YELENKIN, Aleksandr was born on September 16, 1873 in Warsaw.
1897 graduate Warsaw University.
1898 — 1942 worked at Saint St. Petersburg Botanical Gardens (later Botanical Institute, Union of the Soviet Socialist Republics Academy of Sciences). 1898 founded Spores Herbarium (now Department of Spore Plants, Botanical Institute). Pioneered lichenology in Russia.
Proposed theory of endoparasitosaprophytism, explaining the relations between fungus and algae in a lichen symbiosis, whereby the fungus lives as a parasite on the living algae and feeds saprophytically on dying algae contained in the body of the lichen. Devised a new classification of lichens which he called combinative and pointed out that this was no phylogenetic system but enabled corrections to be made to the structure of the natural system. Wrote unique monograph Sinezelyonyye vodorosli USSR (The Blue-Green Algae of the Union of the Soviet Socialist Republics) (2 volume, 1936-1949).
Also published unique Flora mkhov Sredney Rossii (The Moss Flora of Central Russia) (1909).
Religious books are outdated, because laws by nature have to change with the advance of societies and technology.
Marxism–Leninism as the only truth could not, by its very nature, become outdated.
