Jacob Hildenbrand

Jacob Hildenbrand , also Jakob Hildenbrand (born December 14, 1826 in Dürnau , Donaukreis , † April 28, 1904 in Ohmenhausen ) was a German geologist who worked on the first geological mapping of Württemberg.

Hildenbrand was originally a weaver. He was suggested by Friedrich August Quenstedt for participation in the state registration, which initially met with resistance in Stuttgart. The head of the mission Heinrich Bach trained him with Quenstedt and by 1883 he created a total of 25 sheets of the atlas (geological maps 1: 50,000) independently edited (including Göppingen , Schwäbisch Gmünd ), another 11 with others. That was the area of half of the Kingdom of Württemberg. He was officially only an auxiliary geologist (auxiliary geognost).

The geognostic atlas of Württemberg appeared until 1892. Besides Bach, Quenstedt and Hildenbrand, the main collaborators were Karl Deffner , Oscar Fraas and Karl Eduard Paulus .

In mapping, he invented the needle prick method, in which entries were made on the back and linked to the front by needle pricks.

In 1876 he received the small gold medal for art and science from the Kingdom of Württemberg.

He also managed the shale oil factory founded by Quenstedt near Reutlingen , where oil was extracted from the Posidonia slate of the Lias . It was Hildenbrand who found a famous sea lily plate there.
