William Thomson, Lord Kelvin,  1824-1907

Born in Belfast. He held the chair of Natural Philosophy at Glasgow from 1846-1903. He discovered the second law of thermodynamics. His work on electrical currents ensured the successful laying of the Atlantic cables. He invented many useful marine devices including tide gauges, predictors, depth sounding equipment and developed a new marine compass. His name lives on in the standard measure of temperature on the scale named after him. There is a statue of him at the entrance to the Botanic Gardens in Belfast. He is buried in London.
