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. [3] 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.
In 1876, a collection of McCulloh's lecture notes were published in a book entitled Treatise on the Mechanical Theory of Heat and its Application to the Steam Engine, Etc. McCulloh acknowledged the pioneering work of James Prescott Joule and Nicolas Léonard Sadi Carnot in establishing the laws of thermodynamics. He went on to say of this ...
1840 – James Prescott Joule formulates the equation for Joule heating quantifying the amount of heat produced in a circuit as proportional to the product of the time duration, the resistance, and the square of the current passing through it. [30]
The Gallery planned lectures and demonstrations and the collection of a library was started. [ 1 ] In February 1841, Sturgeon promoted James Prescott Joule 's first public lecture at the Gallery and the directors were sanguine about the Gallery's prospects.
Joule's apparatus for measuring the mechanical equivalent of heat. Most established scientists, such as William Henry, [13] as well as Thomas Thomson, believed that there was enough uncertainty in the caloric theory to allow its adaptation to account for the new results. It had certainly proved robust and adaptable up to that time.

He assisted the physicist James Prescott Joule with the development of scientific instruments such as an apparatus for measuring the internal capacity of the bore of thermometer tubes, a tangent galvanometer, and other devices useful in Joule's research. [5]
1840 – James Prescott Joule formulates Joule's Law (sometimes called the Joule-Lenz law) quantifying the amount of heat produced in a circuit as proportional to the product of the time duration, the resistance, and the square of the current passing through it.
