Heinrich Julius Adolph Robert Hartig (born May 30, 1839 in Braunschweig , † October 9, 1901 in Munich ) was a German forest scientist . He was mainly active as a forest botanist and plant pathologist . Hartig was an eminent mycologist . Its official botanical author abbreviation is " R.Hartig ".
The son of the forest scientist Theodor Hartig studied forest science in Berlin from 1863 to 1864 and then worked in forest management until 1866 . In 1866 he received his doctorate at the University of Marburg and in 1867 was offered a position at the Eberswalde Forest Academy . There he held lectures on forest botany from 1869 and in 1871 took over the management of the plant physiological research institute.
In 1878 Hartig was appointed professor of forest botany at the Ludwig Maximilians University in Munich .
Hartig, who gave the first suggestion for a scientific expansion of the pathology of forest species, is considered to be the founder of forest phytopathology together with Moritz Willkomm (1821–1895) . In 1878 Hartig first described the so-called beech complex disease, the economically most important beech disease. Likewise, the fungus Herpotrichia parasitica , which causes the fir needle tan , was discovered by Hartig in 1883 and described in 1884. Hartig was also considered one of the leading researchers of the real dry rot ( Serpula lacrymans ), on which he published a monograph in 1885 .
With his work on the structure of wood, he is also one of the founders of scientific wood science.
His studies on mycorrhizal formation in forest trees are also outstanding . The dense network of ectomycorrhizal fungi that is formed between the bark cells of the plant roots is named after him as Hartig's network .
Phellinus hartigii (Allescher et Schnabl), a porling that occurs mainly on silver fir and was examined in detail by Hartig, is named after him. There is also a Robert-Hartig-Strasse in Munich in his honor. In 1888 he was elected a member of the Leopoldina .
