Informed consent in human experimentation before the Nuremberg code

Abstract
The introduction of scientific and experimental methodology into clinical medicine in the nineteenth century brought with it an increased demand for experimentation on human subjects, particularly in bacteriology, immunology, and physiology. This research was done mainly on patients in hospital, often without their consent, under an “ethos of science and medical progress.” As a result of injury to some patients subjected to non-therapeutic research, however, controversy and public debate ensued about the ethics of human experimentation.1 2 3 4
