[Anesthesia Conference and Anesthesia Colloquium -Michinosuke Amano and the Origin of the Tokyo Society of Anesthesiologists.].

In October 1958, seven anesthesiologists from Tokyo area, who had frequently met at the Anesthesia Collo- quium, discussed founding a society of anesthesiologists to improve their social status. Next month, the Tokyo Society of Anesthesiologists was founded. The society was active in campaigning for the governmental approval of anesthesiology as a specially designated specialty. The colloquium was advocated by Michino- suke Amano of Keio University and was established in March 1955. Thus, the colloquium is considered the starting point of the society. Further, the origin of the colloquium dates back to the Anesthesia Conference held at the suggestion of Professor Wasaburo Maeda of Keio University. The first Anesthesia Conference was held in July 1952 immediately after Amano's return from the United States to Japan.
