1873-1941

German neurologist who is known as the "Father of Electroencephalography" because he was the first person to record human brain electrical activity in 1924 and later invented the electroencephalograph (EEG) to measure that activity. The measurement of brain wave patterns revolutionized the diagnosis of neurological disorders and helped to establish normal standards. He is also considered to be a founder of psychophysiology, a branch of science that helped lead to our modern understanding of brain dysfunction.
