Humphry Davy, British chemist, 19th century
Humphry Davy, British chemist, 19th century. Born in Penzance, Cornwall, Davy (1778-1829) discovered the anaesthetic effects of laughing gas (nitrous oxide). In 1801 he was appointed lecturer at the Royal Institution, where he investigated, with his assistant Michael Faraday (1791-1867), his theory of volcanic action. Using electrolysis, Davy isolated the metals barium, calcium, magnesium, potassium, sodium and strontium, as well as proving that chlorine was a chemical element. He is probably best known for his invention in 1815 of the miners safety lamp, which enabled deeper, more gaseous seams to be mined without risk of explosion. Engraving after a portrait by James Lonsdale (1777-1839)

EDITORS COMMENTS
This print showcases Humphry Davy, a renowned British chemist of the 19th century. Born in Penzance, Cornwall, Davy made significant contributions to various fields of science and medicine. One of his notable discoveries was the anaesthetic effects of laughing gas or nitrous oxide. As a lecturer at the Royal Institution from 1801 onwards, he collaborated with his assistant Michael Faraday to study volcanic action using electrolysis. Davy's groundbreaking experiments led him to isolate several metals like barium, calcium, magnesium, potassium, sodium, and strontium. Additionally, he proved that chlorine was indeed a chemical element through his meticulous research. However, perhaps Davy's most famous invention came in 1815 when he created the miners' safety lamp. This ingenious device allowed miners to work safely in deeper and more gaseous seams without fearing explosions. The accompanying engraving is based on a portrait by James Lonsdale (1777-1839), capturing the essence of this brilliant scientist. The monochrome black and white aesthetic adds an air of authenticity to this historical image. Humphry Davy's legacy as an inventor and chemist continues to inspire generations even today. His contributions have undoubtedly shaped our understanding of chemistry and its applications across various industries such as mining and medicine.
