Original edition of this astronomical dissertation thesis submitted by C.F. Tresenreuter under the supervision of the astronomy professor at the University of Altdorf, Johann Heinrich Müller.

From 1687 to 1692, Müller worked as an assistant to Georg Christoph Eimmart (1638-1705) at the Nuremberg Observatory, found by Eimmart. Müller began his studies in 1692 in Altdorf. In 1697, he moved to Giessen and two years later, in 1699, to Tübingen. In 1705, he became a professor of physics at the gymnasium in Nuremberg, and following Eimmart's death, he became director of the Nuremberg Observatory. In 1706, he married Maria Clara Eimmart (1668-1707), who had also been active as an astronomer since her youth. She died while giving birth to a son, who did not survive. In 1709, Müller became a professor of mathematics at the University of Altdorf, where he moved in 1710 to succeed Johann Wilhelm Baier. From 1711 to 1713, the second Altdorf Observatory was built under Müller's supervision. In 1713, he also assumed the position of director of the new observatory. He gave lectures on meteorology, mathematical geography and cartography. In 1728, he was elected a foreign member of the Prussian Academy of Sciences, and in 1730, he was elected to the Leopoldina Academy (cf. S. Günther, Müller, Johann Heinrich, in: “Allgemeine Deutsche Biographie”, vol. 22, Leipzig, 1885, pp. 583-585).

Tresenreuter later became a preacher and acquired a position as principal and professor of theology at the University of Altdorf.
