Młokosiewicz was born in
Warsaw, into a wealthy and aristocratic family, son of Polish general
Franciszek Młokosiewicz. He spent his childhood in Warsaw and
Omięcin. At his father's request, from 1842 he attended the cadet corps in
Brześć, however, not interested in a military career, he returned to Warsaw in 1846 and continued his education privately. Despite his innocence of the charges, he was sentenced to six years' enforced residence in the province of
Voronezh, and his botanical collections were confiscated. In 1876 after restrictions had been lifted Młokosiewicz explored the mountains of
Dagestan, and two years later returned to Persia, travelling as far as
Balochistan. On his return he was appointed Inspector of Forests for the
Signakhi District, remaining at Lagodekhi for the rest of his life. He supplied foreign museums with botanical and zoological specimens. He maintained contacts with museums and institutions in his hometown of Warsaw. Młokosiewicz discovered 60 species of plants and animals. Species that he discovered and that were named after him include the
Caucasian black grouse (
Tetrao mlokosiewiczi) and the
golden peony (
Paeonia mlokosewitschii). Beginning in 1889, Młokosiewicz urged the protection of the forested area at Lagodekhi; in 1912, three years after his death, the Russian viceregent in the Caucasus region declared what is now
Lagodekhi Protected Areas. Młokosiewicz's other contributions include inventing a method to eradicate
malaria in Georgia, which won him widespread respect among the local people, and assisting the Georgian people as a social activist, for example by founding an agricultural school. Młokosiewicz dies in 1909 and was buried at a local cemetery in Lagodekhi, Georgia. ==See also==
