The aim of this paper is to describe the life and work of the homeopathic lay physician Arthur Lutze (1813-1870), particularly his work in Prussia. The paper also helps explain the extraordinary popularity of non-medical practitioners during this period. Lutze's years in Prussia were fundamental for his homeopathic ambitions, since they afforded him access to many of the renowned homeopaths of the period. Lutze gained popularity by focusing his practice on the common people. Even though he was not licensed and he collaborated with unknown non-medical practitioners, Lutze gained legitimacy through the work of properly certified doctors.
