Born in Belfast,he moved with his family to [Glasgow]] in 1831 when his father accepted a position at the university of Glasgow as a professor of mathematics. Thomson would, in turn, become a professor of natural philosophy (physics) at the same university. In addition to his pioneering work in the field of thermodynamics, Thomson was a major contributor to the laying of the first transatlantic telegraph cable.
