Editor's Take:

Lord Kelvin was a giant of Victorian science who moved easily between theory and engineering. He helped found thermodynamics and defined absolute zero. He also invented instruments that made long-distance telegraphy work. The success of the Atlantic cable made him rich and famous. He was not always right. His estimate of the Earth's age was far too young, and he doubted some new ideas. Still, his name lives on in the scientific unit of temperature.

  2. 1848: Proposes an absolute temperature scale
