Few of America’s richest families are among the country’s biggest donors, The Seattle Times reports, citing The Chronicle of Philanthropy’s annual list of top givers.

Of the 400 wealthiest Americans, as listed by Forbes, only 17 appear on the Chronicle’s latest Philanthropy 50, which ranks donors by the amount they gave in 2009.

The biggest donors last year were the hedge-fund billionaire Stanley Druckenmiller, who ranks at No. 56 on the Forbes roster, and his wife, Fiona, who together gave $705-million to their foundation.
