Vladimir Andreevich Tranzschel

Vladimir Andreevich Tranzschel (1868 to 1942) was a Russian and later Soviet botanist, mycologist and plant pathologist, especially an expert on rust fungi. He graduated from Saint Petersburg University in 1889, became an assistant at the Imperial Forestry Institute, and from 1895 to 1899 co-edited the exsiccata Fungi Rossiae exsiccati. He later became curator at the Botanic Garden of the Imperial Academy of Sciences, remained affiliated with the Academy for the rest of his career and from 1912 was senior botanist. He is particularly known for Tranzschel's Law on the telia of microcyclic rust fungi, which helps identify the aecial host of a suspected heteroecious rust and which modern molecular investigations have confirmed, and the rust fungus genus Tranzschelia was named in his honour.
