PHOTO COURTESYPHOTO OF MINNESOTA THE UNIVERSITY American History in Washington D.C. While leading Minnesota figures in cardiac surgery—F. John Lewis, C. Walton Lillehei and Earl Bakken, to name a few— have been honored, much of the credit is also attributed to the singular leadership of department chair Owen Harding Wan- gensteen, who served as the department’s charismatic leader from 1930 to 1967.1 Fostering an atmosphere that emphasized the need for surgical science, he encour- aged surgeons to develop active research agendas in the laboratory. The focus on surgical research and its integration into medical education yielded many impor- tant contributions to mid-century surgery beyond cardiology’s impressive results. Wangensteen presided over an active research program that included the devel- opment of nasogastric suction to manage the surgical complications of bowel ob- struction and Henry Buchwald’s work on cholesterol metabolism and development of bariatric surgery. Moreover, during the Wangensteen era, the stage was set for the pioneering organ transplant work that followed under John Najarian’s tenure as chair during the 1970s. Wangensteen also supported the work of surgeons such as William Bernstein and Stanley Goldberg, Beyond cardiac surgery Owen H.
