Biography of Siegmund Exner

Siegmund ExnerSiegmund Exner was the son of Franz Serafin, professor of philosophy and a school reformer, and Charlotte Dusensy. Like himself, his brothers Exner, Karl Exner and Franz-Serafin Exner later became famous professors.

Siegmund Exner attended the Akademische Gymnasium and began his medical studies in 1965. He first studied in Vienna under Ernst Wilhelm Ritter von Brücke (1819-1892), then in Heidelberg under Hermann Ludwig Ferdinand von Helmholtz (1821-1894). He received his doctorate on December 23, 1870. From 1871 he was an assistant at the physiological institute at the University of Vienna, becoming professor extraordinary there in 1875.

At the physiological institute Exner met the neurologist Josef Breuer (1842-1925) and Sigmund Freud (1856-1939), who conducted important neurophysiologic investigations there between 1876 and 1882. Both these two neurologists turned psychologists are said to have influenced Exner greatly.
In 1891 he succeeded Ernst von Brücke as professor of physiology and leader of the hygienic institute. In 1894 he was called to the ministry of culture and education, and in 1898 received the title of k.u.k. Hofrat, while retaining his chair. Exner remained head of the physiological institute at the University of Vienna until 1917. He received honorary doctorates from the universities of Leipzig and Athens.

From 1910 Exner was president of the Medical Society of Vienna – die Gesellschaft der Ärzte in Wien. In 1917 he was raised to the nobility for his contributions to medical-physiological education.

Siegmund Exner was married to Emilie, née von Winiwarter (1850-1909), who became an accomplished writer, publishing under the name of Felicie Ewart. They had two sons: Alfred von Exner Erwarten (1875), surgeon and university professor; and Felix Maria von Exner-Ewarten, meteorologist and university professor.

Research
Siegmund Exner is remembered for his important contributions to comparative physiology, brain research and perception psychology from a physiological viewpoint. One of his main fields of research was perception psychology with studies of the olfactory organs, on the sensitivity of retina regeneration, on colour contrast and on the vision of compound eyes. Especially important were his investigations on the localisation of behavioural functions in the brain, as well as his work on the functional architecture of the optical cortex.
