Life

The son of the forest scientist Theodor Hartig studied from 1863 to 1864 in Berlin Forestry Science and was followed up in 1866 in the Forest Service operates. In 1866 he received his doctorate at the University of Marburg, and in 1867 he obtained a professorship at the Academy of Forestry Eberswalde.

1878 Hartig received a reputation as a professor of Forest Botany at the Ludwig- Maximilians- University of Munich.

Hartig, who gave the first suggestion for a scientific development of pathology unused forestry tree species, is considered together with Moritz Will Come (1821-1895) as the founder of Forest Phytopathology. So described Hartig in 1878 for the first time the so-called book - complex disease, the most economically important disease book. Likewise, the fir - needle tan -causing fungus Herpotrichia parasitica was discovered by Hartig in 1883 and described in 1884. Hartig was also regarded as one of the leading explorers of dry rot ( Serpula Lacrymans ), about which he published a monograph in 1885.

With his work on the structure of the wood he is also one of the founders of scientific wood science.

Outstanding are his studies on Mykorrhizabildung of forest trees. Thus, the dense network of ectomycorrhizal fungi, which is formed between the cortical cells of the plant root, named after him as the HARTIG network.

Phellinus hartigii ( Allescher et Schnabl ), a Polypore, which occurs mainly on silver fir and was studied in detail by Hartig, is named after him. In his honor, there in Munich also a Robert Hartig road.
