Karl Reinhard Müller
Karl Reinhard Müller , occasionally also Carl Reinhard Müller , nickname Reinhard (born April 17, 1774 in Steinau near Hanau ; † March 12, 1861 in Marburg ) was a German mathematician , music theorist and honorary citizen of the city of Marburg .
family
Karl Reinhard Müller was born as the son of a citizen and "model clerk" (that is, battalion or regiment clerk) and a daughter of the "city captain" and "councilor relative" of Steinau an der Strasse named Euler. He had been married to Christiane, nee Greif, since 1802, who bore him seven children, three of whom died early, including his only son. One daughter was married to the lawyer and sociologist Karl Friedrich Vollgraff .
education and profession
Müller attended the city school in Steinau and also received private lessons in Latin, Greek and music. From 1788 until 1792 he attended high school in Hanau ; He financed his school attendance - coming from a poor family - through membership in the Hanau Singing Choir and through privately given piano lessons. After attending individual lectures at the Hanau illustri superiore high school, which existed at the time, he switched to the University of Marburg in 1794 .
In 1795 Müller took up a position as private tutor, which he used to finance his further studies. In addition to his two main areas of interest, mathematics and music, he also increasingly dealt with “school science”. In 1800 he became the fourth teacher at the Marburg Pedagogy , the university's preparatory school, and in 1803 he became the second teacher there. He taught almost all high school subjects, including the ancient languages, as well as history, geography and physics, but mainly mathematics, which at that time was not yet part of the canon of subjects, and in addition to his actual obligations, he took over the teaching of singing free of charge.
On April 17, 1809 he received his doctorate from the University of Marburg as a doctor philosophiae ; at the same time the habilitation was completed. His dissertation dealt with the extraction of the cube root from binomies ; he published them in the school program of the pedagogy and later published them in a greatly expanded version (→ writings ).
On June 2, 1815, he was appointed associate professor of mathematics with no salary at the University of Marburg; only in 1834, after he had given up his teaching post at the pedagogy, did he receive an annual gratuity, and only in 1838 was he granted a regular salary. The various efforts of the university to get him a full professorship were unsuccessful.
He re-edited Christian Wolff's Introduction to Mathematics, read about pure and applied mathematics, but also - and thus building interdisciplinary bridges - about acoustics, instructions for figured bass, church tones and the theory of modulation.
Social Commitment
Müller was a full member of the Marburg Society for the Advancement of All Natural Sciences. He was involved in a variety of ways in education and in the church environment for choral and church music. From 1818 until Freemasonry was banned by Elector Wilhelm II in 1824 , he was a member of the Marburg Lodge Marc Aurel zum Flammenden Stern.
Honors
The city of Marburg made Karl Reinhard Müller an honorary citizen on April 17, 1859, "because of his valuable contributions to science and as a former teacher at the pedagogy here for the good of the city".
Two letters of thanks were dedicated to him on the occasion of the golden jubilee of his doctorate in 1859, one by the mineralogist Friedrich Hessel, a second by Georg Theodor Dithmar under the title Professor Dr. Karl Reinhard Müller welcomed his grateful students on his fiftieth anniversary as a doctor on April 17, 1859 .
