title: American Diabetes Association
context: The ADA was founded in 1940 by six leading physicians − including Dr. Herman O. Mosenthal, Dr. Joseph T. Beardwood Jr., Dr. Joseph H. Barack, and Dr. E. S. Dillion − at their 1939 meeting of The American College of Physicians[5]. In September 1946, they hosted a meeting in Toronto, Canada to celebrate the twenty-fifth anniversary of the discovery of insulin. The meeting served as a successful forum for hundreds of physicians and leading figures interested in the studies of diabetes and carbohydrate metabolism[5]. The organization is now a national nonprofit with 40 affiliate organizations, more than 800 individual chapters[6], over a million volunteers, and almost 1,000 staff members − including officer and a board of directors[7].
