A woman with strong family business links has topped the list of the most generous American donors in 2011, despite dying in 2006.
Margaret Cargill, an heiress of agribusiness Cargill, donated about $6 billion (€4.56 billion) last year, according to figures from the Chronicle of Philanthropy.
This figure far exceeded the amount given by the second person on the list – the late William Dietrich, who gave $500 million.
