Named after Varvara Rudneva - Russian physician (1844-1899).
Varvara Kashevarova Rudneva was a Russian physician. Her exam was thereby unique in Russia at the time and was given a lot of attention. Despite the ban against women studying at University, she was given a special dispensation to study by promising to treat only woman patients who refused to be treated by male doctors because of religious reasons.
