The French Neurologist
French neurologist Guillaume Duchenne was a famous doctor who worked in an asylum in Paris. In his quest to determine how electrodes on a human being reacted when electrocuted. Although the electric shock was mild, the electrocution triggered repulsive facial expressions from the so-called ‘volunteers.’ His theory was that people’s emotions resulted from electrodes moving from a person’s heart to their face. By triggering different muscles, Guillaume was able to come up with these horrific facial expressions.
