If it was Hitler, Himmler, or Goebbels, I'd agree with the comments. But Heidrich to me isn't as strongly referential as the others... I had to look it up before I knew who it was, and I do a fair amount of WW2 reading. To me at least, it just doesn't evoke anything in the way those other three names would, and it's still commonly used in today's world.
