Born in 1857. At the end of the course at Moscow University, was a lab assistant at the department of botany at the Agricultural Academy of Peter, then a lab assistant at the department of plant physiology at the St. Petersburg University. Investigation of the parasite birch fruits produced H. Voronin on the idea, initiated a number of works on the morphology amentaceous, due to the fact that H. revealed features of fertilization in this group of plants, studying the disease ovaries birch. At the same time, H. was launched in conjunction with Voronin work on the history of the pouch fungus (Sclerotinia heteroica), representing the case raznodomnogo parasite between marsupials mushrooms. In 1894, H. received a Master of botany for his thesis: "The disease catkins of birch, in 1895 - a doctorate for his thesis" On the birch and the morphological significance halatsogamii ". The most noteworthy discovery of double fertilization in angiosperms. Contains a professor at Kiev University and a corresponding member of the Academy of Sciences.
