Franz Jakob Goebel

from Wikipedia, the free encyclopedia

Franz Jakob Goebel (born July 16, 1791 in Mingolsheim , Grand Duchy of Baden , † August 23, 1858 in Baden-Baden ) was a German mathematician and professor at the University of Leuven .

Life

Franz Jakob Goebel was the second of five children of Johannes Franciscus Xaver Goebel (in second marriage) with Maria Theresia geb. Eisel . As early as the age of seven, his father died in 1801 and his mother, he was by the age of 10 orphan . The local pastor at the time, Franz Xaver Bender, promoted his special skills and made it possible for him to attend the Lyceum in Baden-Baden at the age of 15 . In 1813 he matriculated to study philology at the University of Heidelberg . He also studied mathematics and had to finance his studies with private lessons due to financial difficulties.

In December 1813 he joined the army of the Grand Duchy of Baden to take part in the liberation struggle against Napoleon Bonaparte . After the battle was over, he left the military in 1814 and continued his studies in Heidelberg. On September 4, 1817 he received his doctorate at the Philosophical Faculty. He had insisted on being able to do a doctorate immediately because he had received a teaching offer at the newly founded Reich University of Leuven . During his exams it was noticed that he had limited mathematical knowledge. The philosopher Georg Wilhelm Friedrich Hegel , who was one of the examiners, was surprised that someone with such limited mathematical knowledge was appointed professor of mathematics and resisted Goebel's appeal after Goebel had again submitted a dissertation .

When the Reich University of Leuven was founded, Goebel was actually appointed full professor at the Faculty of Mathematics and Physics in 1817. He taught elementary mathematics, the principles of arithmetic and algebra, geometry, analytical geometry, flat and spherical triangulation, advanced mathematics (differential and integral calculus) and astronomy. In 1820 he set up a mathematics seminar for students preparing for their educational careers. In this seminar he dealt with both pure and applied mathematics. After a few years Goebel was delighted to see that his students were appointed teachers at almost all high schools in the southern Netherlands.

Goebel was rector magnificus of the university in the academic year 1823/24 .

In August 1830 there was a revolution in Belgium against unification with the Netherlands, he and Franz Joseph Dumbeck and Franz Josef Mone lost their jobs at the university and had to leave the country. Goebel returned to Baden, but kept half of his salary at the expense of the Dutch state. He remained active as an author of textbooks.

On November 25, 1833, he married in Baden-Baden as a widower Marie Adelheid von Harrant (1803-1875). Five years later, in 1838, his name was changed to "Goebel von Harrant" through ennoblement . His son Edmund August Valentin Jacob Luois (* 1836; later captain and major around 1871) was also allowed to bear this name. After his death, his widow kept half of the Dutch discharge allowance.

Goebel became an honorary citizen of Baden-Baden on August 26, 1843 .
