Born in Vienna, Austria, Professor Braunwald fled Nazi persecution as a child to Switzerland, then England, and eventually settling in the United States. There he trained in internal medicine and cardiology and began a career defined by curiosity, courage, and an unwavering commitment to patients. From early haemodynamic work at the National Institutes of Health to transformative academic leadership at Harvard Medical School and Brigham and Women’s Hospital, he helped build institutions, teams, and ideas that shaped cardiovascular medicine for generations.
