The article, based on archival documents, reproduces the biography of Petro Ivanovych Havsevych (1883–1920), a well-known Ukrainian agricultural scientist, founder and first director of the Research Station of Medicinal Plants of the Institute of Agroecology and Nature Management of the National Academy of Agrarian Sciences of Ukraine in Lubny. It is emphasized that the first official biography, created by the wife of the scientist N. M. Singalevych, the Commissioner of National Education, a pedagogue, turned out to be a classic "proletarian" biography, which contained many inaccuracies and "white spots" in the life of P. I. Havsevych, and she made a lot of effort to ensure that all of her husband's "Personal Affairs" disappeared from the Ukrainian archives. The author, on the basis of a thorough analysis of P. I. Havsevych's creative heritage, which consists of more than 50 various scientific and popular science publications, some of which were introduced into scientific circulation for the first time, established that he was one of the most competent specialists in his field in the country. What remains important is the fact found in the archives that P. I. Havsevych, contrary to the ideological Bolshevik cliché, was not a "sincere revolutionary", but, on the contrary, had deep knowledge in theology and was a pious person, besides, sincerely in love with his work.

The publication raised the issue of commemorating famous agricultural scientists at the state level.
