The English chemist and physicist Michael Faraday, b. Sept. 22, 1791, . 25, 1867, is known for his pioneering experiments in electricity andmagnetism. Many consider him the greatest experimentalist who ever lived.

Several concepts that he derived directly from experiments, such as lines of magnetic force, have become common ideas in modern physics.

Faraday was born at Newington, Surrey, near London. He received little more than a primary education, and at the age of 14 he was apprenticed to a bookbinder. There he became interested in the physical and chemical works of the time. After hearing a lecture by the famous chemist Humphry Davy, he sent Davy the notes he had made of his lectures. As a result Faraday was appointed, at the age of 21, assistant to Davy in the laboratory of the Royal Institution in London.

During the initial years of his scientific work, Faraday occupied himself mainly with chemical problems. He discovered two new chlorides of carbon and succeeded in liquefying chlorine and other gases. He isolated benzene in 1825, the year in which he was appointed director of the laboratory.

Davy, who had the greatest influence on Faradays thinking, had shown in 1807 that the metals sodium and potassium can be precipitated from their compounds by an electric current, a process known as electrolysis.

Faradays vigorous pursuit of these experiments led in 1834 to what became known as Faradays laws of electrolysis.
