Does this foundation accept applications?

Yes -- on its own tax return. Form 990-PF asks every private foundation whether it makes grants only to organizations it selects itself. Of the 91,758 foundations in our data that made a grant and answered, 78% said yes -- and applying to those is wasted effort. The Mary Duke Biddle Foundation did not check that box on its most recent filing, which puts it in the minority that is at least open to being approached.

This is the foundation's own statement to the IRS, not our judgement, and it says nothing about whether they have a form, a deadline, or an appetite for new grantees. Treat it as the reason this foundation is worth your research time, not as an invitation. Many small foundations of this kind have no website and no application process -- a letter of inquiry is the normal first step.

How big are its grants?

The median grant is $10,000. Half of everything it gave fell between $5,000 and $15,000; the smallest was $1,000 and the largest $565,000. If you are asking for materially more than the top of that range, you are asking the wrong foundation.

This is the complete list from its filings, largest first. Years funded is the number of separate tax years in which the organization received money -- more than one means a real relationship rather than a one-off.

75 of 151 (50%) received money in more than one year over the 4 years we hold.

Measured the way we measure every foundation -- what share of one year's grantees are funded again the next -- this one retains 44%, across 3 year-to-year transitions. The median foundation retains about 67%, so this one is less consistent than most. A high number means its list is close to settled and a newcomer has to displace someone; a low one means it is still moving money around, which is where an opening is.

What the money was for

Taken verbatim from the purpose field of its filings. This is the closest thing to a statement of what this foundation cares about, in its own words.

Tax years, not calendar years, and the most recent year is usually incomplete -- filings arrive about a year late, so a low final year means late paperwork rather than a foundation winding down.

Already committed for future years

Form 990-PF has a separate schedule for grants approved but not yet paid. The Mary Duke Biddle Foundation has 54 of them, worth $1,651,240. This is the one part of the filing that looks forward rather than back -- and it also tells you how much of the next year's budget is already spoken for.

Funders that support the same organizations

These funders gave to organizations this one also funded -- some private foundations, some community foundations and other grantmaking charities. Shared grantees are the strongest available signal that two funders have overlapping priorities, and a funder already backing your peers is a far warmer prospect than one that merely lists your cause.

How to approach this foundation

  1. Check you are its size. The median grant is $10,000. Asking for ten times that is the most common way small organizations waste a submission.
  2. Check you are in its geography. Its giving is concentrated in North Carolina.
  3. Read the recipient list above for organizations like yours. If nothing on it resembles your work, that is a real answer, and a cheap one to get.
  4. Look up the current filing before writing. The 990-PF names the foundation's officers and, where one exists, its application procedure. We link it below.

Where these numbers come from

Everything above is taken from The Mary Duke Biddle Foundation's own Form 990-PF filings, which the IRS publishes in bulk. We used 4 returns (tax years 2021-2024). Nothing here is scraped, inferred, or estimated.

Address of record on the latest return: 318 Blackwell Street, Durham, NC, 27701. This is the address the foundation gave the IRS; many small foundations file through an accountant or a bank trust department, so it may not be where post to a programme officer should go.

EIN 13-6068883 · See the original filings on ProPublica · How we build this

This is history, not an open call. Foundation returns are published about a year after the tax year ends. Nothing on this page is a deadline. It is a record of who this foundation has actually funded, which is the best available predictor of who it will fund next -- and a much better basis for deciding whether to write to them than a mission statement.
