In a lecture on "Electrical Units of Measurement" (1883) and published in "Popular Lectures Vol. I.". William Thomson (1824–1907) was an Irish-born British mathematical physicist and engineer. 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.
