Dr. James Tyler Kent was an American physician who converted to homeopathy in 1878 after his wife Lucy made a dramatic recovery using homeopathic treatment. He went on to become a leading advocate for high potency homeopathy in the United States. Kent made major contributions including developing a comprehensive repertory, proving many new remedies, and emphasizing the use of single remedies in high potencies based on the totality of a patient's physical and mental symptoms. His interpretation of homeopathic philosophy has greatly influenced practice around the world.
