That’s Burrill B. Crohn, the discoverer of Crohn's Disease (and my great grandfather on my mother's side) at left, with his sister Esther. They had ten other siblings. I'm working on a short-run book design of his memoirs.
When my father brought my mother to meet her future father-in-law, she exclaimed: "You have my grandfather's book!" My father's father looked uncomfortable; he'd bought a copy of "Understand Your Ulcer" not to read, but for his silly titles collection. Next to it on the shelf was "By Sledge and Horseback to Visit Outcast Siberian Lepers."
