Kelvin, 1st Baron - William Thomson [Astro*Index]

William Thomson - 1st Baron of Kelvin

(26 June 1824 – 17 December 1907) Belfast.

Professor of Natural Philosophy at the University of Glasgow for 53 years, 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.

Absolute temperatures are stated in units of kelvin in his honour. While the existence of a lower limit to temperature (absolute zero) was known prior to his work, Kelvin is known for determining its correct value as approximately −273.15° Celsius or −459.67° Fahrenheit. The Joule–Thomson effect is also named in his honour.
