Why Is the Academy of Natural Sciences Closing? The Money, Building Sale and Condo Claim Explained

Philadelphia’s Academy of Natural Sciences museum is closing on September 30, 2026, but several claims spreading alongside the news go considerably further than the evidence.

The short version is this:

The financial problem is real. The Academy reported more than $110 million in assets in its latest audited financial statements, but only about $1.46 million was classified as available for current general use. Most of its financial wealth is invested, restricted by donors, tied up in trusts, or represented by property and other assets that cannot simply be spent on museum operations. Drexel University was already providing more than $8 million a year in operating support.

There is also a real property story. Reporting indicates that relocating the Academy’s collections and eventually selling its valuable Benjamin Franklin Parkway building has been contemplated. The building is not protected by Philadelphia historic designation, and its zoning allows some residential development.

What has not been established is the most dramatic version circulating online: that a condo developer is waiting to demolish the museum, or that the museum is being closed specifically to make way for condominiums.

No buyer, executed sale, condominium proposal, demolition permit or approved redevelopment plan establishing that scenario has been publicly identified.

And the approximately 19 million scientific specimens are not scheduled to be discarded when the museum closes.

Those distinctions matter because the underlying story is complicated enough without turning legitimate unanswered questions into facts that have not been proved.

What exactly is closing on September 30?

The Academy of Natural Sciences and its museum are related, but they are not the same thing.

The public museum is closing.

The Academy’s scientific research institution, collections, Library and Archives are supposed to continue operating.

Drexel and Academy leadership announced on September 1 that the museum would cease operations September 30. Its final Sunday of regular public visitation is September 27.

The Academy says its collections contain more than 19 million biological specimens, fossils and other scientific resources, including more than 73,000 type specimens. A type specimen is particularly important because it serves as the physical reference used to define a species.

The collection therefore functions less like a warehouse of old objects and more like scientific infrastructure used by researchers around the world.

So a claim that "the Academy is closing" needs qualification.

The museum is closing. The scientific Academy is not.

That still represents the loss of an institution that has exhibited natural history to the public since 1828, but it is very different from 19 million specimens suddenly being abandoned on September 30.

Why does Drexel say the museum has to close?

The official explanation centers on a combination of declining attendance and rising costs.

In its closure announcement, Drexel and the Academy said they tried after the COVID-19 pandemic to rebuild attendance through new exhibitions, galleries and programming, but that visitor behavior had changed while operating costs continued to increase.

Leadership said continuing to operate the museum in its current form and building would increasingly consume resources needed for scientific research and preservation of the collections.

There were warning signs before the September announcement.

The museum reduced its normal operating schedule in October 2025, citing financial pressure, including reduced attendance and concerns over research funding. By 2026, Drexel and Academy officials were publicly negotiating the future of their 2011 affiliation while Philadelphia Mayor Cherelle Parker’s administration and Pennsylvania Gov. Josh Shapiro’s office were involved in discussions.

But the official explanation creates an obvious question.

How can an organization with more than $110 million in assets be in enough financial trouble to close its museum?

The audited financial statements provide much of the answer.

The Academy has $110 million in assets. That does not mean it has $110 million to spend.

The Academy’s fiscal year 2025 audited financial statements reported $110.2 million in total assets.

That number sounds enormous compared with an institution reporting annual operating expenses of about $23 million.

But total assets and money available to pay current expenses are very different things.

According to the Academy’s 2025 audited financial statements:

The most revealing figure is not $110 million.

It is $1.46 million.

That is what the Academy’s auditors calculated was available at June 30, 2025, within one year to meet general cash expenditures, before counting future operating revenue such as admissions, memberships, grants and Drexel support.

Why can’t the Academy just spend its investments?

Because most of them are not ordinary savings.

The financial statements say the Academy’s investment portfolio consists primarily of donor-restricted and board-designated endowment funds. Donor-restricted money must generally be used for the purposes specified by the people or organizations that gave it.

A donation endowed to support a scientific research chair, for example, is not automatically available to pay gallery security guards, electricity bills or general museum payroll.

The Academy reported approximately $96.3 million in net assets with donor restrictions at the end of fiscal 2025.

Its accounting records break that restricted amount into roughly:

• $76.6 million for endowments
• $11.7 million in beneficial interests in trusts
• $7.9 million for programs and capital expenditures
• smaller amounts in other restricted categories

That explains why looking only at total assets gives a misleading picture of operating flexibility.

The Academy was already spending millions from its endowment

The endowment was not simply sitting untouched.

The Academy distributed approximately $4.22 million from its endowment for operations in fiscal 2025, up from about $4.08 million the previous year.

Its board had adopted a spending rule based on 7% of the average fair value of pooled endowment assets over the prior seven years, except where individual donors required a different rate, commonly 5%.

That 7% figure is notable.

Pennsylvania law permits nonprofits using the relevant total-return election to select an annual spending percentage generally between 2% and 7%. In other words, the Academy’s stated 7% policy sits at the top of that standard statutory range.

That does not prove no additional endowment money could ever be accessed. Restricted funds can sometimes be modified through donors, courts or other legal mechanisms under particular circumstances.

But it does undermine the simple argument that management could solve the problem merely by deciding to "use the endowment."

The Academy was already drawing millions from it.

Another number buried in the audit shows the longer-term problem

The Academy reported $9.8 million in total net assets without donor restrictions.

At first glance, that also sounds like available money.

But the notes divide those unrestricted net assets into three components:

• Operating: negative $19.144 million
• Physical plant: positive $27.291 million
• Board-designated quasi-endowment: positive $1.679 million

Those components net to the positive $9.826 million headline figure.

The negative operating balance does not mean the Academy literally owed someone $19.1 million. It is an accounting measure, not a checking-account balance.

But it does show why "the Academy has millions in unrestricted assets" does not fully describe its operating position. Much of the positive value was tied to its physical plant rather than accumulated operating resources.

Drexel was already providing more than $8 million a year

The Academy’s financial problem also cannot be understood without Drexel.

In fiscal 2025, Drexel provided $8.288 million for Academy operations.

The previous year, it provided $8.914 million.

Compare that with fiscal 2019, when Drexel provided approximately $4.152 million.

Drexel’s annual support had therefore nearly doubled since 2019.

That changes the interpretation of the closure.

This was not a museum comfortably supporting itself until Drexel abruptly removed all assistance. Drexel had become an increasingly important source of operating revenue.

The problem is that Drexel developed major financial pressures of its own.

Drexel has been cutting costs across the university

Drexel reported a $63.4 million decrease in net assets from operating activities in fiscal 2024, according to its audited financial statements. The university subsequently launched a multiyear financial-resiliency effort targeting $150 million in expense reductions, cost avoidance and additional revenue.

By May 2026, Drexel said it had implemented approximately $93 million in permanent financial strategies, with additional reductions and revenue measures underway.

Drexel president Antonio Merlo said in April that the university was projecting a roughly $20 million deficit for the year, improved from the much larger 2024 shortfall but not yet eliminated. First-year enrollment had also declined sharply.

Against that background, an annual Academy subsidy above $8 million becomes considerably more consequential.

None of this proves that closing the museum was the only possible solution.

It does establish that the stated financial problem is not fictitious.

What happened to the $70 million raised for the Academy?

This is one of the strongest questions raised by people reacting to the closure.

And the $70 million number is real.

Drexel’s final accounting of its major Campaign for Drexel fundraising drive says $70 million was raised for the Academy of Natural Sciences of Drexel University. The overall university campaign closed June 30, 2022, after raising more than $800 million.

But "$70 million was raised for the Academy" does not mean the Academy received $70 million in unrestricted cash that should still be available to operate the museum in 2026.

Drexel’s own campaign history identifies substantial Academy gifts whose purposes were restricted or endowed.

Examples include:

Drexel also announced a $3 million Dolan family commitment for water research, including plans for a $2.5 million endowment.

Those are real Academy resources. But they are not interchangeable with unrestricted operating cash for a public museum.

Can we account for all $70 million?

Not from the public campaign summaries we found.

That is an important distinction.

The available Drexel materials demonstrate that the $70 million figure is genuine and that millions of dollars went toward endowed positions, research, strategic programs and collection care.

They do not provide an easily accessible donor-by-donor, dollar-by-dollar public ledger explaining the entire $70 million.

So two competing statements can both be misleading:

"Drexel raised $70 million, therefore the museum cannot really have a financial problem."

and

"There is nothing to explain about the $70 million."

There is something worth explaining.

A complete public accounting of how that $70 million was structured, restricted, spent or added to endowments would help resolve one of the biggest sources of confusion surrounding the closure.

Is the Academy’s building actually going to be sold?

A sale is a serious possibility, but no completed sale has been announced.

The Philadelphia Inquirer reported, citing a source close to negotiations, that the longer-term aim was to relocate the collections and sell the Academy-owned building. Drexel publicly responded that the building would continue housing the collections and laboratories while possible paths forward were evaluated.

More recent reporting has continued to describe an eventual collection relocation and building sale as the anticipated direction.

That makes concern over the building reasonable.

It does not establish what a future buyer would do with it.

Is the museum really being demolished for condos?

There is currently no public evidence establishing that claim.

There are, however, several facts that help explain why the idea spread.

The Academy’s building at 1900 Benjamin Franklin Parkway:

• occupies valuable Center City property;
• is owned by the Academy;
• is not currently listed on the Philadelphia Register of Historic Places;
• has an assessed property value of more than $28.7 million, according to city records cited by The Inquirer;
• and sits in an RM-4 zoning district within the Center City/Parkway overlay.

The Inquirer reports that the zoning permits low-rise residential development, including townhouses or smaller apartment buildings.

Philadelphia City Councilmember Jeffery Young Jr. has said his office is examining zoning options to protect the Parkway district, while the Preservation Alliance for Greater Philadelphia is investigating a potential historic nomination for the Academy building.

So residential redevelopment is not an absurd hypothetical.

It is simply not the same thing as an actual condo project.

As of September 21, we found no publicly identified:

That is where the evidence presently stops.

If a sale agreement, development application or demolition permit appears later, the assessment should change with the evidence.

The building is old, but "not in a historic zone" is not quite right

Another claim circulating online is that the building can be demolished because it is "not in a historic zone."

The important underlying point is true, but the terminology is imprecise.

The Academy property is within Philadelphia’s Center City/Parkway zoning overlay.

What it lacks is individual designation on the Philadelphia Register of Historic Places, which can provide legal protection against demolition and major alterations.

The Academy moved into its current building in 1876. Despite its age and prominent location, no one ultimately completed a successful local historic nomination.

The Preservation Alliance says it believes the property qualifies and is now examining the process.

That means the museum’s closure has exposed a preservation vulnerability that apparently attracted little attention while the institution seemed secure.

Who actually owns the Academy and the building?

The governance structure is another source of confusion.

The Academy of Natural Sciences is a separate 501(c)(3) nonprofit organization affiliated with Drexel University. Its operations are overseen by its own Board of Trustees, and its endowment remains dedicated to the Academy.

The Academy’s audited financial statements describe it as a nonprofit subsidiary of Drexel under the 2011 affiliation agreement.

In other words, "Drexel owns the museum" is an oversimplification.

But it would also be misleading to imply that Drexel has no control over major decisions.

The Academy’s 2021 bylaws give Drexel substantial approval rights.

Among them:

• the Drexel Board must approve decisions materially affecting the ownership, preservation or maintenance of the Academy’s scientific resources;
• the Drexel Board approves the Academy’s annual operating and capital budgets;
• and the Drexel president must approve an unbudgeted sale, lease or other conveyance of Academy real property.

So the Academy owns assets and maintains its own nonprofit identity, but Drexel has meaningful governance authority over major financial and institutional decisions.

Did the Academy really never ask Philadelphia for help?

This claim requires another distinction.

Several Philadelphia City Council members say the Academy did not approach City Council for help before announcing the museum closure.

Councilmember Anthony Phillips said leadership had not come to Council even once to say the institution was in dire need of assistance. Councilmembers Nina Ahmad and Jeffery Young Jr. likewise said they were surprised by the announcement.

Council has since moved toward hearings examining how the decision was reached and whether alternatives exist. Ahmad said the proposed hearings would include subpoena authority.

But saying the Academy "never went to City Hall" is broader than the evidence supports.

Months before the closure announcement, Drexel and Academy officials were already discussing the institution’s future with the offices of Mayor Cherelle Parker and Gov. Josh Shapiro. Shapiro asked former U.S. ambassador and Comcast executive David L. Cohen to help facilitate negotiations.

The day after the closure announcement, the City of Philadelphia agreed to loan Deputy Mayor Patricia "Trish" Wellenbach to the Academy as a senior adviser during the transition. She remains a city employee.

The accurate version is therefore:

City Council members say they were not approached for financial help before the closure decision. Other parts of Philadelphia and Pennsylvania government were already involved in discussions about the Academy’s future.

What happens to the 19 million specimens?

This is arguably more important scientifically than what happens to the galleries.

There is currently no announced plan to discard the collection.

Drexel and Academy leadership say preservation of the collections is the priority behind restructuring the institution.

For now, the Parkway building is expected to continue housing collections, laboratories, the Library and Archives and scientific research.

A later relocation remains possible, particularly if the building is ultimately sold.

That would be a major undertaking.

The collection includes biological specimens, fossils and other materials assembled over more than two centuries. The Academy says researchers lend, digitize and study specimens from the collections worldwide, with tens of thousands serving as type specimens central to taxonomy and biodiversity science.

Moving such a collection is therefore not equivalent to moving office furniture.

Any future relocation would raise questions about climate control, fire protection, pest management, fluid-preserved specimens, chain of custody, cataloging, accessibility to scientists and the physical safety of irreplaceable objects.

Those details have not yet been publicly resolved because a relocation plan has not been announced.

Did Brown University really throw away a natural-history collection?

Surprisingly, this part of the viral warning is based on a real historical event.

Brown University’s former Jenks Museum of Natural History and Anthropology declined after the death of its founder and eventually closed. Its collections were placed into storage.

In 1945, Brown records say 92 truckloads of specimens and artifacts were taken to a university dump along the Seekonk River. Only a small portion of the original collection survived.

That history is legitimately disturbing.

It demonstrates that institutions once assumed to preserve scientific and cultural collections indefinitely can fail to do so.

But historical precedent is not evidence that the Academy of Natural Sciences intends to repeat it.

Brown’s Jenks Museum is useful here as a warning about why collection stewardship matters, not as proof of a secret disposal plan in Philadelphia.

Could the museum still remain open?

There is active political and community pressure to reconsider the decision, but whether that can produce a financially workable alternative remains unknown.

Philadelphia City Council members have called for public hearings into the closure and possible solutions.

Councilmember Nina Ahmad has publicly discussed ideas including state assistance, bonds, historic designation and potentially exploring whether restrictions on some institutional assets could legally be modified.

Those are proposals to investigate, not money already secured for the museum.

Drexel and Academy leadership maintain that they examined alternatives before determining that the existing museum model was unsustainable.

Council members want more information about what those alternatives were and how management reached its decision.

That hearing process could become important because the public financial statements answer the broad question of whether financial strain exists.

They do not answer every question about whether closure was the only viable response.

A timeline of how the Academy reached this point

2011: The Academy and Drexel formally affiliate. The Academy remains a separate nonprofit organization while becoming a Drexel subsidiary.

2019: Drexel provides approximately $4.15 million in annual Academy operating support.

2020: COVID-19 disrupts museum attendance and operations.

June 2022: Drexel’s major fundraising campaign concludes. Final campaign materials credit $70 million to the Academy.

FY2024: Drexel provides approximately $8.91 million in Academy operating support while Drexel itself reports a $63.4 million operating decrease in net assets.

FY2025: Academy financial statements show $110.2 million in assets, but only $1.46 million available at year-end for current general use. Drexel provides $8.29 million in operating support.

October 2025: The museum reduces its regular operating days amid financial pressure.

April 2026: Negotiations over the Drexel-Academy affiliation become public. The governor and mayor’s administration are already involved.

September 1, 2026: Drexel and Academy leadership announce that the public museum will close September 30.

September 2: Philadelphia loans Deputy Mayor Trish Wellenbach to the Academy as a senior adviser.

September 17: Philadelphia councilmembers announce efforts to hold hearings into the closure and possible alternatives.

September 27: Scheduled final day of regular public museum hours.

September 30: The museum is scheduled to cease operations.

What is verified, what is plausible and what remains unproven

The evidence does not support either of the simplest versions of this story.

It is misleading to say:

The Academy has $110 million, so the financial crisis must be fake.

Its audited statements show a genuine distinction between institutional wealth and spendable operating resources, substantial donor restrictions, millions in annual endowment withdrawals, negative operating net assets and reliance on Drexel support.

But it is also premature to say:

Drexel is closing the museum because it already has a deal to demolish it and build condos.

A building sale and collection relocation are credible possibilities. The property’s lack of historic designation and residential zoning make redevelopment a legitimate issue to investigate.

An actual condo project has not been established.

The most defensible conclusion today is more complicated:

The Academy entered 2026 with a genuine operating and liquidity problem while relying heavily on a university facing financial pressures of its own. Closing the museum reduces one expensive part of the institution while protecting research and collections, according to Drexel and Academy leadership. At the same time, the closure creates the possibility that a valuable, unprotected property could eventually be sold and redeveloped. Whether that real-estate outcome influenced the closure decision beyond the stated financial considerations remains unproven.

That is precisely why the next round of records matters.

What we still do not know

Several important questions remain unanswered.

What is the complete accounting of the $70 million credited to the Academy during the Campaign for Drexel?

Public materials explain some major gifts but do not provide a complete allocation of the entire amount.

Exactly what alternatives were modeled before leadership decided to close the museum?

Drexel says alternatives were considered. City Council wants greater visibility into that process.

How much money would actually be required to keep the existing public museum operating?

The institution has disclosed its overall finances, but no detailed public "keep the museum open" budget has been released showing the exact annual subsidy and capital improvements required.

Will the Benjamin Franklin Parkway building actually be sold?

That possibility has been credibly reported, but no sale has been publicly announced.

If it is sold, who will buy it and what will replace it?

There is currently no documented condominium project or identified developer.

Where would the scientific collections go if they eventually leave the building?

No final relocation site or detailed moving plan has been announced.

Those are the questions that should determine how this story evolves.

Not rumors, and not institutional assurances by themselves.

The underlying documents should.
