German physician, pioneer psychiatrist, and medical professor, known for his measurement of mean healthy human body temperature of 37 °C (98.6 °F), now known more accurately to be about 36.8 °C (98.2 °F).
While serving as Professor and Medical Director of the Leipzig University hospital he introduced clinical pedagogy, combined with a rigorous methodology of diagnosis, and empirical observation of patients. He introduced temperature charts into hospitals, holding that fever is not a disease, but a symptom. The thermometer he used was reportedly a foot long, and required 20 minutes to register the temperature.
He was known for his lectures on psychiatry and on the "pathology and therapy of illnesses of the nervous system." He described an extremely rare eponymous syndrome which consists of retroperitoneal bleeding from the kidney which tracks into the surrounding tissues. This may be due to benign or malignant disease.
Wunderlich's books include Handbuch der Pathologie und Therapie (1856) and Das Verhalten der Eigenwärme in Krankheiten [The behaviour of self-warmth in diseases] (1868). He died on 25 September 1877 at age 62 in Leipzig.
