from Wikipedia, the free encyclopedia

Friedrich Hartmann (also: Georg Friedrich Hartmann and Johann Georg Friedrich Hartmann ; * July 4, 1796 in Elbingerode ; † August 23, 1834 in Hanover ) was a German university professor , mathematician , captain, military scientist and geodesist .

Life

Friedrich Hartmann was born during the personal union between Great Britain and Hanover at the time of the Electorate of Hanover . After the so-called " French era " and the establishment of the Kingdom of Hanover , he first learned to work as a Bergeleve from 1814 , before joining the artillery regiment in Hanover in 1816. He was appointed captain in 1817 and taught from 1821 as a teacher of practical geometry together with Georg Wilhelm Müller at the Royal Hanover Artillery School and the General Staff Academy there . From 1823 to 1833 he worked under Carl Friedrich Gauß on the Hanoverian degree and state surveying: The " Hanoverian regional triangulation " was headed by Gauß, who also carried out the calculations, while the officers Joseph Gauß , Georg Wilhelm Müller and Friedrich Hartmann carried out the local work. In the years 1830 and 1831 Hartmann observed the triangular network in the west of Oldenburg.

During a meeting of the Astronomical Society in London on June 11, 1830, a letter from Hartmann to JTW Herschel was reported with the "description of an instrument that the optician Hohnbaum in Hanover made for him according to his instructions."

In 1831 Hartmann retired as a captain from active military service in the army of the Kingdom of Hanover and began teaching practical geometry and geometric drawing at the “Höhere Gewerbeschule” , which opened in the same year - as a polytechnic school from 1847.
