Herman von Helmholtz (31 ago 1821 ano – 8 set 1894 ano)

Descrição:

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.
