John Davy FRS (1790-1868) was a British doctor, amateur chemist, and brother of the noted chemist
Sir Humphry Davy, and cousin of Edmund Davy.
John Davy was born in
Penzance, Cornwall. He assisted his older brother Humphry at the Royal Institution of Great Britainfor two years before heading to Edinburgh University, where he earned his degree in medicine in 1814. Davy is perhaps most noted for his discovery of phosgenein 1812, a compound he also named.

Upon graduation, Davy joined the
British Army Medical Departmentand became Inspector General of Hospitals. He used his position to travel to a great number of the English colonies, including India, Ceylon, and Barbados.
In 1834 he was elected a Fellow of the
Royal Society. From 1836 to 1840 he produced nine volumes on the collected works of his brother. After a brief time spent living in the West Indies, Davy returned to England, where he died in 1868.
In 1863 he discovered that eggshells have about 8,000 pores that are large enough for oxygen to flow in and carbon dioxide to flow out by pumping pressurized air into an underwater egg and watching thousands of tiny bubbles appear on the surface of the shell.cite news |last=Mingo |first=Jack |coauthors=Erin Barrett |title=Just Curious, Jeeves |publisher=Emeryville, CA
