“Typhoid” Mary Mallon

This week, we’re covering the strange, sad case of Mary Mallon, one of America’s most notorious killers—who never technically committed a crime. When is it illegal to spread a disease? Why did the Health Department have the power to detain people indefinitely? Does Mary deserve her infamy, or was she a victim of a system that was stacked against her from the start?

Content notes: This is mostly about an epidemic of typhoid fever, but it will also touch on other disease outbreaks and US laws around quarantining people and charging people for spreading diseases. We’ll be discussing the COVID-19 pandemic at the end of this episode. The death of a child is mentioned.

About Mary Mallon and the other people in this story

(Note: Quite a few sources refer to George Soper as “George Sober.” I don’t know if he went by both names or if some early misprint got reproduced, but I went with Soper since that seems to be the name he used for his later work.)
