Dierk Hoff was not really a member of the Baader-Meinhof Gang per se, but he was instrumental in their bombing "success" in 1971 and 1972. Dierk was a Frankfurt metal sculptor who was recruited late in 1971 by Holger Meins to make props for a film about revolutionaries. By the time that he realized that his "props" were in fact real (hand grenades, etc.), Hoff was in too deep.

Hoff's most infamous invention was the so-called "baby bomb" which was attached to a woman's shoulders and carried on her belly under her blouse. It looked exactly like the distended belly of a pregnant woman. After the woman dropped the bomb in a discreet area of a public place, she would blow up a balloon and slip it underneath her dress, where the bomb was originally, and walk away. Fortunately the bomb was never used.

Hoff was arrested in 1975
