Forty-four Nobel laureates in Chemistry are scientific heirs of Liebig. Liebig was one of the first chemists to organize a laboratory as we know it today. He improved organic and inorganic analysis of compounds. With Friedrich Wöhler, he developed a theory of radicals and made the first experimental discovery of isomerism. Liebig wrote books about agricultural and animal chemistry where there was a practical application of organic chemistry to animal and plant science. L...
