William Thomson, Lord Kelvin, was born at Belfast on the 26th of June, 1824. His father was a distinguished mathematician, and was Professor of Mathematics, first in Belfast, and afterwards in Glasgow University. At a very early age, Lord Kelvin showed extraordinary mathematical ability; and he passed with great distinction, first through the University of Glasgow, and then through Cambridge, where he gained the Second Wranglership and the first Smith's Prize. He became Professor of Natural Philosophy in the University of Glasgow in 1846, at the age of twenty-two; and he still holds that office. He was one of the pioneer band who laid the first successful Atlantic cable, in 1858. In 1866 Her Majesty conferred the honour of knighthood on him for his distinguished services to the science and practice of submarine telegraphy. Lord Kelvin is the author of many inventions. His mariner's compass and sounding machine have done good service to seamen. His electrical instruments are the standards all over the world. He is President of the Royal Society and member of every important scientific society at home and abroad. In January, 1892, the Queen conferred upon him his peerage. He held the Colquhoun Sculls, at Cambridge, for two years. He is a sailor at heart and an enthusiastic yachtsman; and, among amateurs, a more keen lover of music it would be difficult to find.
