  • Science Division: Museum scientists contribute knowledge about the earth, its inhabitants, and beyond by conducting research across multiple scientific disciplines including anthropology, earth sciences, health sciences, space sciences, and zoology. Staff also manage, curate, and provide access to the Museum's collection of 4.3 million objects and specimens. In 2023, Science Division staff published 37 peer-reviewed journal articles, books, and book chapters, produced 21 popular books, book chapters, articles, and were cited 1,920 times. During this time, staff also hosted 196 researchers and fielded 253 research requests from the scientific community. The Science Division also engaged in abundant educational outreach by communicating science to almost 45,000 members of the public through courses, events, tours, lectures, and field trips. 6,557 of those guests attended collection open houses or behind-the-scenes tours of the Avenir Collections Center. Science staff supervised 35 interns, hosted 20 Teen Science Scholars, and mentored 15 undergraduate and graduate students. The division's volunteer program continued to rebound following the pandemic and in 2023, 900 volunteers contributed over 104,638 hours.

The first 25 listed. Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

The 10 largest by cash amount. The API serves every itemized grant.

Related organizations

From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
