**Laplace** (1795) noted that
a consequence of Newtonian gravity and Newton's corpuscular theory of light was
that light could not escape from an
object of sufficiently large mass and small radius.

**Schwarzschild** (1916)
derived a general relativistic solution for the gravitational field
surrounding a spherical mass: *Schwarzschild black holes*.

**Wheeler** (1968)
studies the problem of gravitational collapse - coins the term
**black hole**.
