Life

Christian August Vogler, son of a Wiesbaden doctor, switched to a military school in 1856 after attending primary school and grammar school in Wiesbaden, where he was taught topography, plan drawing, surveying and instrumentation in addition to the usual school subjects . After taking the first and second officer exams, he worked as a teacher at the military school for three years. He then went to the Polytechnic School in Munich to study engineering .

In 1868, Karl Maximilian von Bauernfeind appointed him as an assistant to the Bavarian Degree Measurement Commission in Munich to carry out precision leveling . At the same time he attended lectures in mathematics, physics and astronomy at the Polytechnic School and the Ludwig Maximilians University in Munich. In 1873 he was awarded a doctorate degree from the Ludwig Maximilians University under Gustav A. Bauer with a dissertation on the subject: About goals and tools of geometric precision leveling , in which the geometric leveling was presented scientifically for the first time. phil. PhD. In 1874 he was appointed as a private lecturer at the Polytechnic School in Aachen through the mediation of Friedrich Robert Helmert .

In 1880 he moved to the Agricultural Academy in Bonn-Poppelsdorf as a full teacher of surveying. With the inaugural lecture The Geodetic Tasks of Degree Measurement , he completed his habilitation in the winter semester 1880/81 at the philosophical faculty of the Rheinische Friedrich-Wilhelms-Universität Bonn , which appointed him extraordinary professor in 1882. On April 1, 1883, he was appointed full professor of geodesy at the newly created geodetic institute of the Agricultural University in Berlin. In Vogler's request of February 1883 to be able to “ hold lectures on geodesy ” at the Berlin University , the philosophical faculty believed “ at first not to recognize an urgent need ”. In 1893 he suggested a call to the chair of geodesy at the Technical University of Dresden as the successor to August Nagel . In 1896 he was elected a member of the German Academy of Sciences Leopoldina . From 1900 to 1902 he was rector of the Agricultural University in Berlin. In 1921 he was retired after reaching the age of eighty.

His standard work was fundamental : Basic Teachings of Cultural Techniques , which appeared for the first time in 1896 and was subject to further editions. He constructed a precision leveling instrument in which the telescope could be raised or lowered vertically to within a hundredth of a millimeter by means of a height adjustment, a glass scale attached to the instrument and a scale microscope. For precision leveling , he replaced the unsuitable wooden slats with steel slats fitted with metal thermometers. With measuring instruments and personal advice, he supported the archaeological investigations, measurements and excavations on the island of Thera . At his suggestion, the Gauss small calculating machine was developed by the Mercedes company in 1905.

Christian August Vogler was the undivided admiration of his students. In 1903 he was made an honorary member of the Saxonia ad chain, the later RSC Corps Saxonia-Berlin.
