Ulrike Meinhof, of the 1970s German terrorist Red Army Faction and Baader-Meinhof Gang? That's what the Wikipedia article on Faithfull says, here. (The Wikipedia entry on Broken English simply says "inspired by.") It is a great album, even so. I happen to prefer the later album, Strange Weather, but there's no getting around the edgy power of Broken English. I've also listened to Faithfull's interpretations of Brecht and Weill, and she is really quite outstanding - a real understanding of the material.
