1. Hans Berger is best known as the inventor of electroencephalography in 1924, which is a method used for recording the electrical activity of the brain, commonly described in terms of brainwaves, and as the discoverer of the alpha wave rhythm which is a type of brainwave.
Hans Berger was born in Neuses, Saxe-Coburg and Gotha, Germany.
The driver of the artillery battery halted the horses in time, leaving the young Hans Berger shaken but with no serious injuries.
Hans Berger collaborated with two famous scientists and physicians, Oskar Vogt and Korbinian Brodmann, in their research on lateralization of brain function.
In 1924, Hans Berger succeeded in recording the first human electroencephalogram, a term he coined.
Hans Berger seemed to me to be a modest and dignified person, full of good humour, and as unperturbed by lack of recognition as he was later by the fame it eventually brought upon him.
In 1938, at the retirement age of 65, Hans Berger was made Professor Emeritus in Psychology.
In 2005, Dr Susanne Zimmermann, medical historian at the University of Jena, found evidence that Hans Berger had not been forced into retirement but had "served on the selection committee for his successor" Berthold Kihn, who was sacked as a Nazi after the war.
The gentleman allowed Hans Berger to insert a liquid-filled rubber tube through the hole in his skull.
Hans Berger noticed that the pen recorded waves that would change when he asked his conscious participant to perform different cognitive tasks.

Hans Berger followed this work with his most significant contribution to modern science.
Hans Berger's patient gave him the opportunity to apply Caton's technique to a human.
In 1924, Hans Berger made the first EEG recording of human brain activity and called it Elektrenkephalogramm.
Hans Berger studied and described for the first time the nature of EEG alterations in brain diseases such as epilepsy.
Hans Berger's method involved inserting silver wires under the patients scalp, one at the front of the head and one at the back.
Hans Berger then switched to the string galvanometer and later to a double-coil Siemens recording galvanometer, which allowed him to record electrical voltages as small as one ten-thousandth of a volt.
