Hans Berger

Died 1 Jun 1941 at age 68 (born 21 May 1873).German psychiatrist who recorded the first human electroencephalogram (EEG). In 1929, he devised a system of electrodes which he attached to his son's skull, and connected to an oscillograph. This gave a recording of brain waves - the rhythmic changes in electric potentials. The most prominent of these rhythms he labelled "alpha waves" and "beta waves."
