Valentyna Radzymovska (1886–1953) was a Ukrainian physician and scientist who was one of the first in the world to study the influence of acid-base balance on living cells and laid the foundations of the Ukrainian school of physiologists and biochemists. A professor at Kyiv and Lviv institutions, a participant in the liberation struggle and public and political life, she survived arrest in the case of the “Union for the Liberation of Ukraine”, Nazi occupation, and emigration to Germany and the USA. Leading figures of the Ukrainian movement gathered in her Kyiv apartment, and her scientific works combined laboratory experiments with concern for the health of children and tuberculosis patients. The portrait recreates the image of a woman for whom science, Ukraine, and human dignity were inseparable.
