When Was Caloric Theory Abandoned?

A former theory concerning the nature of heat, which was regarded as a weightless fluid (called caloric). It was unable to account for the fact that friction could produce an unlimited quantity of heat and it was abandoned when Joule showed that heat is a form of energy.

Who disproved the caloric theory?

The American-born British physicist Benjamin Thompson, Count Rumford (1753-1814), is best known for his attacks on the caloric theory of heat. Benjamin Thompson was born on March 26, 1753, in Woburn, Mass. He received only 2 years of formal education and at 13 was apprenticed to a local merchant.

Did James Joule believe in the caloric theory?

Joule decided the caloric theory was suspect. ... He was fully familiar with Carnot's work, and believed the caloric theory to be correct. But he knew that if Joule really had produced heat by stirring water, the caloric theory must be wrong—he said there were "insuperable difficulties" in reconciling the two.
