[Carl von Bönninghausen--a forgotten homoeopath and his studies]

A lot of physicians practised homoeopathy and dedicated their lives to the method of Samuel Hahnemann, but most of them seem to have been forgotten. By tracing the life of one of them it can be shown how one can learn more about those people and find documents that shed some light on their lives and actions. Carl von Bönninghausen was the son of the famous lay homoeopath Clemens Maria Franz von Bönninghausen. Due to the fact that he married the adoptive daughter of Mélanie Hahnemann some aspects of his life were already known. But he himself had never been the focus of research. Firstly, his life is described with the help of newly found documents. Secondly, notices accidentally found in patient journals show how Carl started as a homoeopath.
