Herbert Grasse

[3] In June 1941, he founded and became a publisher and editor of the Die Innere Front along with John Sieg and Otto Grabowski.

[3] In 1933, Grasse along with the KPD functionary Alfred Schaefer, who worked in Agitprop, became involved in the production of the communist Neuköllner Sturmfahne.

[6] The paper had been published sporadically since 1932 by KPD functionaries Reinhold Sasse, Fritz Plumboom and Walter Klauss as well as Fritz Grünberg, who was followed by Otto Grabowski but successive arrests by the Gestapo had led to the publishing team in the Neukölln area rapidly changing.

He was introduced to the resistance group around Wilhelm Schürmann-Horster where he would eventually meet Hans Coppi and John Sieg.

[5] In December 1941 it was decided by John Sieg, Grasse and Otto Grabowski (1892–1961) that Guddorf's report should be publicised and this initiated the production of the Die Innere Front.
