Rutherford was born on 3 November 1749, the son of Anne Mackay and Professor John Rutherford (1695–1779).. He began college at the age of 16 at Mundell's School on the West Bow close to his family home, and then studied medicine under William Cullen and Joseph Black at the University of Edinburgh, graduating with a doctorate (MD) in 1772. From 1775 to 1786 he practiced as a physician in Edinburgh.
He was a professor of botany at the University of Edinburgh and the 5th Regius Keeper of the Royal Botanic Garden Edinburgh from 1786 to 1819. He was president of the Royal College of Physicians of Edinburgh from 1796 to 1798.
He died in Edinburgh on 15 December 1819.
In 1786 he married Harriet Mitchelson of Middleton.
Rutherford was the maternal uncle of the novelist Sir Walter Scott.
Isolation of nitrogenEdit
Rutherford discovered nitrogen by the isolation of the particle in 1772. When Joseph Black was studying the properties of carbon dioxide, he found that a candle would not burn in it. Black turned this problem over to his student at the time, Rutherford. Rutherford kept a mouse in a space with a confined quantity of air until it died. Then, he burned a candle in the remaining air until it went out. Afterwards, he burned phosphorus in that, until it would not burn. Then the air was passed through a carbon dioxide absorbing solution. The remaining component of the air did not support combustion, and a mouse could not live in it.
Rutherford called the gas (which we now know would have consisted primarily of nitrogen) "noxious air" or "phlogisticated air". Rutherford reported the experiment in 1772. He and Black were convinced of the validity of the phlogiston theory, so they explained their results in terms of it.
