Davy, Sir Humphry (1778-1829)

Sir Humphry Davy (1778-1829)was and English scientist, best remembered for his invention of the miner's safety lamp in 1815.
His lamp prevented the explosion of air containing methane, or fire-damp, a gas common in coal mines.
The lamp's flame was protected by a fine wire mesh to separate it from the explosive gases.
Davy was born and educated in Cornwall, England. When he left school, he went to work for a doctor.
He gave this up and took charge of a laboratory in Bristol Where he studied the effects of gases on people.
He discovered that nitrous oxide (laughing gas ) could be used as an anesthetic.
Later, in London, he studied how electricity is stored in batteries.
He also discovered that materials could be separated into their Elements by passing an electric current through them.
