Recording the first human electroencephalogram in 1924 initiated a fundamental shift in neurological diagnostic practices. This invention, which translated electrical brain activity into observable data, earned its developer, Hans Berger, a lasting position in the history of medicine. His work fundamentally altered how researchers understand the relationship between human subjective experience and physiological brain functions.
Early academic pursuits and military influence
Born in Neuses in 1873, Berger attended the Gymnasium Casimirianum Coburg before matriculating at the University of Jena in 1892. Initially intending to study astronomy, he soon pivoted to medicine. A significant turning point in his life occurred during his mandatory military service when a near-fatal accident with a horse-drawn cannon prompted a lasting obsession with telepathy and the transmission of thoughts. This event directed his medical research toward finding the physiological basis for psychic energy.

After earning his medical degree in 1897, Berger joined the staff of the Jena clinic under Otto Ludwig Binswanger. He advanced steadily, becoming a senior lecturer in 1906 and a physician-in-chief by 1912. He eventually assumed the chair in psychiatry and neurology in 1919. During his tenure, he collaborated with figures such as Oskar Vogt and Korbinian Brodmann, focusing on brain function lateralization. In 1927, he served as the rector of the University of Jena.
Development of the EEG
Berger spent years investigating psychophysiology and brain temperature, utilizing a patient with a cranial defect to monitor brain pressure. Following the work of Richard Caton, he sought to record electrical potentials directly from the human brain. Although he achieved his first successful EEG recording in 1924, he waited until 1929 to publish his results. Initial reception in the German medical community was dismissive, with critics labeling him a crank. International validation arrived only after 1934, when Edgar Douglas Adrian and B. H. C. Matthews confirmed his observations.
Final years and institutional associations
Upon reaching the age of 65 in 1938, Berger was appointed Professor Emeritus. Contrary to historical myths regarding his forced retirement by the Nazi regime, evidence suggests he participated in the selection of his successor. Records confirm that he served on the Court for Genetic Health, an entity involved in forced sterilizations. Following a period of clinical depression and a severe skin infection, Berger died by suicide in Jena in 1941.
