[The Membership List of the Tokyo Society of Anesthesiologists (April 1959) and a Group Photograph of the First General Meeting of the Society.].

A leaf titled "The Membership List of the Tokyo Society of Anesthesiologists (April 1959)" was donated in 2015 from Hisayo 0. Morishima, an Emeritus pro- fessor of Columbia University, to the Japanese Museum of Anesthesiology. It measures 26 cm long and 36 cm across. The list is mimeographed on the reverse of "The Prospectus of the Foundation of the Tokyo Soci- ety of Anesthesiologists" issued in January 1959. It contains 23 members and an additional member is written by hand at the bottom. This document is important in the history of the society because it describes that the society's initial membership was 23 and indicates that the society was formally organized by April 1959. The society contributed toward the governmental approval of anesthesiology as a"Specially approved specialty" in 1960.
