Charles "Chuck" Feeney

Net worth: unknown

Donations: $8 billion

Giving focus: youth policy, science, human rights

The list of the biggest givers would be incomplete without a truly remarkable man - Charles Feeney. Once he decided to step on a philanthropic path by giving away all his money. Importantly, he has reached his lifetime goal. In 1960, he established the retail chain, DutyFreeShoppers, which brought huge yield. Thus, he was able to donate large sums anonymously thanks to that company. Being quite an old person, he announced that he would give away his entire multi-billion-dollar fortune to set an example. Few people appreciated his doing while the majority considered him crazy. Almost half of Feeney's donations were spent on education. Last year, his Atlantic Philanthropies foundation ceased to exist after giving away everything it had accumulated.
