Born in 1778, Sir Humphry Davy appropriately identified and named chlorine as an element in 1810, entertained an adoring public with experiments with gases, identified iodine as an element, experimented with electricity and the improvement of safety lamps for coal miners and was totally addicted to laughing gas (of which eventually led to his death). As a chemist, he did numerous studies which also allowed him to identify and name potassium, sodium, and eventually he works on voltaic cells (early form of electric batteries).
