The Jack the Ripper killings coincided with the conception of Adolf Hitler. Coincidence? Chapter Five of Alan Moore and Eddie Campbell's From Hell, focused on the Ripper killings, shows that conception. Adolf's mother Klara has a vision of blood and war (shown above), even as the Ripper says "It is beginning, Netley. Only just beginning. For better or worse, the twentieth century. I have delivered it."
