DANIEL RUTHERFORD, M.D.
Born November 3, 1749. Died November 15, 1819.
Daniel Rutherford was born at Edinburgh and educated at the University of his native city. He took his degree of M.D. in 1772, and in the Thesis which he published upon this occasion, entitled 'De Aëre Fixo,' he pointed out for the first time a new gaseous substance, since distinguished by the name of Azote or Nitrogen. On the 6th of May, 1777, he was admitted a Fellow of the Royal College of Physicians, and in a paper on Nitre, read before the Philosophical Society in 1778, he described, under the name of Vital Air, what is now called Oxygen gas.
On the death of Dr. John Hope in 1786, Rutherford was elected Professor of Botany and Keeper of the Botanical Gardens at Edinburgh, a duty which he discharged until the time of his death, in 1819, at the age of seventy.—Edinburgh Philosophical Journal, vol. 3. May 1820.
