An interesting thing about famous investors is that they're not all investors by trade. Thanks to his Gates Foundation, a charitable organization, Gates is, in fact, a famous investor. Further down the list is Kraft Heinz (KHC -1.54%), arguably one of the foundation's more intriguing holdings. With a yield of 6.2%, Kraft Heinz checks the dividend box, but it slashed the payout to conserve cash and reduce debt. The Gates Foundation got involved several years later, potentially sensing a turnaround opportunity.
