Surprised this isn't higher up. Crohn's was formally named/created as its own clinical entity in 1932 and the paper shows one of its graphs (Fig 1) starting in the 1940s. I doubt 8 years was enough for awareness to get out to the entire physician community about the existence of the disease and there were probably a lot of misdiagnosed cases in its early days (since crohn's has a clinically diverse presentation).
