A biography of the life and achievements of chemist sir humphry davy

Davy was the elder son of middle-class parents, who owned an estate in Ludgvan. He was educated at the grammar school in nearby Penzance and, inat Truro.

His father, James, was a member of the Glassite sect of Christianity. James Faraday moved his wife and two children to London during the winter of from Outhgill in Westmorlandwhere he had been an apprentice to the village blacksmith.

The young Michael Faraday, who was the third of four children, having only the most basic school education, had to educate himself. Faraday was particularly inspired by the book Conversations on Chemistry by Jane Marcet.

Many of the tickets for these lectures were given to Faraday by William Dancewho was one of the founders of the Royal Philharmonic Society.

Faraday subsequently sent Davy a page book based on notes that he had taken during these lectures. Inwhen Davy damaged his eyesight in an accident with nitrogen trichloridehe decided to employ Faraday as an assistant. In the class-based English society of the time, Faraday was not considered a gentleman.

Faraday was forced to fill the role of valet as well as assistant throughout the trip.

The trip did, however, give him access to the scientific elite of Europe and exposed him to a host of stimulating ideas. They had no children. Well after his marriage, he served as deacon and for two terms as an elder in the meeting house of his youth.

This meeting house relocated in to Barnsbury Grove, Islington ; this North London location was where Faraday served the final two years of his second term as elder prior to his resignation from that post. During his lifetime, he was offered a knighthood in recognition for his services to science, which he turned down on religious grounds, believing that it was against the word of the Bible to accumulate riches and pursue worldly reward, and stating that he preferred to remain "plain Mr Faraday to the end".

In Faraday retired to live there. Faraday was specifically involved in the study of chlorine ; he discovered two new compounds of chlorine and carbon. He also conducted the first rough experiments on the diffusion of gases, a phenomenon that was first pointed out by John Dalton.

The physical importance of this phenomenon was more fully revealed by Thomas Graham and Joseph Loschmidt. Faraday succeeded in liquefying several gases, investigated the alloys of steel, and produced several new kinds of glass intended for optical purposes.

A specimen of one of these heavy glasses subsequently became historically important; when the glass was placed in a magnetic field Faraday determined the rotation of the plane of polarisation of light. This specimen was also the first substance found to be repelled by the poles of a magnet.

Faraday invented an early form of what was to become the Bunsen burnerwhich is in practical use in science laboratories around the world as a convenient source of heat. The liquefying of gases helped to establish that gases are the vapours of liquids possessing a very low boiling point and gave a more solid basis to the concept of molecular aggregation.

In Faraday reported the first synthesis of compounds made from carbon and chlorine, C2Cl6 and C2Cl4and published his results the following year.

In he discovered that the optical properties of gold colloids differed from those of the corresponding bulk metal. This was probably the first reported observation of the effects of quantum size, and might be considered to be the birth of nanoscience.

With this pile he decomposed sulfate of magnesia first letter to Abbott, 12 July Electromagnetic rotation experiment of Faraday, ca.

One of these, now known as the homopolar motorcaused a continuous circular motion that was engendered by the circular magnetic force around a wire that extended into a pool of mercury wherein was placed a magnet; the wire would then rotate around the magnet if supplied with current from a chemical battery.

These experiments and inventions formed the foundation of modern electromagnetic technology. In his excitement, Faraday published results without acknowledging his work with either Wollaston or Davy. The liquid battery right sends an electric current through the small coil A.

When it is moved in or out of the large coil Bits magnetic field induces a momentary voltage in the coil, which is detected by the galvanometer G. From his initial discovery inFaraday continued his laboratory work, exploring electromagnetic properties of materials and developing requisite experience.

InFaraday briefly set up a circuit to study whether a magnetic field could regulate the flow of a current in an adjacent wire, but he found no such relationship.Learn more about this influential scientist’s work.

Early education

Humphry Davy was born on 17 December in Penzance in Cornwall. He was apprenticed to a surgeon and aged 19 went to Bristol to study science.

There he investigated gases. He prepared and. Jöns Jacob Berzelius: Jöns Jacob Berzelius, one of the founders of modern chemistry. He is especially noted for his determination of atomic weights, the development of modern chemical symbols, his electrochemical theory, the discovery and isolation of several elements, the development of classical analytical techniques.

Sir Humphry Davy, 1st Baronet FRS MRIA (17 December – 29 May ) was a British chemist and inventor.

He is probably best remembered today for his discoveries of several alkali and alkaline earth metals, as well as contributions to the discoveries of the elemental nature of chlorine and iodine.

Sir Humphry Davy, widely considered to be one of the greatest chemists and inventors that Great Britain has ever produced, is highly regarded for his work on various alkali and alkaline earth metals, and for his valuable contributions regarding the findings of the elemental nature of chlorine and iodine.

Sir Humphry Davy, 1st Baronet PRS MRIA FGS FRS (17 December – 29 May ) was a Cornish chemist and inventor, who is best remembered today for isolating, using electricity, a series of elements for the first time: potassium and sodium in and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine.
