  • 1814: Physician and physicist Julius Robert von Mayer born. He will describe the vital chemical process now referred to as oxidation as the primary source of energy for any living creature; but his achievements will be overlooked and priority for the discovery of the mechanical equivalent of heat will be attributed to James Joule.
