For 10 points, name this hunchback whose voice can break windows, an inhabitant of WWII-era Danzig who beats a tin drum, created by Gunter Grass.
This character ends the novel in which he appears by singing about The Black Witch.  Earlier, he is caught by Father Weinhke when climbs onto a statue of the Virgin and Child in an attempt to induce a miracle, and also describes how his presumptive father is caught and beaten by the Home Guard during a game of skat; the latter is the son of a woman whose four wide skirts hide her husband, Joseph Koljaiczek, from the police upon their first meeting. As recorded on the five hundred paper sheets provided by his (*) keeper Bruno Munsterberg, this man eventually takes Alfred's surname, though he believes wife Maria to be the mother of his own son Kurt, before he joins Bebra and Roswitha's troupe of performing dwarfs and then gets sent to a sanatorium.
