Today in Labor History February 18, 1943: The Nazis arrested the members of the White Rose movement. The activist group called for opposition to the Nazi regime through an anonymous leaflet and graffiti campaign. The Nazis put on a show trial in which none of the defendants were allowed to speak. They executed Hans and Sophie Schol, and Christoph Probst on February 22, 1943. White Rose leaflets openly denounced the persecution and mass murder of the Jews. They might have taken their name from the poem "Cultivo una rosa blanca," by Cuban revolutionary and poet, Jose Marti. Alternatively, they may have gotten it from the B. Traven novel, “Die Weiße Rose” (The White Rose).” Traven served on the Central Council of the short-lived Bavarian Soviet Republic. He escaped the terror that followed the crushing of the Republic and fled to Mexico, where he wrote numerous novels, including “Death Ship” and “The Treasure of the Sierra Madre.”
