Humphry Davy (17 December 1778, Penzance, Cornwall – died 29 May 1829, Geneva) was an English chemist, physicist and inventor.

He separated the compounds with electrical energy and obtained the elements in pure form. In 1799, he found the laughing effect of nitrous oxide, through his work at the hospital in Bristol, where patients with lung cancer were treated; He studied the physiological effects of various gases through his own experiments.

He came to London from Bristol in 1803 and became a member and later president of the Royal Society.

in order in 1807; He passed an electric current through the molten ash, and in this way he succeeded in separating the element he called potassium first, and then the element sodium from soda, and the following year he found barium, strontium and calcium. He determined that the acid property was due to the presence of hydrogen, and concluded that acids and anhydrides were different. He also found electric arc by making measurements on electrolysis products. He worked with Faraday on the liquefaction of gases.

He entered the French Academy of Sciences in 1813. He carried out many chemical decompositions at the royal institute with the aid of a specially developed battery of two thousand elements, which was established by donations. In 1817, oxidation reactions (hydrogen, alcohol) discovered the catalytic properties of platinum. He made the wire cage safety lamp used against firedamp explosions in mines. He has a work called Consolions in Travel or the Last Days of a Philosopher.

Sir Humphry Davy introduced the light bulb to the British Royal Academy in 1802. This invention was brought into practice by Thomas Edison 75 years later.
