Edmund Davy

Edmund Davy FRS (1785 – 5 November 1857) was a professor of Chemistry at the Royal Cork Institution from 1813 and professor of chemistry at the Royal Dublin Society from 1826. He discovered acetylene, as it was later named by Marcellin Berthelot. He was also an original member of the Chemical Society, and a member of the Royal Irish Academy.

Edmund Davy was a cousin of Humphry Davy, the famous chemist who invented the Davy lamp for the safety of miners.

Edmund, the son of William Davy, was born in Penzance, Cornwall, and lived there throughout his teen years. He moved to London in 1804 to spend eight years as operator and assistant to Humphry Davy in the Royal Institution laboratory, which he kept in order. For a large part of that time, Edmund was also superintendent of the Royal Society's mineralogical collection. When, in October 1807, Humphry accomplished the electrolytic preparation of potassium and saw the minute globules of the quicksilver-like metal burst through the crust and take fire, Edmund described that his cousin was so delighted with this achievement that he danced about the room in ecstasy.

Humphry Davy's younger brother, Dr. John Davy, (24 May 1790 - 24 Jan 1868) also was a chemist who spent some time (1808–1811) assisting Humphry in his chemistry research at the Royal Institution. John was the first to prepare and name phosgene gas.

Edmund William Davy (born in 1826), son of Edmund Davy, became professor of medicine in the Royal College, Dublin, in 1870. That they cooperated in research is shown in a notice to the Royal Irish Academy on the manufacture of sulphuric acid which Edmund Davy ends with an acknowledgement of the assistance he received in his experiments given by his son, Edmund William Davy.
