Mütter Museum (Pennsylvania, USA)

The Mütter Museum is the medical history museum of The College of Physicians of Philadelphia, located at 19 South 22nd Street in Philadelphia. Its galleries use anatomical specimens, medical instruments, models, preserved biological materials, and documented patient histories to examine the human body and the development of diagnosis and treatment. The institution remains an operating public museum as well as part of a larger medical-history research environment that includes the College’s Historical Medical Library.

From Thomas Dent Mütter’s Teaching Collection to the College Museum

The Museum developed from the teaching collection of surgeon and medical educator Thomas Dent Mütter. When the College accepted his collection and financial endowment, the arrangement carried specific obligations: the College was to employ a curator, preserve and enlarge the collection, support lectures, and provide a fireproof building for it. Those requirements tied the collection to medical education rather than treating it simply as an assemblage of anatomical curiosities. ^[Ref-3]

1. 1858–1859: Mütter arranged for his teaching collection of more than 1,700 objects and specimens, along with an endowment, to pass to The College of Physicians of Philadelphia.
2. 1863: The first purpose-built home for the Museum was completed at Locust and 13th Streets.
3. 1874: The Museum acquired Josef Hyrtl’s collection of 139 human skulls.
4. 1909: The College moved to 19 South 22nd Street, bringing the Museum and its original display cases to the present building.
5. 2025: The College announced updated policies governing the acquisition, care, exhibition, photography, and interpretation of human remains.

The survival of the original cases matters to the way the collection is encountered. The galleries retain elements of the older cabinet-museum model, where numerous specimens and objects can be examined together rather than being distributed through a modern science-center format dominated by interactive installations.

Anatomy, Pathology, Instruments, and Medical Material Culture

The Museum’s holdings cover a long period, from material dated to the seventh century BCE through modern collecting, although the institution states that much of the collection dates from the mid-19th through early 20th centuries. Its scope is broader than preserved anatomy alone. ^[Ref-4]

• Osteological material: Skeletons, skulls, and other preserved bone specimens document anatomy, disease, physical variation, and the history of anatomical study.
• Wet and dry specimens: Preserved human and non-human biological materials allow the Museum to document medical conditions and historical approaches to pathological anatomy.
• Medical instruments: Surgical and diagnostic equipment records how physicians attempted to examine, treat, and operate on patients in different periods.
• Models and teaching aids: Wax, plaster, papier-mâché, and other models demonstrate how anatomy and medical procedures could be taught when direct access to human specimens was limited.
• Pharmaceutical and medical objects: Medicines, containers, equipment, and associated material culture place clinical practice within the everyday history of health care.
• Personal and documentary material: Some collections preserve information about the individuals connected with specimens, allowing an anatomical object to be read alongside a documented medical or personal history.

The Museum’s public collections portal provides records and images for many holdings, while the physical collections contain material that has not all been digitized. This distinction is important for research: an online search can identify relevant material, but it does not represent everything that may be available through a formal research request.

Four Collections That Show Different Uses of Medical Evidence

Several long-term displays illustrate how differently the Museum’s material can function. Some began as anatomical teaching collections, while others preserve clinical records, individual medical histories, or physical evidence that later examination caused researchers to reinterpret.

Harry Eastlack and Carol Orzel

A permanent exhibition also presents the medical histories of Philadelphia residents Harry Eastlack and Carol Orzel, both of whom lived with fibrodysplasia ossificans progressiva, or FOP. Their skeletons document a rare disorder in which connective tissues progressively form bone outside the normal skeleton. Both cases have an unusually direct connection to education: Eastlack requested that his body be used to advance understanding of the disease, while Orzel was an active advocate for medical education and chose to donate her skeleton to the Museum. ^[Ref-9]

Human Remains, Provenance, and Current Display Policy

Human remains are central to the Mütter Museum’s identity, but the institution now places explicit emphasis on stewardship, provenance, and the individuals represented by those remains. Following a review and community-engagement process, the College announced updated policies in August 2025 governing their acquisition, exhibition, photography, and use. The Museum states that it will continue displaying human remains while working to provide greater context about their histories and provenance. ^[Ref-10]

This policy has practical consequences for visitors as well as collections staff. The skeletal and wet specimens in the galleries are preserved material from real people, while other displays may instead be life casts or models made from materials such as wax, plaster, or papier-mâché. Treating those categories accurately is necessary for understanding what a visitor is actually seeing.

The Museum Within the College of Physicians

The Mütter is not a stand-alone institution detached from Philadelphia’s medical history. It is operated by The College of Physicians of Philadelphia, a nonprofit institution founded in 1787 by physicians seeking to advance medical knowledge. Museum collections therefore sit beside the College’s library, archives, educational programs, professional fellowship, and other work concerned with medicine and public health.

This relationship separates the Museum from attractions that present medical specimens primarily as spectacle. Its material remains connected to an institution that preserves historical medical records and makes collections available for scholarly work. The same building brings public exhibition, object collections, rare books, archives, and research services into one institutional setting.

Visiting the Galleries at 19 South 22nd Street

The physical nature of the collection affects how a visit should be planned. The Museum advises that 18 percent of its collection consists of human remains and recommends the galleries for children age 10 and older, while leaving the decision to parents or guardians. Strollers, luggage, and large bags are not permitted because many gallery passages are narrow and the historic cases require protection. ^[Ref-11]

Visitors using wheelchairs or other mobility devices can enter through the accessible entrance on Van Pelt Street. The lower-level galleries are served by an elevator, although visitors need assistance from Security to use it. The Museum states that the elevator accommodates wheelchairs up to 32 inches wide, and manual wheelchairs are available at the admissions desk on a first-come, first-served basis. Personal Care Assistants accompanying a paying visitor receive complimentary admission under the Museum’s accessibility policy. ^[Ref-12]

The Museum does not operate its own public parking lot. Its location is nevertheless connected to several Philadelphia transit systems: SEPTA trolley service stops near Market and 22nd Streets, while 30th Street Station provides Amtrak, Regional Rail, and Market-Frankford Line connections within walking distance of the Museum.

Research Beyond the Public Displays

The collections can be used for research rather than only viewed in exhibition cases. The Museum and Historical Medical Library accept in-person research requests by appointment, and the Museum’s research portal can be used to identify digitized collection records before contacting staff. Access to sensitive or fragile material may be limited according to condition and collections requirements. ^[Ref-13]

The Historical Medical Library extends the research context considerably beyond the objects displayed in the Museum. Established in 1788, it preserves early printed medical books, more than 400 incunabula printed before 1501, institutional archives, correspondence, case books, student notebooks, photographs, and other sources documenting the history of medicine and medical practice. Catalogs, archival finding aids, digital images, and digitized volumes provide additional routes into these holdings. ^[Ref-14]

For students of medical history, anatomy, material culture, museum collections, or the history of clinical practice, the connection between the galleries and these research holdings is one of the institution’s most useful features. A displayed specimen can be part of a much larger documentary record involving physicians, patients, teaching practices, instruments, books, and archival material preserved by the same parent institution.
