Daniel Rutherford

Daniel Rutherford FRSE FRCPE FLS FSA(Scot) (3 November 1749 – 15 November 1819) was a British physician, chemist, and botanist. He made an important discovery in the field of chemistry. In 1772, he isolated the gas we now call nitrogen. This was a key moment in understanding the makeup of air and how gases work.

Rutherford was also interested in many other areas of science. Besides his work with gases, he studied plants and their uses, which helped advance the field of botany. His contributions to science helped later researchers learn more about the world around us.

Because of his many achievements, Rutherford was recognized by several important scientific groups during his lifetime. His work remains a important part of the history of chemistry and science.

Life

Daniel Rutherford was born on 3 November 1749. He studied medicine at the University of Edinburgh and became a doctor in 1772. Later, he taught botany there and helped start important groups like the Harveian Society of Edinburgh and the Royal Society of Edinburgh.

Rutherford also worked as a doctor in Edinburgh and lived in a house on the Royal Mile. He taught many students and was known for his work with plants. He passed away suddenly in Edinburgh on 15 November 1819.

Family

Daniel Rutherford had an interesting family connection. He was the uncle of the famous novelist Sir Walter Scott. In 1786, he married Harriet Mitchelson, who came from a place called Middleton.

Isolation of nitrogen

Daniel Rutherford discovered nitrogen in 1772 by isolating the gas. He studied this after his teacher, Joseph Black, noticed that a candle would not burn in carbon dioxide. Rutherford conducted an experiment where he placed a mouse in a confined space with air until the mouse could no longer survive. He then burned a candle and phosphorus in the remaining air until they stopped burning. After passing the air through a solution that absorbed carbon dioxide, the leftover gas did not support combustion and could not sustain life.

Rutherford named this gas “noxious air” or “phlogisticated air.” He shared his findings in 1772. At the time, he and Joseph Black believed in the phlogiston theory, which was the common explanation for combustion back then.
