What actor's breakout role was the suspenders-loving nerd Steve Urkel on 'Family Matters'?

The story goes that nerdy neighbor Steve Urkel was only supposed to be a one-time guest shot, but the 'Family Matters' audience loved him so much that, for good or for bad, the character became a regular on the show that ran for nine years. With guest spots on 'House', 'Psych', and 'Bones', White has spent much of his subsequent career trying to convince people that, while he did "do that," he's capable of doing much more.
