text:  Slayer guitarist Jeff Hanneman wrote " Angel of Death " after reading books about Nazi physician Josef Mengele while on tour with the band : " I remember stopping someplace where I bought two books on Mengele . I thought , ' This has gotta be some sick shit . ' So when it came time to do the record , that stuff was still in my head — that 's where the lyrics to ' Angel of Death ' came from . "
