William Reid Clanny
William Reid Clanny (1770 – 10 January 1850) was an Irish physician and inventor of a safety lamp.
He was born in Bangor, County Down, Ireland. He trained as a physician at Edinburgh, and served as an assistant surgeon in the Royal Navy. He was present at the Battle of Copenhagen in 1801. He left the Navy and graduated in 1803 before settling for a while in Durham. He moved to Bishopwearmouth, near Sunderland, England and practised there for 45 years.
Clanny died on 10 January 1850 and was buried at Gill Cemetery in Sunderland. The entry in the Dictionary of National Biography states "his claim to remembrance rests on his efforts to diminish the loss of life from explosions in collieries.
In the same year Clanny completed his first lamp consisting of a candle in a glass surround. Below the glass was a trough containing water through which air was forced by a pair of bellows. Fumes bubbled out through another water chamber above. A paper 'On the Means of procuring a Steady Light in Coal Mines without the Danger of Explosion' was read before the Royal Society on 20 May the following year.
Early machines were quite cumbersome. But Clanny later succeeded in reducing the weight of the lamp to 34 ounces.
By 1816, when Clanny published Practical observations on safety lamps for coal mines, he had experimented in person with a safety lamp at the Mill Pit in Herrington near Sunderland,[a] where there had been a serious explosive accident, with the loss of 24 lives, on 10 October 1812. Clanny won medals in 1816–17 for his invention from the Royal Society of Arts.
His lamp and other improvements were, after some initial disputes, recognised for their true worth by his contemporaries, including northern coal owners who presented him with a purse of gold. with a silver salver at the Athenæum, Sunderland, on 3 February 1848.
