Gonyak Ivan Konstantinovich (1856 - 1914?). Painter. He studied at the Kyiv Drawing School, then at the Academy of Fine Arts in M. Klodt. He lived in Petrograd, then in Rostov-on-Don (1920-30th years).. Participated in exhibitions since 1896 (Kiev OPH; AX; Petrograd Society of Artists, etc.). He painted mostly landscapes.
Only bothers me the date of death. In other publications I met date 'approx. 1941 ". Maybe, who knows what is correct?
