World Crohn's and Colitis Day Hero

Burrill B. Crohn

Dr. Burrill B. Crohn (1884–1983) was an American gastroenterologist who, along with Leon Ginzburg and Gordon D. Oppenheimer, published a seminal paper in 1932 describing a new regional ileitis, which later became known as Crohn's disease. His work was crucial in distinguishing this inflammatory bowel disease from other gastrointestinal conditions, significantly advancing medical understanding and diagnosis.

History of World Crohn's and Colitis Day

For many years, Crohn’s disease and ulcerative colitis remained mostly unknown. Wilks and Moxon, two English physicians, were the first to identify ulcerative colitis in 1875, effectively distinguishing it from infectious diarrheal disorders. There were accounts of an illness that had symptoms similar to ulcerative colitis before the Civil War. It wasn’t until 1875 that it was identified as a distinct illness.

In 1956, Suzanne Rosenthal began experiencing terrible gastrointestinal troubles. Doctors had no idea what was wrong with her for years and had even misdiagnosed her. After being moved by Suzanne’s experience, the Rosenthals began exploring methods to fund Crohn’s and colitis research in the 1960s.

The National Foundation for Ileitis and Colitis was created on September 12, 1967, by the Rosenthals, the Models, and Dr. Henry Janowitz to address the issue of Crohn’s and Colitis. It wasn’t until 1932 that three doctors, Burrill Crohn, Leon Ginzberg, and Gordon D. Oppenheimer described Crohn’s disease for the first time. Intestinal Tuberculosis was assumed to be the only disease affecting the small intestine at the time. These doctors gathered information from 14 patients who had abdominal cramps, diarrhea, fever, and weight loss, and discovered that the symptoms were not caused by tuberculosis or any other known illness. They defined a novel disease entity named ‘regional ileitis’ at first, and then Crohn’s disease subsequently. I.B.D. was poorly understood for many years after the two diseases were discovered, and little study was performed into the causes and treatments of Crohn’s and Colitis, let alone a hunt for remedies.
