Joseph Black
Cullen taught many students who would go on to influential careers in British science. Indeed, a large number of the doctors who taught in Edinburgh's medical school from the 1790s to 1810s had studied with him, including the chemist Joseph Black, the anatomist Alexander Monro Secundus, and the naturalist John Walker. Cullen's emphasis on the practical benefits of chemistry made his ideas popular amongst farmers, industrialists, naturalists and doctors alike. His influence on these fields was felt through the writings of his students, particularly in the books of John Anderson, the 'Aberdeen Agricola', and the lectures given by Joseph Black and John Walker from the 1770s to 1790s.
