It is, therefore, natural that I should desire after having made provision for the immediate members of my family and others whom I have seen fit to remember, that the remaining portion of my estate be utilized for charitable needs.At the time, du Pont's assets included seven Florida National Banks, significant landholdings in Northwest Florida, E. I du Pont de Nemours Company shares, and the Nemours and Epping Forest estates.

Thornton, former CEO of St. Joe Company and Florida East Coast Industries, succeeded Ball and was chairman of the trust for 23 years.

Hugh Durden, corporate trustee since 1997, now a retired executive from Wachovia Bank, was elected chairman on January 24, 2005.

The problem was that duPont's will stipulated an annual disbursement of the amount equal to 3 percent of the trust's value.

The new headquarters of the trust is a 40,000-square-foot (3,700 m2), five-floor building on the St. Johns riverfront in Jacksonville, Florida which was scheduled to open October 1, 2008.

Three 10,000-gallon underground cisterns capture rainfall, which is then used for landscape irrigation, so a large retention pond is not required.

The four-story atrium is capped by a pyramid-shaped skylight, flooding the interior of the building with sunshine and warmth during cool months.

Lastly, heating and cooling systems are high efficiency and limit power usage during peak demand periods.
