William Reid Clanny FRSE (1776 – 10 January 1850) was an Irish physician and inventor of a safety lamp.
Clanny was born in Bangor, County Down, Northern 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.
He was elected a Fellow of the Royal Society of Edinburgh in 1825, his proposers being Sir George Ballingall, Robert Kaye Greville, and Sir William Newbigging.
Clanny died on 10 January 1850 and was buried at Galleys 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 1812 the Felling mine disaster and later in the year the explosion at Mill Pit in Herrington near Sunderland concentrated minds on the problems of underground lighting.
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.
