Can the owner of a corporation be effected by what the corporation does?

I read that a corporations are considered a separate legal entity, much like a person. They can be charged with crimes, such as manslaughter and fraud, be sued and sue, and buy stock. I was just wondering if any problems with the corporation can effect the owner (founder, president, what?) of the corp. For instance, if the corporation is convicted of serious fraud, would the legal troubles be passed on the the owner of it? Or is he inapplicable to the crime? Also, if the owner of the corp was sued, or convicted of robbery or other money stealing crimes, and the money they stole or were being sued for was in a corporation, would the money be taken out of it? Or is it safe because it is separate from the person responsible?
