James Joule was born in 1818, the son of Benjamin Joule (1784–1858), a wealthy brewer, and his wife, Alice Prescott, on New Bailey Street in Salford. Joule was tutored as a young man by the famous scientist John Dalton and was strongly influenced by chemist William Henry and Manchester engineers Peter Ewart and Eaton Hodgkinson .
James Prescott Joule, English physicist who established that the various forms of energy, such as electrical and heat, are basically the same and can be changed one into another. Thus, he formed the basis of conservation of energy, the first law of thermodynamics.

Learn about the life and achievements of James Prescott Joule, a British scientist who studied heat, work and energy. He discovered the mechanical equivalent of heat, formulated Joule's law and the Joule-Thomson effect, and received the Copley Medal.
May 21, 2018 · The English physicist James Prescott Joule (1818-1889) proved that mechanical and thermal energies are interconvertible on a fixed basis, and thus he established the great principle of conservation of energy.
James Prescott Joule (1818–89) is now rightly revered as one of the greatest scientists in the history of physics, due to his groundbreaking work in thermodynamics. However, this was not always the case—in his younger years, Joule struggled to be taken seriously by the scientific establishment.
Learn about James Joule, a pioneer of thermodynamics who developed the mechanical theory of heat and Joule's law. Discover his life, achievements, challenges and legacy in this comprehensive biography.
James Prescott Joule was an English physicist who studied the nature of heat and discovered its relationship to mechanical work. This study later led to formation of the first law of thermodynamics.
