Notice that Hawking did not discover the so-called "Hawking Radiation," and initially Hawking did not think that Black Holes could emit radiation, but later affirmed that they could, based on Bekenstein's Black Hole Thermodynamic and Entropy theories.

From WIKI:

"In 1972, Bekenstein was the first to suggest that black holes should have a well-defined entropy. He wrote that a black hole's entropy was proportional to the area of its (the black hole's) event horizon. Bekenstein also formulated the generalized second law of thermodynamics, black hole thermodynamics, for systems including black holes. Both contributions were affirmed when Stephen Hawking (and, independently, Zeldovich and others) proposed the existence of Hawking radiation two years later. Hawking had initially opposed Bekenstein's idea on the grounds that a black hole could not radiate energy and therefore could not have entropy.[12][13] However, in 1974, Hawking performed a lengthy calculation that convinced him that particles can indeed be emitted from black holes. Today this is known as Hawking radiation. Bekenstein's doctoral adviser, John Archibald Wheeler, also worked with him to develop the no-hair theorem, a reference to Wheeler's saying that "black holes have no hair," in the early 1970s.[14] Bekenstein's suggestion was proven unstable, but it was influential in the development of the field.[15][16]

Based on his black-hole thermodynamics work, Bekenstein also demonstrated the Bekenstein bound: there is a maximum to the amount of information that can potentially be stored in a given finite region of space which has a finite amount of energy (which is similar to the holographic principle).[17]

In 1982, Bekenstein developed a rigorous framework to generalize the laws of electromagnetism to handle inconstant physical constants. His framework replaces the fine-structure constant by a scalar field. In 2004, Bekenstein boosted Mordehai Milgrom's theory of Modified Newtonian Dynamics (MOND) by developing a relativistic version. It is known as TeVeS for Tensor/Vector/Scalar and it introduces three different fields in space time to replace the one gravitational field.[19]..."

It’s important to understand that this discovery was mathematical in nature. Theoretical physicists working on math problems found a result that no one expected. Actual observations of black holes are difficult, and in fact, their very existence was debated for a long time after the math suggested that they do exist.
 
Exactly! I've tried to convince my wife that if she saves every last scrap of paper, the mass of everything collected together prevents anything that's actually important from being ever found again. She doesn't get it.
My daughter does it and I would throw away the oldest thing she stuff in her "closets" after she sleep. She never could give up her stuff including scratch paper, so in the end she lose them all.
 
Hawking never got the Nobel prize unlike his lesser known colleague Roger Penrose, who was awarded the Nobel Prize in Physics last year. Penrose who most people never heard of, is head and shoulders above Hawking as far as contributions to physic. Hawking wrote some best selling books for the layman.

I thought you were going to tie that into black holes somehow. Like if you had enough paper collected, it would collapse into a black hole. Maybe have a Dyson sphere around a star that's about 3 solar masses and then you have a bureaucracy that stacks enough paper to cause a stellar collapse into a black hole. Then you can talk about the black hole information paradox, but then you might end up talking about wormholes.
