Constantin von Economo held the distinction of being the first Austrian to secure an international pilot's license in 1912, balancing his aeronautical ambitions with a rigorous career in clinical medicine. His work spanning the early 20th century redefined the scientific understanding of the human brain through detailed mapping and the identification of a previously unknown neurological condition.
Medical Education and Training
Born in 1876 in Brăila, Romania, von Economo initially pursued mechanical engineering at the TU Wien in 1893 before transitioning to medicine. He earned his medical degree in 1901 and subsequently worked as an assistant to Sigmund Exner. His formative years included clinical rotations across Europe, where he refined his expertise in psychiatry, histology, and neurology under various mentors in Paris, Nancy, Strasbourg, Berlin, and Munich.

During his service as a military physician in World War I, von Economo encountered patients displaying symptoms that he classified as encephalitis lethargica. This acute inflammation of the grey matter caused widespread illness between 1915 and 1924. He detailed three distinct clinical manifestations: the somnolent-ophthalmoplegic form, the hyperkinetic form, and the amyostatic-akinetic form. His research provided the pathology for this condition, later known as Von Economo’s Disease, and spurred his interest in identifying the brain’s sleep centers.
Cytoarchitectonic Mapping
In 1912, von Economo began a comprehensive project to chart the human cerebral cortex. Collaborating with Georg N. Koskinas starting in 1919, he published 'Die Cytoarchitektonik der Hirnrinde des erwachsenen Menschen' in 1925. This two-volume work included a textbook and an atlas containing 112 microphotographic plates. The researchers divided the cortex into seven lobes, operating on the hypothesis that distinct cellular architecture corresponds to specific functional differences within the brain.
Academic and Aviation Career
Von Economo served as a professor of psychiatry and neurology at the University of Vienna, where he was appointed head of a new department of brain research in 1931. Beyond his clinical duties, he presided over the Austrian Aero-Club from 1910 to 1926. He balanced his scientific publications, which totaled approximately 150 articles, with active military service as a pilot in South Tyrol during 1916.

Questions readers ask
What is Von Economo’s Disease?
It is encephalitis lethargica, an acute inflammation of the grey matter that occurred in worldwide epidemics between 1915 and 1924, causing symptoms ranging from somnolence to parkinsonian-like motor rigidity.
What was the significance of his cytoarchitectonic atlas?
It provided a foundational map of the human cortex, dividing it into seven lobes based on cellular structure to support future research into the localization of brain functions.
