Benjamin Thompson (Count Rumford)

Benjamin Thompson, known as Count Rumford, was an American-born physicist and inventor in the 18th century who made important contributions to our understanding of heat and energy. He challenged the idea that heat was a form of material substance (caloric theory) and demonstrated that heat is generated through motion, such as friction. His experiments helped establish the idea that heat arises from mechanical work. Rumford also invented practical devices like improved cannons and restaurant coffee percolators, showcasing his innovative engineering skills. His work laid foundational principles for thermodynamics, influencing how scientists understand energy transfer.
