James Tyler Kent
James Tyler Kent (1849–1916) was an American physician. Prior to his involvement with homeopathy, Kent had practiced conventional medicine in St. Louis, Missouri. He discovered and "converted" to homeopathy as a result of his wife's recovery from a serious ailment using homeopathic methods.
In 1881, Kent accepted a position as professor of anatomy at the Homeopathic College of Missouri, an institution with which he remained affiliated until 1888. In 1890, Kent moved to Pennsylvania to take a position as Dean of Professors at the Post-Graduate Homeopathic Medical School of Philadelphia. In 1897 Kent published his magnum opus, Repertory of the Homœopathic Materia Medica. Kent moved to Chicago in 1903, where he taught at Hahnemann Medical College.
