The life of Rudolf Nissen: advancing surgery through science and principle

Rudolf Nissen (1896-1981) was a surgeon whose career began in Germany during the first third of the 20th century, a period of rapid progress in biomedical technology, during which neurosurgery, anesthesiology, and other specialties emerged. A protégé and later close colleague of thoracic surgery pioneer Ferdinand Sauerbruch (1875-1951), Nissen resigned from the Berlin Charité Clinic and left Germany in 1933, in response to the rise of Nazi fascism. Throughout his subsequent career in Istanbul, Turkey, the American cities of Boston and New York, and finally Basel, Switzerland, Nissen developed innovative surgical techniques, advocated for patient-centered medical education, and promoted surgical subspecialization. A lifelong proponent of clear scientific writing, Nissen expressed, in extensively published work, his philosophy that progress in surgery depends critically on rigorously applying the scientific method, upholding professional integrity, and respecting human dignity.
