Cooper Hewitt, Smithsonian Design Museum (New York, USA)

Cooper Hewitt, Smithsonian Design Museum is a Smithsonian museum at 2 East 91st Street in Manhattan, housed in the former residence of Andrew Carnegie. It is the only museum in the United States devoted exclusively to historical and contemporary design, and its holdings extend from centuries-old textiles and works on paper to industrial products, graphic design and digital works. More than 215,000 design objects across roughly 30 centuries place the museum’s subject far beyond furniture or decorative objects alone. ^[Ref-1]

The institution combines several functions that are usually less visible to a gallery visitor. Its public exhibitions are supported by curatorial departments, study rooms, a design research library, digital collection records, educational programs and graduate-level teaching. That combination continues an idea present at the museum’s creation: design objects were meant to be studied, compared and used as sources for new work rather than simply viewed from a distance.

A Working Laboratory Before It Became a Smithsonian Museum

Sarah and Eleanor Hewitt established the Cooper Union Museum for the Arts of Decoration in 1897 inside the Cooper Union for the Advancement of Science and Art, founded by their grandfather Peter Cooper. Their model drew partly from the Musée des Arts Décoratifs in Paris. The New York museum was conceived as a practical working laboratory where students, designers and members of the public could examine material directly and use collections as part of design education. ^[Ref-2]

The museum’s later history involved both institutional rescue and relocation. Cooper Union announced plans to discontinue the museum in 1963, prompting an organized campaign to keep the collection together. An agreement transferring the museum and library to the Smithsonian was signed in 1967, judicial approval followed, and the formal transfer took effect in 1968. The museum eventually moved into the Carnegie Mansion and opened there to the public in 1976. ^[Ref-3]

1. 1897: Sarah and Eleanor Hewitt open the Cooper Union Museum for the Arts of Decoration as a study resource for design.
2. 1963: Cooper Union announces its intention to disband the museum, leading to a campaign to preserve the collection.
3. 1967–1968: The museum enters the Smithsonian through an institutional transfer completed in 1968.
4. 1976: The renovated Carnegie Mansion opens to the public as the museum’s new home.
5. 2014: Following a major campus renovation, the museum reopens under its present name, Cooper Hewitt, Smithsonian Design Museum.

Five Departments Stretch From Ornament Drawings to Digital Code

The collection began with a strong decorative-arts orientation, including textiles, wallcoverings, furniture, metalwork, drawings and prints. It has since expanded into product, graphic, industrial and digital design while retaining those earlier materials. The permanent collection now contains more than 215,000 objects and spans about 30 centuries; the museum also makes its digitized collection available online for study. ^[Ref-4]

Its present collecting structure is divided into five curatorial departments. The addition of Digital in 2023 was the first entirely new collecting department created by Cooper Hewitt in more than 125 years, formally extending museum collecting into born-digital work rather than treating digital design only as exhibition material. ^[Ref-5]

• Drawings, Prints and Graphic Design: Architectural and interior drawings, ornament studies, posters, graphic work, industrial-design drawings and other works on paper document both finished ideas and the process that precedes production.
• Product Design and Decorative Arts: Furniture, ceramics, glass, metalwork, jewelry, woodwork and industrially produced objects allow the museum to examine how form, material, manufacturing and use interact.
• Textiles: Historic and modern textiles provide evidence of weaving, printing, pattern, material experimentation, fashion and interior use across different periods and regions.
• Wallcoverings: Wallpaper and related material preserve changing approaches to surface pattern, printing technology, domestic interiors and commercial production.
• Digital: The department collects and cares for born-digital design, addressing works whose behavior, code or digital environment may be inseparable from the object itself.

This breadth changes how the collection can be read. A drawing may sit at the beginning of a design process, a prototype may reveal testing and revision, and a manufactured object may show how an idea reached actual users. Digital work adds another problem: preservation may require maintaining software, data or interaction rather than safeguarding only a physical material.

Works on Paper and Books Form a Second Research Layer

Cooper Hewitt’s public galleries represent only part of its research value. The Drawings, Prints & Graphic Design department holds more than 147,000 drawings and prints dating from the Renaissance to the present. Architectural designs, decorative-arts studies, interior schemes, ornament, jewelry designs, textile designs, graphic work and industrial-design drawings can be consulted through the Drue Heinz Study Center for Drawings and Prints and the Henry Luce Study Room for American Art by appointment. ^[Ref-6]

The library’s holdings also show how wide design research can become. Its stated strengths include more than 1,000 World’s Fair items, over 1,700 pop-up and movable-book titles, material on architecture and interior design, sample books, trade literature and specialized archival collections. About 30 percent of the library collection, including all rare books, is maintained on site in the Miller-Fox Townhouses next to the mansion. ^[Ref-7]

Andrew Carnegie’s 64-Room House Became Part of the Collection Experience

The museum and its building began as separate stories. The Carnegie Mansion was constructed from 1899 to 1902 for industrialist Andrew Carnegie, his wife Louise and their daughter Margaret. Babb, Cook & Willard designed the 64-room residence with the character of an English Georgian country house. Its large garden was possible partly because Carnegie chose a site farther north than the fashionable residential concentration of his era.

The house itself incorporated technologies that make it relevant to a design museum. Cooper Hewitt identifies it as the first private residence in the United States built with a structural steel frame and as one of New York’s early residences with an Otis passenger elevator. Its mechanical systems also included central heating and a small rail system in the cellar for moving coal to the boilers. ^[Ref-8]

Conversion to museum use did not end the building’s evolution. During the 2011–2014 renovation, exhibition space increased from about 10,000 to 17,000 square feet while the project restored historic elements and introduced new gallery, lighting, visitor and collections infrastructure. The work extended beyond the mansion into the museum campus, including the neighboring Miller-Fox Townhouses. The campus received LEED Silver certification in 2015.

Design Across Time Brings More of the National Collection Into View

A recurring challenge for a collection exceeding 215,000 objects is that only a fraction can be displayed at one time. Cooper Hewitt addressed that issue directly in 2026 with Design Across Time: Exploring the Smithsonian’s Design Collection, a long-duration presentation occupying the first-floor galleries of the Carnegie Mansion. The installation opened June 26, 2026 with more than 125 works and is planned as a two-year presentation with object rotations during its run. ^[Ref-9]

Rather than arranging the selection as a simple chronological progression, the galleries group works through approaches designers use while developing ideas. Product and graphic design, fashion, textiles, furniture, wallcoverings, architecture and digital design can therefore appear in conversation across different dates and places. Some objects come from storage, while others are recent acquisitions receiving an early public presentation.

For a visitor trying to understand Cooper Hewitt’s identity, this installation is useful because it makes the relationship between departments more visible. A museum founded around decorative arts now preserves sketches, manufactured products, communication systems, fashion, digital objects and other evidence of how design decisions move from concept to use.

Teaching and Public Design Programs Extend Beyond the Galleries

Education has remained connected to Cooper Hewitt’s collecting purpose since the Hewitt sisters opened their study museum. Today the museum runs lectures, conversations, workshops and other design programs alongside its exhibitions. It also works with Parsons School of Design on the Master’s Program in the History of Design and Curatorial Studies, which places graduate teaching on the museum campus and gives students access to collections and museum departments.

The National Design Awards, launched by Cooper Hewitt in 2000, add another public-facing part of the museum’s work. The program recognizes work across multiple design fields, while associated programming brings practicing designers and their ideas into educational settings. Together with the online collection and research facilities, these activities mean Cooper Hewitt operates as more than a sequence of exhibition rooms. ^[Ref-10]

Visiting the Museum on East 91st Street

The main museum entrance is at 2 East 91st Street between Fifth and Madison Avenues. The museum is open daily from 10:00 a.m. to 6:00 p.m., except Thanksgiving Day and Christmas Day. Regular admission is $22 for adults, $16 for visitors age 62 and above, and $10 for students with identification and visitors with disabilities; admission is free for visitors age 18 and under. The museum also lists pay-what-you-wish admission from 5:00 to 6:00 p.m. daily.

The accessible route enters through the garden on East 90th Street. Wheelchairs are available on a first-come, first-served basis, while current exhibition resources can include sensory maps, large-print labels, object descriptions and audio material. Public tours are offered, and the museum provides disability-focused tours and educational programs through its access programming.

Several everyday gallery policies are stated directly by the museum. ^[Ref-12]

• Photography: Non-commercial photography without flash is permitted; tripods, monopods and selfie sticks are not permitted.
• Sketching: Visitors may sketch in the museum, but ink and markers are not permitted.
• Bags: The museum asks visitors to leave large bags and oversized umbrellas at home.
• Strollers: Compact strollers are permitted.
• Food and drink: Food and beverages are not permitted inside museum galleries.
• Animals: Pets are not permitted on the campus; service animals are allowed.

Cooper Hewitt is especially useful for visitors who want to connect finished design with the evidence behind it: drawings, prototypes, printed material, manufacturing, textiles, digital work and research literature. Its institutional character still reflects the museum created in 1897, but the definition of what belongs in a design collection has continued to expand.
