History

The American College of Physicians (ACP) is a national organization of internists – specialists who apply scientific knowledge and clinical expertise to the diagnosis, treatment, and compassionate care of adults across the spectrum from health to complex illness. The ACP mission is to enhance the quality and effectiveness of health care by fostering excellence and professionalism in the practice of medicine. ACP was founded in 1915 to promote the science and practice of medicine, and since 1915 has supported internists in their quest for excellence. By sharing the most updated medical knowledge, offering top-notch educational resources, and a wide array of additional benefits, ACP has shown a commitment to internal medicine and those who practice it.

Much has transpired in internal medicine and in healthcare over the last 100 years. ACP has changed as well and stands proudly as the largest medical specialty organization in the United States and a major voice in American health care. ACP’s membership of 143,000 includes internists, internal medicine subspecialists, medical students, residents, and fellows, and a growing international presence. As ACP celebrates its centennial, the first 100 years of the College provide an inspiration for us all as ACP applies the rigorous scientific standards of internal medicine as the foundation for meeting the challenges ahead and for best serving our physicians and their patients.
