Joseph Black, a British chemist and physicist, is famous for his discovery of carbon dioxide. Black was always a meticulous chemist, keeping careful note of all his results and measurements. It was this which led to his discovery of carbon dioxide.
Black also took an interest in the science of heat. In the 18th century, there were several competing theories about the nature of heat, and how it related to temperature.
Black’s investigations not only clarified the distinction between temperature and heat, but also resulted in the theory of latent heat. Black was gifted and effective teacher. His course in chemistry proved so popular that many students, even those with no particular interest in the subject, were eager to attend.
Alongside his teaching, black carried on an active and demanding medical practice. Joseph Black, widely respected both as a scientist and a physician, is truly one of the titans in the world of science.
