The first systematic treatise on public hygiene. Frank believed the ruler of a state should stand in the relation of a father to his children, among his duties being the safeguarding of the people’s health and the preservation of a healthy race by appropriate laws. The last two volumes were edited by G. C. G. Voigt. Portions were translated into English as A system of complete medical police: Selections from Johann Peter Frank. Edited with an introduction by Erna Lesky. (Baltimore: Johns Hopkins Press, 1976.).
