Monument to Hans Hauenschild in Windischgarsten

Hans Hauenschild (born August 14, 1842 in Windischgarsten ( Upper Austria ), † June 26, 1901 in Vouvry ) was an Austrian researcher , inventor and owner of numerous patents in the field of cement production .

Life

Hans Hauenschild was the son of the dying couple Johann and Elisabeth Hauenschild. His father died when he was four years old. The mother was left impoverished with two children. Hauenschild attended elementary school in Windischgarsten, where a street is named after him. His teacher, Mayor Leopold Westermayr, recognized his talent and made it possible for him to attend the Stiftsgymnasium Kremsmünster . It was there that Hauenschild's interest in the natural sciences was awakened. In 1861 his mother died. In 1863 he graduated from high school as the best in his class and entered the Benedictine Abbey of Kremsmünster as a novice under the name Gottfried . From 1864 to 1868 he studied theology at St. Florian Monastery . After his ordination in 1868, Hauenschild studied natural history, physics and mathematics in Vienna. During the holidays he conducted scientific studies in the mountains surrounding his home town of Windischgarsten until 1871. He published his findings in the yearbooks of the Austrian Alpine Club . It was through him that the chalk gap in Hinterstoder was first researched.

In 1871 his son Albrecht was born. He therefore decided in spring 1872 to leave the Benedictine order and, together with his bride, Maria Wittmann, to convert to the evangelical confession and to marry. This section of his life is described in Max Burckhard's novel "Gottfried Wunderlich" (1906). He had 12 children with Maria Wittmann.

The new building material cement brought him in connection with a completely new science, geology. His inventions, especially the method of continuously burning Portland cement in shaft furnaces , revolutionized the cement industry. Hauenschild was so well known that he was consulted on geological and structural issues during the construction of the Vienna high spring water pipeline and the Gotthard Railway in Switzerland.
