American Medical Association
In 1847 after a report by physician Nathan Smith Davis, sometimes called the "father of the AMA", American physicians met in Philadelphia and formed the AMA as a national professional medical organization, the first of its kind in the world, going on to establish uniform standards for medical education, training, and practice, the world's first national code for ethical medical practice. Ever since, the AMA Code of Medical Ethics dictates professional conduct for practicing physicians.
