It wasn't Einstein who first conceived the idea of a black hole, one of the earliest records of someone speculating what would happen if a star got so massive that it's gravity would pull back light was John Michell, who termed them 'dark stars'. If that name doesn't ring a bell, think of the Cavendish experiment to weigh the Earth. That apparatus was conceived by the same man.
