It’s unfortunate how the passing of Steve Jobs is bigger news than the recent passing of Dennis Ritchie. The world owes a debt of gratitude to Dennis, and most people don’t even know it. You’ll be hard pressed to find a household that doesn’t include technology that shows his influence.
Even without UNIX, there’s the C programming language influence. Heck, UNIX had a clear influence on DOS which funded MS Windows, so I’m not sure you could find a computer anywhere that Dennis hasn’t influenced.
