DRUMMOND, THOMAS (r797-1840)

This article appears in Volume V08, Page 600 of the Encyclopedia Britannica.

Encyclopedia Britannica - Main :: DRO-ECG
DRUMMOND, THOMAS (r797-1840) , British inventor and
administrator
 , was born at Edinburgh on the loth of. October 1797, and was educated at the high school there. He was appointed to a cadetship at the Royal Military
Academy
 , Woolwich, in 1813; and in 1815 he entered the Royal Engineers. In 1819, when meditating the renunciation of military service for the bar, he made the acquaintance of Colonel T. F. Colby (1784-1852), from whom in the following year he received an appointment on the trigonometrical survey of
Great
  Britain. During his winters in London he attended the chemical lectures of W. T. Brande and M. Faraday at the Royal Institution, and the mention at one of these of the brilliant luminosity of lime when incandescent suggested to him the employment of the lime light for making distant surveying stations visible. In 1825, when he was assisting Colby in the Irish survey, his lime-light apparatus (" Drummond light ") was put to a
practical
  test, and enabled observations to be completed between Divis
mountain
 , near Belfast, and Slieve Snaght, a distance of 67 m. About the same time he also devised an improved
heliostat
 , and in 1829 he was employed in adopting his light for lighthouse purposes. In 1831 he entered political life and was appointed superintendent of the boundary commission. Four years later he was made under-secretary of state for Ireland, where he proved himself a most successful
administrator
 , and did much to promote law and order. It was he who in 1838 told the Irish landlords that " property has its duties as well as its rights." In 1836 he proposed the appointment of a commission on rail-ways in Ireland, and took a Iarge share in its
work
 , which resulted in the recommendation, not, however, carried out, that the state should construct a
system
  of lines throughout the
island
 . Drummond's
health
  was undermined by overwork, and he died at Dublin on the 15th of April 1840.
