Sir Humphry Davy (1778-1829)

Humphry Davy was one of the most brilliant scientists of the 19th century. As an apprentice to an apothecary he developed an interest in chemistry, and his first post was at the Pneumatic Institution in Bristol, where he studied the effects of nitrous oxide, 'laughing gas'.

In 1801 he was appointed to the Royal Institution as Director of the Laboratory and Assistant Chemistry Lecturer. Here his work established the science of electrochemistry, and he isolated potassium, sodium, magnesium, barium, strontium and calcium by electrolysis. He also carried out research into the tanning industry and agricultural chemistry, as well as observing the electric arc. He was knighted in 1812, and in 1813 he appointed a bookbinder's apprentice, Michael Faraday, as his scientific assistant. His later successes included the isolation of iodine, the development of his famous miners' safety lamp and appointment as President of the Royal Society.
