Oil painting by Alexander Craig after a chalk drawing by S Laurence of Baron Justus Von Liebig (1803-1873), German chemist and pioneer in the training of chemists and in agricultural chemistry. Von Liebig was one of the most illustrious chemists of his age; he was the founder of agricultural chemistry, a discoverer of chloroform and chloral and, with Friedrich Wohler (1800-1882), of the benzoyl radical. He vastly extended the method of organic analysis, and invented appliances for analysis by combustion and also Liebig's condenser.
