A leading authority on Crohn’s disease and ulcerative colitis, he pioneered and perfected surgical techniques to correct various colorectal diseases. Dr. Turnbull and Norma Gill, RN (a former patient of his), founded the first school for the care and treatment of patients with external stomas. Grateful residents and fellows who trained under Dr. Turnbull formed the Rupert Turnbull Surgical Society in 1976.    ## Explore the Decades ### [![Polaroid of forest](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/Origins/War%20Story/Centennial-WarStory-SmallThumbnail.jpg?width=242&height=214&name=Centennial-WarStory-SmallThumbnail.jpg) Origins](https://magazine.clevelandclinic.org/2021-centennial/origins?hsLang=en) ### [![Cleveland Clinic Building](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1920s/Decade%20Page/1920-Small.jpg?width=242&height=214&name=1920-Small.jpg) The 1920s](https://magazine.clevelandclinic.org/2021-centennial/1920s?hsLang=en) ### [![Clinic Building](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1930s/Decade%20Page/1930-Small.jpg?width=242&height=214&name=1930-Small.jpg) The 1930s](https://magazine.clevelandclinic.org/2021-centennial/1930s?hsLang=en) ### [![George Crile Sr.](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1940s/Decade%20Page/1940-Small.jpg?width=242&height=214&name=1940-Small.jpg) The 1940s](https://magazine.clevelandclinic.org/2021-centennial/1940s?hsLang=en) ### [![Willem Kolff, MD, PhD, holding a can](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1950s/Decade%20Page/1950-Small.jpg?width=242&height=214&name=1950-Small.jpg) The 1950s](https://magazine.clevelandclinic.org/2021-centennial/1950s?hsLang=en) ### [![Dr. Rupert Turnball, MD with 3 women](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1960s/Decade%20Page/1960-Small.jpg?width=242&height=214&name=1960-Small.jpg) The 1960s](https://magazine.clevelandclinic.org/2021-centennial/1960s?hsLang=en) ### [![Floyd Loop, MD](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1970s/Decade%20Page/1970-Small.jpg?width=242&height=214&name=1970-Small.jpg) The 1970s](https://magazine.clevelandclinic.org/2021-centennial/1970s?hsLang=en) ### [![Joseph Hahn, MD operating on a patient](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1980s/Decade%20Page/1980-Small.jpg?width=242&height=214&name=1980-Small.jpg) The 1980s](https://magazine.clevelandclinic.org/2021-centennial/1980s?hsLang=en) ### [![Sherwin building](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/1990s/Decade%20Page/1990-Small.jpg?width=242&height=214&name=1990-Small.jpg) The 1990s](https://magazine.clevelandclinic.org/2021-centennial/1990s?hsLang=en) ### [![Taussig Cancer Institute](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/2000s/Decade/2000-Small.jpg?width=242&height=214&name=2000-Small.jpg) The 2000s](https://magazine.clevelandclinic.org/2021-centennial/2000s?hsLang=en) ### [![Stewart Kohl and Larry Pollock](https://magazine.clevelandclinic.org/hs-fs/hubfs/CC%20Magazine/Centennial/2010s/Decade%20Page/2010-Small.jpg?width=242&height=214&name=2010-Small.jpg) The 2010s](https://magazine.clevelandclinic.org/2021-centennial/2010s?hsLang=en) ### [![Lara K.
