As the stock market resurged last year, so did the charitable giving of the super wealthy. America’s top 50 donors gave a total of $10.4-billion in 2011, up from $3.3-billion the previous year, according to a Chronicle study. One big bequest boosted the total significantly; excluding that gift, the philanthropists on The Chronicle’s list of the most generous Americans contributed $4.4-billion.
