    The limelight effect was discovered in the 1820s by Goldsworthy Gurney, [3] [4] based on his work with the "oxy-hydrogen blowpipe", credit for which is normally given to Robert Hare. In 1825, a Scottish engineer, Thomas Drummond (1797–1840), saw a demonstration of the effect by Michael Faraday [ 5 ] and realized that the light would be useful ...
