Hans Berger

The German psychiatrist Hans Berger was the first person to prove the existence of electric potentials (voltage fluctuations) in the human brain using an amplifying machine (an electroencephalograph).

Before this, the English physician Richard Caton (1842-1926) had proven the existence of similar potentials in dogs.
