English: Skeleton of Jacob Karrer, constructed by Vesalius in 1543, in the Basel Vesalianum (Anatomisches Museum Basel). On the 12th of May, 1543, Jakob Karrer von Getweiler was executed in Basel, Switzerland. Reports say he was beheaded, although hanging was a more usual mode of execution. Karrer was a bigamist who attacked his legal wife with a knife after she discovered his second wife. According to a contemporary account, Karrer was a habitual criminal, and he left his wife grievously injured. Although she did not die, he was sentenced to death. After his death, Vesalius dissected Karrer, in front of an audience, than constructed an articulated skeleton with his bones. More details here
