In Cape Town this week Feeny was awarded the 2014 Inyathelo "Lifetime Philanthropy Award for Giving While Living." His contribution to post-apartheid reconstruction has included around R3bn (€215m) donated through Atlantic Philanthropies.
Shelagh Gastrow, executive director of Inyathelo, described the fund as "a key partner for education, health and human rights in South Africa through the many organisations it supported over the years".
The Inyathelo Awards recognise "excellence and leadership in contributing to social development and change in South Africa".
After making a fortune in the duty free industry, Irish-American Chuck Feeney, who is now in his 80s, pioneered the concept of "giving while living."
