and North and South America by traveling as an appraiser and expert. From the USA he transferred experience in concrete road construction to Germany.

His collection of formulas, frame formulas , has had 17 editions since 1914 (1993).

In 1919 Kleinlogel was awarded the title of professor. In 1925 he was appointed an adjunct professor. In particular, he held lectures on the applications of concrete construction. He held this position until 1935. In the autumn of 1936 Kleinlogel was dismissed for political reasons because he had employed a foreign citizen of Jewish faith in his engineering office. Kleinlogel had been violently attacked by an article in Stürmer in April 1936 with the title “The Professor and his House Jew”.

From 1947 he worked again as an adjunct professor at the TH Darmstadt.

His uncle is the painter Gustav Schönleber .

Kleinlogel died in Darmstadt at the age of 80. He was married to Else Henninger since 1905.
