William Ramsay/The Gases of the Atmosphere 1896

Rutherford was a Scottish chemist who discovered and isolatednitrogen gas. He kept a mouse in a container of air until it died, burned a candle until it was extinguished and finally burned phosphorus until it would not burn anymore. He passed the remaining gas through an alkaline solution to remove any carbon dioxide. Rutherford called the remaining gas "noxious air" or “phlogisticated air” because it would not support life or combustion.
