The three met in Rochester, Minnesota, at which time Dr. Waugh confessed that he had been entertaining similar thoughts for a society devoted to the advancement of alimentary surgery. The Society was incorporated on March 30, 1960, and was initially named the Association for Colon Surgery. The founding membership consisted of authors who had contributed papers to six issues of the Surgical Clinics of North America edited by Dr. Turell and the authors of the chapters in his textbook Diseases of the Colon and Anorectum. In Dr. Robert Turell the beginning it was thought advisable to limit the Society’s interest to surgery of the colon, but Dr. Cole proposed that the name be changed to The Society for Surgery of the Alimentary Tract to reflect wide interest in abdominal surgery. Dr. Robert Zollinger, the Society’s third president, gave a convincing address entitled “Justifying our Existence.”2 He noted that papers related to the alimentary tract made up less than half of the programs of other societies including the American College of Surgeons Clinical Congress, and that SSAT was the only North American organization focused on surgical problems of the entire alimentary tract, a situation which still exists Dr. John Waugh today. 6 SSAT.book Page 7 Friday, April 21, 2006 12:58 PM 47TH ANNUAL MEETING • MAY 20-24, 2006 • LOS ANGELES, CA The requirements for membership in the Society have been a matter INFORMATION of frequent debate since its inception. In 1965, five years after the GENERAL founding of the society, the Board of Trustees directed that the membership should be enlarged rather than restricted to a small group. The first constitution of the Society was approved that same year. The requirements for membership were: 1. Fellowship in the American College of Surgeons or its equivalent; and 2. Demonstrated interest in the function and disease of the alimentary tract as evidenced by fundamental research or by publication of significant papers. Initially, the number of published papers was flexible, but by 1981, sixteen years later, the requirement for at least 10 publications became the law of the membership committee. As a result, the society’s growth flattened. In 1984, the Board of Trustees became
