Humphry Davy was born in December 17 1778 and died in 5-29-1829 and he died of heart failure. he invented the arc lamp in 1808 and miners safty lamp in 1815. he discovered sodium, cool flames, laughing gas, calcium, barium, boron, potassium,

magnesium. He was knighted by king George the 3rd in 1812. He was president of the royal society. He damaged his eye

sight in a libratory accident with hydrogen dichloride. he did al lot of his experiments on himself. His father died in 1794, and Davy, in an effort to help support his family, became an apprentice to a surgeon-apothecary. He soon found that when he

passed electrical current through some substances, these substances decomposed, (a process later called electrolysis). In 1801, the Royal Institution in London engaged Davy as a public lecturer. In 1827, Davy became seriously ill. The illness was

later attributed to his inhalation of many gases over the years. While in Rome, he had a heart attack and he later died on

May 29, 1829 in Geneva, Switzerland. His first Bakerian Lecture won a prize from Napoleon, even though France and

England were at war. Davy's chemical lectures and demonstrations were brilliantly presented and became a fashionable

social event. After reading Antoine Lavisher’s Traite Elementaire, Davy in 1797 became interested in chemistry. He

"breathed 16 quarts of the gas in seven minutes" and became "completely intoxicated". Sir Humphry Davy concocted a

giant battery in the basement of Britain's Royal Society. Buried, Cimetière des Plainpalais, Geneva, Switzerland.

Humhry Davy was born on December 17, 1778 and died in May 29, 1829. When he was young he grew up poor and his dad

was a wood carver (died in 1794). Humphry did most of his research by him self but then got an assistant his name was

Michael Faraday (1967). He went to school at Truro Grammer School. He was a professor in chemistry.

He got critically ill from years of inhaling gases. He came close to dieing in an experiment because there was a leek on a

hydrogen tank in an enclosed room. Humphry was president of the royal society. He was a teacher and his lectures

attracted people from all around. He discovers barium, calcium, magnesium, potassium, sodium, and boron.

He published a book on fly fishing. He had a stroke at forty nine and he died when he was 50 years old. He was knighted

bye king George the 3rd in 1812. He invented the carbon arc lamp and safer miner hat that had no open flame. He

discovered 6 elements and cool flame that burn at 120 Celsius.


 * Sir Humphry Davy**

He damaged his eye sight for a libratory experiment with nitrogen chloride. And Davy discovered laughing gas in 1815. Sir

Humphry died of heart failure in 1829. His assistant, Michael Faraday was an inventor just like him. Michael invented the

electric motor, the balloon and more. Sir Humphry came up with the idea of the light bulb but never made.

Many time people took credit for his inventions and his ideas instead of him. He made the miners safety safer then the fist

design by getting rid of the open flame and put in a light bulb. Sir Humphry made a giant battery in the basement of the

British Royal Society it took up 889 square feet in 1813. He discovered how to keep copper sheathing from corrosion in salt

water. Faraday Humphrey’s assistant finally got into the British Royal Society. Humphry discovered a lot of the alkali and

alkali earth metals. Sir Humphry had one brother and three sisters. Davy was doing so well in school that one of his

teachers suggested that he should go to a better school than that one. Davy fell in love with a female named Mrs. Anna

Beddoes she was a friend and a lover to him. Since he made a safer head lamp for miners the mines could go farther and

safer in to the mines without the danger of the explosive gases blowing up from the open flame on there head.

Davy loves experimental science he thought it was very interesting to him at the time. In 1779 Davy visited London for his

first time. He had a costume built portable gas chamber for his nitrous oxide inhalation experiment. He did his own research

on nitrous oxide and discovered it was a great to get rid of a bad hangover. Sir Humphry Davy taught him self multiple

subjects like theology and philosophy, poetics, seven languages, and several sciences, including chemistry. Davy took a

position that they used newly discovered gases to try to get rid of diseases. When his father died he took reasonability as

the oldest and become an apprentice as a surgeon-apothecary witch got him interested in medicine. When Davy held his

lectures he would attract a little less than 1000 people.

In 1808 he read his third Bakerian lecture, one of his longest ones he has wrote. A few months after his marriage he

published the first and only volume of his elements of philosophy. His wife was his first assistant but soon replaces her with

Michael Faraday. In 1821 he was busy with electrical experiments. In 1822 he did investigations with fluids and containers

in cavities of crystals in rocks. The book he wrote on fly fishing was called the complete angler. On the 11th he was married

to Mrs. Apreece, daughter and heiress of Charles Kerr of Kelso, and a distant connection of Sir Walter Scott. He gave a

speech on the chemical principles of tanning.
