The American Medical Association (AMA), founded in 1847 and incorporated in 1897, is the largest association of physiciansâboth MDs and DOs âand medical students in the United States.
In 1975, the organization changed its name to the American Medical Student Association (AMSA), in order to clarify its separation from the AMA. It also saw the election of the first woman president.
