Julius Robert Mayer

Julius Robert Mayer was a German physician and physicist who contributed significantly to the understanding of energy conservation in the 19th century. He is best known for formulating the principle of energy conservation, which later helped lay the groundwork for the laws of thermodynamics. Mayer's work connected heat, work, and energy, and his ideas eventually influenced atomic physics by explaining how energy can be transformed from one form to another at the atomic level. His pioneering insights helped shape modern physics and our understanding of the fundamental nature of energy and matter.
