Why was Marie curie mistaken for a spy?

Answer 1

Marie Curie was mistakenly suspected of being a spy due to her close ties with military officials and her involvement in developing mobile X-ray units during World War I. Her work, which involved handling radioactive materials and collaborating with various governments, raised suspicions during a time of heightened paranoia and espionage. Additionally, her foreign nationality and prominence in a male-dominated field contributed to misunderstandings about her intentions. Ultimately, these factors led to unfounded rumors about her being a spy.
