Josef Breuer (German: [ˈbʀɔʏɐ]; 15 January 1842 – 20 June 1925) was a distinguished Austrian physician who made key discoveries in neurophysiology, and whose work in the 1880s with his patient Bertha Pappenheim, known as Anna O., developed the talking cure (cathartic method) and laid the foundation to psychoanalysis as developed by his protégé Sigmund Freud.
Born in Vienna, his father, Leopold Breuer, taught religion in Vienna's Jewish community. Breuer's mother died when he was quite young, and he was raised by his maternal grandmother and educated by his father until the age of eight. He graduated from the Akademisches Gymnasium of Vienna in 1858 and then studied at the university for one year before enrolling in the medical school of the University of Vienna. He passed his medical exams in 1867 and went to work as assistant to the internist Johann Oppolzer at the university.
Breuer, working under Ewald Hering at the military medical school in Vienna, was the first to demonstrate the role of the vagus nerve in the reflex nature of respiration. This was a departure from previous physiological understanding, and changed the way scientists viewed the relationship of the lungs to the nervous system. The mechanism is now known as the Hering–Breuer reflex.
Independent of each other in 1873, Breuer and the physicist and mathematician Ernst Mach discovered how the sense of balance (i.e., the perception of the head’s imbalance) functions: that it is managed by information the brain receives from the movement of a fluid in the semicircular canals of the inner ear. That the sense of balance depends on the three semicircular canals was discovered in 1870 by the physiologist Friedrich Goltz, but Goltz did not discover how the balance-sensing apparatus functions.
