If Stephen Hawking is considered a High-Level character [21-30?], then he better be damn well able to break down that door. A crippled person doesn't get to Epic levels without learning how to move around environments. He could probably use telekinesis to bust open the door. Or maybe he summons a black hole for a micro-nanosecond to obliterate the door. . .

In your example, while Hawking's STR score would be small, his experience would allow him to distract, cheat or befuddle the opponent in some other way so that his low STR didn't matter as much.
As to his character stats -
Since Stephen Hawking would be an NPC (unless Stephen Hawking is playing D&D and wants to play himself

), and the 4E DMG says ". . . only give them the things you'll need to run them in an encounter or an adventure." and "Most don't have classes or even roles . . ." (pg. 187), then he wouldn't necessarily have, or even need, a level bonus.
Stephen Hawking would be an expert at certain things, for everything else he would be no different than any commoner NPC with no levels (except with decreased movement).
As a 4E* DM this is what I would use as his info:
*(or actually any edition DM since this concept can be used in any edition with no real shoehorning involved)
Real World:
Stephen Hawking
Master Theoretical Physicist and Mathematician (Fantasy setting: Sage/Seer)
Str: 1
Dex: 1
Con: 5
Int: 25
Wis: 25
Cha: 2/18*
(*situational - viewers usually have an extreme reaction when first meeting, whether good or bad, he's never viewed as "average". Usually though, after meeting him, most people see him as quite charismatic.)
Movement: 1
Skills:
Diplomacy: 16/20* (see Charisma)
Insight: 20
Knowledge,
General: 20
Knowledge*;
Mathematics, Cosmology, Physics, Theoretical Physics, Quantum Mechanics: 50
Knowledge, Teaching: 30
Perception: 20
(in a fantasy setting substitute in Knowledge;
Planes,
Religion,
Arcana,
Engineering,
Mathematics. Also add some appropriate Arcane Powers and Rituals, and add a couple of new magic items - a Telepathic speaking device and a Telepathically controlled conveyence - cart, wheeled chair, floating chair, etc.)
As to Stephen Hawking overcoming a door - it's obvious, he would either explain to a PC how to overcome the door using Intelligence and exploitation of scientific principles, or, he'd blast it open with a concentrated burst of
Hawking Radiation, a unique energy harnessed by him alone (not
Telikinesis or any other power or energy - come on,
everyone knows this).
