Johan Wallerius, founder of agricultural chemistry
Swedish chemist and mineralogist Johan Gottschalk Wallerius was born on 11 July 1709.
Wallerius is considered the founder of agricultural chemistry. His 1761 work Agriculturae fundamenta chemical, a thesis on the role of chemistry in the development of agriculture, established the idea that the chemical composition of both the plants and the soil were to be comparatively studied.
Gottschalk studied mathematics, physics and medicine, and after graduating established a course in chemistry that allowed students in pharmacy and chemistry to witness demonstrations and practice themselves with the experiments.
