[2][3] During the Nazi era Eisenblätter got involved in the anti-Nazi communist resistance group associated with Robert Uhrig, Beppo Römer and John Sieg.

By the summer of 1941, Eisenblätter was in contact with the KPD foreign representative Charlotte Bischoff who passed her illegal and secret documentation that she used to produce the leaflets.

During questioning Eisenblätter took full responsibility for the leaflets and is credited with saving the life of Martha Butte in doing so.

Before her death Eisenblätter wrote a moving letter asking people not to mourn but recognise that she was reconciled to die for the ideals she held.

Eisenblätter was remembered by a postage stamp issued by the German Democratic Republic on 3 September 1959.
