Jürgen Acker was a Mesan citizen and slaver.
In 1922 PD, he served as communications officer of the slaving vessel Luigi Pirandello. His ship was on its way out of the Balcescu System when it was intercepted by a Royal Torch Navy vessel and subsequently destroyed by a Mesan Alignment to protect the secret of its passengers (two high-ranking scientists secretly smuggled out of Mesa). Acker himself was killed when the Torches opened fire on the slaver crew's shuttles after a group of their Marines died in the destruction of the Luigi Pirandello. (CS3)
