The history of organized anesthesiology in Indiana precedes the ISA with the founding of the Committee on Anesthesia and later the Section of Anesthesia of the Indiana State Medical Association (ISMA). As early as 1926, the ISMA had a Committee on Anesthesia. The Section on Anesthesia became the fourth Section of the ISMA largely through the leadership of Floyd Romberger, M.D. of Lafayette.
