From 1885 to 1889 he studied chemistry at the University of Dorpat , then he took another semester of mathematics. In 1889 he moved as Candidatus chemistriae to the chemical laboratory of the Technological Institute of Saint Petersburg , where he became the assistant to Friedrich Konrad Beilstein . Due to illness, he gave up this position in 1891 and only continued his chemistry studies at the University of Leipzig in 1894 .

Luther received his doctorate in April 1896, the title of his dissertation was: Electromotoric force and equilibrium distribution . Afterwards Luther became assistant to Wilhelm Ostwald at the Physico-Chemical Institute of the university. He completed his habilitation on June 20, 1899 with the text The shift in the equilibrium between the halogen compounds in silver and the free halogen caused by light . On December 22nd, 1899 he was given the venia legendi , at the same time he was appointed private lecturer.

On April 1, 1904, Luther was appointed associate professor and was given a teaching position in physical chemistry . He temporarily represented Ostwald as head of the institute, but did not succeed him after his sick leave. In 1906, however, Luther became head of the photochemical department at the Physico-Chemical Institute of the University of Leipzig, and he turned down a professorship at the TH Hannover offered him in 1907 . The Saxon Academy of Sciences in Leipzig accepted him as a member in 1907.

On April 1, 1908, Luther was appointed full professor at what was then the TH Dresden . The Institute for Photography was only re-established this year with the help of the Dresden- based photographic industry, and Luther became the institute's first director.
