William Thomson

Sir William Thomson, 1st Baron Kelvin (June 26, 1824-December 17 1907) was a physicist and engineer who made important contributions to the mathematical analysis of both electricity and thermodynamics. In honor of his work, absolute temperature is stated in units of kelvin. But his contributions were not limited to physics; he was instrumental in completing the transatlantic telegraph and made advancements in the reliability of the mariner's compass.
