The Flance-Karl Award was established in 1996 by Samuel A. Wells, Jr., M.D., who was then President of the Association. The primary endowment for the award was a gift from Mr. David Farrell, Chief Executive Officer of the May Corporation, and the Barnes-Jewish-Christian Health Care System, both of St. Louis, Missouri. The award recognized I. Jerome Flance, M.D., and Michael M. Karl, M.D., two physicians in St. Louis, who cared for Mr. Farrell and his family. The Flance-Karl Award is presented to a surgeon in the United States of America who has made a seminal contribution in basic laboratory research which has application to clinical surgery. The recipient should be active in clinical or laboratory research and preferably is less than 60 years of age. Prior recipients of the Association’s Medallion for Scientific Achievement are not eligible for the Flance-Karl Award.
