John Michell was about to answer that question but unfortunately he
did not know special relativity:

Clifford Will: "The first glimmerings of the black hole idea date to
the 18th century, in the writings of a British amateur astronomer, the
Reverend John Michell. Reasoning on the basis of the corpuscular
theory that light would be attracted by gravity, he noted that the
speed of light emitted from the surface of a massive body would be
reduced by the time the light was very far from the source. (Michell
of course did not know special relativity.)"
