William Thomson, 1st Baron Kelvin (1824 - 1907)
William Thomson, 1st Baron Kelvin (26 June 1824 – 17 December 1907), was an Irish and British mathematical physicist and engineer who was born in Belfast in 1824. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its modern form. Lord Kelvin is widely known for determining the correct value of absolute zero as approximately −273.15 Celsius. Absolute temperatures are stated in units of kelvin in his honour.
