Rockefeller family
John D. Rockefeller gave away US$540 million over his lifetime (in dollar terms of that time), and became the greatest lay benefactor of medicine in history. His son, "Junior" also gave away over $537 million over his lifetime, bringing the total philanthropy of just two generations of the family to over $1 billion from 1860 to 1960. Added to this, the New York Times declared in a report in November, 2006 that David Rockefeller's total charitable benefactions amount to about $900 million over his lifetime.
