Walther Hermann Nernst. Walther Hermann Nernst.

Walther Hermann Nernst (1864-1941), a German chemist who applied the principles of thermodynamics to the electric cell. He constructed the Nernst Equation, which related the voltage of a cell to the cell's properties. Nernst was awarded the 1920 Nobel Prize in Chemistry for his discovery of the Third Law of Thermodynamics, which states that entropy approaches a minimum (which can be arbitrarily set to zero) as temperature approaches absolute zero. Nernst invented an electric metallic-filament lamp, a link between the carbon lamp and the incandescent lamp, in 1898.
