Herman von Helmholtz (31 agos 1821 año – 8 sept 1894 año)

Descripción:

Hermann Helmholtz in 1847 published what is considered a definitive declaration of the conservation of energy. Helmholtz had learned from reading Joule's publications, though Helmholtz eventually came around to crediting both Joule and von Mayer for priority.
