Kelvin (1824-1907) was born William Thomson and educated at Glasgow and Cambridge. He was profesor of Natural Philosophy (Physics) at the University of Glasgow for 53 years. Kelvin was a pioneer of thermodynamics and electromagnetic theory. 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. Kelvin and his wife are shown here in coronation dres, when he was made Lord Kelvin on New Years Day 1892.
