hiphotos043767 William Thomson, Lord Kelvin, Irish-Scottish mathematician, physicist and engineer, (20th century). Kelvin (1824-1907) was a leader in the physical sciences of the 19th century. He did important work in the mathematical analysis of electricity and thermodynamics, and did much to unify the various theories of heat held by leading scientists of the time. Kelvin introduced the Kelvin or absolute scale of temperature, and discovered the Thomson effect in thermoelectricity. Also significant are his discoveries and improvements in the field of communication via submarine cables, and his invention of the reflecting galvanometer and the siphon recorder.//

hiphotos009880 William Edward Ayrton (1847-1908), British physicist, electrical engineer and inventor, 1892. Ayrton studied under Lord Kelvin at Glasgow. In 1873 he was appointed to the first chair in natural philosophy and telegraphy at Imperial Engineering College, Tokyo, and was appointed professor of electrical engineering at the Central Technical College, South Kensington in 1884. Ayrton was the first to advocate power transmission at high voltage, and in collaboration with John Perry he invented electrical measuring instruments including the spiral-spring ammeter and the wattmeter. The ammeter (ampere meter) was one of the first to measure current and voltage reliably. Ayrton and Perry also worked on railway electrification, produced a dynamometer and developed the first electric tricycle. Ayrton worked on the electric searchlight with his second wife Phoebe Marks, who later became famous for her work on the electric arc.//

hiphotos014650 Lord Kelvin, Scottish mathematician and physicist, 1876. Born William Thomson, Lord Kelvin (1824-1907) was educated at Glasgow and Cambridge. He was Professor of Natural Philosophy (Physics) at the University of Glasgow for 53 years. Kelvin was a pioneer of thermodynamics and electromagnetic theory and devised the temperature scale that bears his name. He also directed work on the first transatlantic cable telegraph, which gave him considerable wealth. He was probably the first scientist to become wealthy through his work.//

He turned to improving his compass comparitively late in life. It had a very light card giving a long period of oscillation. The compass was mounted in a binnacle fitted with magnets and spheres and was much more accurate than previous compasses.//
