In a press conference this morning, the Danforth Foundation announced that it is closing after 84 years of operation at the end of this fiscal year, May 31, 2011.

The foundation's last act will be a $70 million donation to the Donald Danforth Plant Science Center.

The last donation is the largest in foundation's history, which has contributed $226 million to the Plant Science Center over the years.
