Apple CEO Tim Cook, 58, leads the first company in the world to become worth $1 trillion.

But he actually is a lot less wealthy than leaders of other, less revenue-generating corporations.

Cook, who is the son of a shipyard worker and a pharmacy employee, said he's not motivated by money, and that shows through in what we know about the private CEO's habits.

Cook's actual net worth is certainly even higher than that — but information on his property, investment portfolio, and cash on hand isn't publicly available.

Jeff Bezos, Bill Gates, Mark Zuckerberg, and Larry Page are all worth tens of billions.
