What Eleutherian Mills-Hagley Foundation Inc does
Mission
Hagley Museum and Library seeks to inspire all people to be innovative in their own lives through investigation and exploration of our historical collections, the original DuPont powder yard, and online resources.
As stated on its FY2024 Form 990.
Programs
Hagley Museum is located on 235 acres along the banks of the Brandywine River in Wilmington, Delaware. Hagley is the site of the gunpowder works founded by E. I. du Pont de Nemours in 1802. This example of early American industry includes restored mills, a workers' community, and the ancestral home and gardens of the du Pont family. Hagley exhibits objects and artifacts that interpret the unfolding history of American business, technology, and innovation, and its impact on the world.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $219M to $182M (−17%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2019 1% · 2020 31% · 2022 14% · 2023 26% · 2024 6%. Grants only. Government contracts and fees sit inside program revenue.
29% of Eleutherian Mills-Hagley Foundation Inc’s revenue is contributions — more earned-revenue than three-quarters of its peers (58% for the typical peer).

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $654k arriving through sponsors registered in 9 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
