Professor Barbara Krupa-Wojciechowska was born on 12 April 1930 in Warsaw, where during World War II she completed primary school and two forms of lower secondary school in secret classes. In the middle of the Warsaw Uprising, she was deported to Germany. In 1949, she obtained her high school diploma and began studies at the Faculty of Medicine at the Medical Academy in Gdańsk (now the Medical University of Gdańsk). While still a student, in 1953, she began work as a deputy assistant at the 2nd Department of Internal Medicine, now the Department of Hypertension and Diabetology, where she spent her entire professional life, successively taking up the positions of assistant (1954), assistant professor (1964) and associate professor (1970).

In 1958, she passed the first-degree specialisation examination, and in 1964 the second-degree specialisation examination in internal medicine. In 1973, with the introduction of new specialties, she obtained specialisation in nephrology based on her clinical experience and scientific achievements. She introduced simultaneous hemodynamic and radioimmunological examinations of renin and aldosterone, which at that time offered the possibility of a holistic approach to the pathophysiology of arterial hypertension and the indication of therapy targeting.

Professor Barbara Krupa-Wojciechowska was an academic teacher and educator of generations of physicians, many of whom obtained their doctoral and postdoctoral degrees and professorships in subsequent years. She collaborated with researchers from, among others, the United Kingdom, Sweden, and the United States in scientific research and in organising foreign exchanges for the staff of the units she headed.
