'''James Prescott Joule''' (1818 - 1889) was a [[Beer | brewer]] who, due to his work studying heat<ref>[http://scienceworld.wolfram.com/biography/Joule.html Wolfram.com Joule biography]</ref>, became one of the founders of the science of [[thermodynamics]]. He is best known for showing that mechanical work and heat are interchangeable, which he did by carefully measuring the tempearature increase in water stirred by paddle wheels.

The SI Unit of energy, the [[Joule]], is named in his honor.
