Dr. Adolph Frederick Erdmann (1867-1953) founded the Long Island Society of Anesthetists in 1905. The first meeting was attended by eight physicians. This was the first professional anesthesia society in the United States, and the second in the world. It steadily grew to become a statewide, and then a nationwide organization. In 1944, it was renamed The American Society of Anesthesiologists
(ASA). Dr. Erdmann was made ASA's Member No. 1, and he was given this silver membership certificate in honor of the occasion. At that time, ASA had over 1,000 members. As of December, 2013 the ASA had over 52,000 members.
