My barber has some Jack Davis' old west prints in his shop. When I identified them, he said that Jack pronounced his last name "Day-vees." I always thought it was "Day-vis." Also, I somehow thought Len Wein's last name was pronounced "Ween," but I thought, when I saw his passing, that it might be pronounced "wine."
Jack Davis pronounced his last name "Davis." I never met anyone named Davis who pronounced it "Day-vees." Len Wein's last name rhymes with "keen," "clean," "green," "serene," "machine," "bean," "teen" and even "Wolverine" — but never "mean."
