He went on to Paris,where he met Gay-Lussac and Cuvier,before becoming Professor at Giessen at the age of 21. He established laboratory-based teaching,and was a gifted if harsh lecturer. His research demonstrated that organic chemistry could be analysed and replicated in the laboratory. He showed that nitrogen-based compounds were essential to plant growth,and invented the first nitrogen fertilisers. His Law of the Minimum stated that plants each have a mineral that regulates their development. With Giebert he devised a method for creating a beef extract from carcasses as a dietary supplement,the bouillon cubes of which were later trademarked as 'Oxo' | |
