Cohn's contribution allowed practical treatment of this previously incurable and fatal illness, for the next 20 years.

    “If the devil were to offer me a resurgence of what is commonly called virility, I’d decline. “Just keep my liver and lungs in good working order,” I’d reply, “so I can go on drinking and smoking!””
    —Luis Buñuel (1900–1983)

    “When you got to the table you couldn’t go right to eating, but you had to wait for the widow to tuck down her head and grumble a little over the victuals, though there warn’t really anything the matter with them. That is, nothing only everything was cooked by itself. In a barrel of odds and ends it is different; things get mixed up, and the juice kind of swaps around, and the things go better.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    “I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
    —Hippocrates (c. 460–c. 370 B.C.)

    “Masses are rude, lame, unmade, pernicious in their demands and influence, and need not to be flattered but to be schooled.”
    —Ralph Waldo Emerson (1803–1882)
