Thomas Drummond

Life & Legacy

Captain Thomas Drummond (10 October 1797 – 15 April 1840), from Edinburgh was a Scottish British Army officer, civil engineer and senior public official. He used the Drummond light which was employed in the trigonometrical survey of Great Britain and Ireland. He is sometimes mistakenly given credit for the invention of limelight, at the expense of Sir Goldsworthy Gurney. It was Drummond, however, who realised its value in surveying.
