Live and act

After finishing school in Schweidnitz in Silesia , Gustav Müller studied mathematics and natural sciences at the University of Leipzig from 1870 . During his studies in 1870 he became a member of the Leipzig fraternity Germania . In 1872 he moved to the then Friedrich Wilhelms University in Berlin , where he turned to astronomy under the influence of Wilhelm Foerster . From 1875 he came into contact with Hermann Carl Vogel , who at that time was busy building the Astrophysical Observatory in Potsdam . In 1877 Müller was awarded a Dr. phil. PhD. He then went to the Astrophysical Observatory Potsdam as an assistant, where he worked until the end of his scientific career.

Müller worked specifically in two scientific areas: photometry of the celestial bodies and analysis of the solar spectrum . He also assisted Hermann Carl Vogel between 1880 and 1882 with his spectroscopic observations of the stars. Müller presented a large number of papers on the measurement of the brightness of planets and comets as well as on the analysis of the solar spectrum, which appeared mainly in the Astronomical News and as publications of the Astrophysical Observatory Potsdam and were partly created in collaboration with Paul Kempf. At the end of his scientific career he published a three-volume work with Ernst Hartwig, History and Literature of the Light Change of the Stars, which were recognized as definitely changeable until the end of 1915, together with a catalog of the elements of their light change . Müller took part in several scientific expeditions abroad.

From 1896 to 1924 he was one of the secretaries of the Astronomical Society . 1917–1921 he was director of the Astrophysical Observatory. In 1886 Gustav Müller was elected a member of the Leopoldina . In 1918 he was accepted as a full member of the Prussian Academy of Sciences .
