Ulrike Marie Meinhof was a German left-wing militant, journalist and founding member of the Red Army Faction in West Germany, commonly referred to in the press as the "Baader-Meinhof gang". She is the reputed author of The Urban Guerilla Concept. The manifesto acknowledges the RAF's "roots in the history of the student movement"; condemns "reformism" as "a brake on the anti-capitalist struggle"; and invokes Mao Zedong to define "armed struggle" as "the highest form of Marxism-Leninism".
Meinhof, who took part in the RAF's "May Offensive" in 1972, was arrested that June and spent the rest of her life in custody, largely isolated from outside contact. In November 1974, she was sentenced to 8 years in prison for complicity in a near-fatal shooting in what had been her first RAF operation, the successful jailbreak of Andreas Baader in 1970.
From 1975, with Baader and two other RAF leaders, Gudrun Ensslin and Jan-Carl Raspe, she stood trial on further charges of murder and attempted murder. Before the end of the trial, she was found hanged in her cell in the Stammheim Prison.
