The black hole was first conceived in 1784 by an English geologist named John Michell. Gravitation was well known by this time, and he simply devised the geometry of an object so massive that its escape velocity would exceed that of light. That it occurred to him to calculate the requirements for such a thing should perhaps be attributed to simple inspiration.

DavidK93 has it right, and the wikipedia entry is quite good. I'll just add a few points from personal experience.
The solution found by Karl Schwarzshild, just before he died in WW I, was unexpected. Einstein did not expect that there would be any exact, analytic solutions to the field equations of General Relativity.
It took about 50 years of work by a number of people before Schwarzshild's solution was understood as being a "black hole" in the modern sense. In the 1930s the "frozen star" idea was a misinterpretation that prevented progress in understanding Black Holes. It wasn't until solutions were found in coordinate systems co-moving with falling observers that more modern interpretations emerged in the 1970s.

I think someone like einstein theoraticaly calculated it. There is a lot of theory. Astronomers have observed such occurences.
But how is a theoy conceived? I have no idea, a lot of maths mabe.

black hole is just gravity go mad! you can't see them because they take in light photons!
