While various names were considered for the scientific group to become a Scientific Society (such as AIDA, which stood for 'Association for the Improvement of the Dosing of Anti-infectives, or OTELLO, which was for 'Organization for Terminating and Eliminating all Little Living Organisms', all denominations obviously denoting the interest of the Fouding Members for Opera in addition to pharmacodynamics), a decision for International Society for Anti-infective Pharmacology (ISAP), to stress upon the importance of Pharmacology as the basic science on which our activities needed to rely, was eventually reached at a meeting held in Atlanta, GA in the fall 1990.

The Society was created in July 1991 in Berlin, Germany, after having organized its first scientific meeting as an official symposium of the 1991 ICC (International Conference on Chemotherapy). It was later (1993) incorporated as a scientific organization under the laws of the State of South Australia, Australia (mainly because the secretary was from Australia...).  Later on, the chart of the Society was moved to the State of California, United States of America, where the Society is now incorporated.  

Over the years, the Society has made several meetings and symposia which are described in the section "Past Meetings".
