In the 1820s, British Army officer Thomas Drummond used this property of lime to develop a light that could be used in lighthouses and on the battlefield. Called Drummond lights, they eventually replaced the gas lights used in music halls and theatres. Performers and actors were now ‘in the limelight’ when on stage.
