history of minamata disease

In May, 1956, four patients from Minamata, Japan, a city on the west coast of the southern island of Kyushu, were admitted to the hospital. The physicians were puzzled by the symptoms the patients held in common: severe convulsions, bouts of psychosis, loss of consciousness and coma. Finally, after a very high fever, all four patients died.
