For around twelve years, from 1919 to 1931, it remained undiscovered that Joseph Einsmann, the hard-working laborer, caring family man, and singer in two church choirs, was in fact a woman named Maria. For twelve years, in order to find work at all, she had assumed the identity of her estranged husband. Only as Joseph Einsmann was she able to earn a living for herself, her partner Helene Müller, and their two daughters.

The story of her discovery and the 1932 trial against Maria Einsmann and Helene Müller made headlines far beyond Mainz. Even local newspapers in non-German-speaking countries published articles about the woman in men's clothing.

The Women's Office shows the media impact of the Maria Einsmann case in 1931 and 1932 with a brochure published especially for the naming of the square, the 61st anniversary of Maria Einsmann's death on March 4, and International Women's Day "The woman in men's clothing. The case of Maria Einsmann." The brochure offers an excerpt from the wealth of newspaper articles published at the time.
