Samuel Hahnemann was the founder of Homoeopathy. He established the fundamental principles of the science and art of Homoeopathy. He is called the Father of Experimental Pharmacology because he was the first physician to prepare medicines in a specialized way; proving them on healthy human beings, to determine how the medicines acted to cure diseases. Before Hahnemann, medicines were given on speculative indications, mainly on the basis of authority without experimental verification. Hahnemann discovered the remedial powers of drugs and inert substances such as gold, platinum, silica, vegetable charcoal, lycopodium, etc.
