A son of a minor government official, Niesłuchowski graduated from Saint Petersburg Institute of Technology and worked as a railway engineer. Because of a leg disease he needed crutches to walk. A collection of his Belarusian poems and translations, Viazanka (A Bundle) was published in 1903, several years after his death, earning him a place among the founders of the modern Belarusian literature.
