In 1933, the Nazi Party rose to power. Moholy dated a Communist Member of Parliament, who was arrested in her apartment one day while she was out. She abruptly left Berlin, leaving all of her belongings including the bulky glass negatives of her Bauhaus photographs, which ended up in the hands of Walter Gropius. After having lived in Germany for two decades, she was forced to flee to Prague where she stayed with her family. She then went to Switzerland, Austria, Paris, before settling in London.
