Katherine’s father, an enigmatic tannery owner. At first, Morten seems to be a harmless old trickster with a liking for chaos and social upset; while he doesn’t understand the concept of bacteria and so doesn’t take seriously Dr. Stockmann’s findings of water contamination in the baths, he thinks the report is a good prank and encourages his son-in-law to frighten those in power. But when Dr. Stockmann implicates his own tannery in the contamination Morten turns on him, using the money he planned to leave Katherine to buy shares in the baths and hoping that his son-in-law will retract his findings in order to make the shares valuable again. Through these actions, Morten demonstrates that he has no true sense of obligation to his family or society and no concerns except for his own social status. Morten is an amoral character, but his obsession with his reputation above all paradoxically contributes to Dr. Stockmann’s obsession with his individual rights. While the two men live according to different moral paradigms, their more destructive qualities are ironically similar.
