Drummond, Thomas

    0.06 sec.

Drummond, Thomas (1797-1840)

Scottish engineer and administrator. He was the inventor of the powerful ‘Drummond light’, widely used in lighthouses and in the theatre, where it became known as ‘limelight’.

Born in Edinburgh, Drummond entered the Royal Engineers in 1815. The ‘Drummond light’, which he invented in 1825, worked by heating a block of lime to incandescence in an oxy-hydrogen flame. He was appointed Under-Secretary for Ireland in 1835.
