Katharina Jacob (née Emmermann, formerly Hochmuth; 6 March 1907 – 23 August 1989) was a teacher and member of the German Resistance movement against National Socialism.
She was married to Franz Jacob, a German Resistance fighter who was executed by the Nazis.
After the Nazis seized power in 1933, Walter Hochmuth appeared on a wanted poster and went underground.
Political friends took care of Ursel, as well as neighbors and her teacher at school, Gertrud Klempau.
She continued her Resistance activities, collecting food ration cards for forced laborers and listened to Radio Moscow.
[1] A wave of arrests in Hamburg in October 1942 prompted Franz Jacob to flee to Berlin.
Jacob took a road trip with her daughters, stopping secretly to see Franz in Berlin and staying just one night.
Prosecutors sought the death penalty for Groß, but she received a ten-year sentence at hard labor in a Zuchthaus instead.
Lack of evidence, prevented the court from passing sentence on Jacob, but nonetheless, she was not released.
[1] Fifty-five million people in Germany and Europe were wiped out; gassed, fallen on the front lines, died where they lived.
