Setting the Table

By El Clauss, tour program assistant

When Henry Francis du Pont designed a dinner table setting, he always began with flowers. Several days before the party, his head gardener, Joseph Feliciani, would bring him cuttings from the garden so he could choose the centerpiece flower. Once that was decided, all other iterations of that flower would be removed from the house so as not to ruin the surprise. For my design, however, the flowers were the last piece I figured out.

When asked to create a setting that had an H. F. design feel, I wanted to connect the display to our Focus On: Ceramics Tour. I also wanted to highlight the different colors in the dining room—green, blue, yellow, and pink. Collaborating with Leslie Grigsby, senior curator of ceramics and glass, I discovered the charming green glass goblets. From there we chose from the wide array of items in the collection with the famille rose–patterned china, which is featured in the Focus on Ceramics tour.

Symmetry and balance were key elements of H. F.’s designs, which I also incorporated. Since he preferred to dine by candlelight, candle holders needed to be included. The two ladles I chose connect the outdoors with the indoors, as H. F. often did. One ladle’s handle features a basket of flowers, to represent the garden; the other shows an image of George Washington, to represent the collection.

H. F. purchased most of the blue linens from Marshal Fry, a prominent New York-based ceramist, teacher, and American impressionist painter, who turned to creating colorful linens for tablescapes in the early 20th century. As Maggie Litz notes in her article “The Politics of Placemats,” “In mid-twentieth-century America, Fry was who you called if you took entertaining seriously.”[1] The blue with dark blue borders set was chosen because it brings out the blue on the ceramics beautifully. Lastly, I worked with our head florist, Heidi Militana, to design the centerpiece, which is bursting with yellow roses and blue hydrangeas.

We hope visitors will agree that we have set a table fit for a du Pont. Come see the display in the Du Pont Dining Room on the Self-Paced House Tour and let us know if we captured H. F.’s penchant for a well-laid table.

H. F. du Pont’s Enduring Legacy: 5 Lessons in Timeless Design

By Allie Kochinsky | @TheGrandmillennialLifestyle

Winterthur Museum, Garden & Library stands as a testament to the vision and artistry of Henry Francis du Poet, a man whose influence on American design continues to captivate and inspire. His carefully curated estate is a treasure trove of antiques and decorative arts and a living lesson in the principles of timeless design. For those who adore history-rich interiors with lots of charm, du Pont’s legacy offers invaluable insights. Let’s explore five lessons from Winterthur that remain as relevant today as they were in du Pont’s time.

Embrace a Sense of Place

H.F. du Pont’s design choices were rooted—no pun intended—in his surroundings. He celebrated the landscape, incorporating nature into the estate’s interiors through botanical motifs, floral arrangements, and garden-inspired palettes. His thoughtful integration of indoor and outdoor spaces reminds us to honor the character of our own homes and draw inspiration from their natural settings.

Curate Intentionally

Every room at Winterthur tells a story, with each element meticulously chosen for its historical significance, craftsmanship, or personal meaning. H.F.’s approach teaches us the power of purposeful curation—selecting items that reflect our stories and values rather than following fleeting trends.

Layer

Du Pont was a masterful layerer of fabrics, wallpapers, and textiles. He seemingly effortlessly combined prints and patterns, creating dynamic and harmonious spaces. Modern design lovers experiment with layering today, using texture and pattern to add depth and personality to their rooms.

Celebrate Craftsmanship

Winterthur’s collection showcases the artistry of early American craftspeople, from intricate woodwork to hand-painted ceramics. Du Pont’s reverence for quality craftsmanship reminds us to seek out well-made, enduring pieces—whether antique or contemporary—that honor the hands and history behind them.

“Full many a flower is born to blush unseen…”

By Julie Hadsell, assistant librarian

“It is a truth universally acknowledged” that Jane Austen is a fan favorite for literature lovers all over the world.[1] Known for her beloved stories centering on themes of love, class, and social expectations set in Regency era England, Austen penned six novels that stand the test of time. In Emma, the last to be published before Austen’s death, our titular character experiences troubles and triumphs as she practices her matchmaking skills and perhaps even ends up with a match herself.

Austen lovers (also known as Janeites) may be interested to learn that the Winterthur Library holds a rare Austen in its collections. Published in Philadelphia in 1816 by Mathew Carey, this edition of Emma was the first Jane Austen work to be published in the United States, with only six known copies still surviving.[2] At the time, an American publisher reprinting a British work without informing the original publisher and author was fully legal, so we can assume Austen never knew about this first U.S. edition.  

What makes this edition so special? Mathew Carey immigrated to the United States from Ireland in 1784, and was a publisher, businessman, political writer, and self-proclaimed lover of novels and romances. In late 1816, he published Emma with a print run of 500 copies, almost a year to the day after the original edition was published in England. The book was credited on the title page to “the author of Pride and Prejudice,” though American readers did not yet have a reprint of Austen’s earlier works.  

Publishing Emma was a significant financial risk for Carey, and unfortunately no documentation exists to explain his decision to reprint the novel. At the time, Austen was an anonymous author never published in the States, and Carey and his printers took several economic shortcuts to save money on their risk. Some of these included condensing the novel into two volumes—it had originally been published in England in three—and using cheap paper and bindings. This, combined with sometimes rushed work assumed to be done by a young and inexperienced apprentice, likely explains why only six copies of the original 500 are known to still exist. In her book Reading Austen in America, Juliette Wells explains, “given the (understandably) low production values of Carey’s reprinted Emma, volumes would likely have disintegrated unless an owner cared enough to invest in having them rebound well.”  

Despite the shortcuts taken in its production, Winterthur’s copy of Emma, bound in calf leather and bearing the signature of E. I. du Pont, is in great condition. This lack of wear or significant markings sets Emma apart from other titles in the du Ponts’ personal libraries, and suggests that Emma was either not frequently read, or not enjoyed. Despite this possible lack of interest on the du Ponts’ part, E. I. du Pont was a contemporary of Mathew Carey and owned many of his publications. 

Interested in viewing Winterthur’s copy of Jane Austen’s Emma? Contact the Winterthur Library at reference@winterthur.org, but don’t delay. Emma will be traveling to the Morgan Library in New York for their exhibition A Lively Mind: Jane Austen at 250 from May through September 2025.

Caring for Your Collections: Caring for Your Family’s Gravestones

Left: Binh-An Nguyen lightly scrubbing Mary Campbell gravestone; Right: Binh-An Nguyen rinsing Mary Campbell gravestone.

This edition of Caring for Your Collections blog posts comes from Binh-An Nguyen, a student in the Winterthur/University of Delaware Program in Art Conservation. Binh-An specializes in preventive conservation, which focuses on slowing down deterioration of objects by setting up good rules and habits for how to care for them.

Why should I clean my family’s gravestones?

There are many reasons why you may want to clean your family’s gravestones. Cleaning can make the names and inscriptions more easily readable so you can find the gravestone more easily, now and in the future. Cleaning them is also a way to show care or respect for loved ones who have passed. 

What substances need to be cleaned from headstones?

Lichen, moss, or other living organisms that grown on gravestones are known as biogrowth. Biogrowth does not just exist on gravestones, it can exist on any surface with the right conditions—you may have noticed it on the roof of your house, for example.

Why is the biogrowth there?

Biogrowth loves moist environments. Rougher surfaces can cause moisture to be retained on the surface, creating ideal conditions for biofilms, lichens, etc. to grow. Gravestones with smoother, more polished finishes, on the other hand, may be less susceptible to biogrowth. Some gravestones use a combination of rough and smooth stones; you may notice that the biogrowth seems to prefer the rougher areas. Other environmental factors, such as location under a shady tree or in a rainy area, may also make a gravestone retain moisture, contributing to biogrowth. 

Left: Mary Campbell gravestone before cleaning; Right: Mary Campbell gravestone after cleaning.

What supplies do I need to clean a gravestone?

  • D/2 biological cleaner: A quart-sized bottle can clean many medium-sized gravestones
  • Clean water
  • Two hand pump sprayers or spray bottles, one for clean water and one for diluted D/2 biological cleaning solution. A garden sprayer may be more useful if you are cleaning many gravestones in one day.
  • Kitchen gloves
  • Nylon scrub brushes
  • Wooden or plastic popsicle sticks or spatulas
  • Orvus, a nonionic surfactant (optional)

Do I need to ask for permission before cleaning a gravestone?

If the gravestone is for someone in your immediate family and located in a cemetery, it is a good idea to ask the cemetery for permission or let them know what you are doing. 

If the gravestone is not for someone in your immediate family, make sure to also ask the immediate family or descendants of the person whose gravestone you want to clean. 

How do I clean my family’s gravestones?

We recommend doing this on a warmer day/week. If the weather is too cold, the water used to clean/rinse the gravestone may freeze and create cracks in the stone. Cleaning outside in the cold may not be enjoyable for you either! 

First, check the gravestone for any condition issues such as crumbling, separation of layers, “sugaring” (the stone crumbles when touched), etc., which may have affected the stability of the gravestone. If the gravestone is unstable, proceed with caution—cleaning it may cause further damage it. If it appears stable, then proceed to clean the gravestone using these steps:

  1. Trim any weeds from the base of the gravestone and brush away loose leaves or dirt.
  2. Wet the surface of the gravestone with clean water using the spray bottle or hand pump sprayer. Wetting the surface ensures that the cleaning solution stays on the surface and does not saturate the stone.
  3. Wearing kitchen gloves, apply a 1:1 solution of D/2 Biological Cleaner and clean water using a hand pump sprayer or spray bottle to saturate the surface. Allow the solution to sit for ~5 minutes and apply more as necessary to ensure the surface stays wet.
  4. Use a soft, nylon brush in slow circular motions to gently agitate the surface to allow the cleaning solution to saturate, and eventually remove, the biogrowth.
  5. Small amounts of Orvus can be applied directly to the stone and gently agitated with a soft, nylon brush to remove biofilm staining as needed. Rinse off the Orvus with clean water.
  6. Remove thicker lichen/biogrowth with wooden or plastic spatulas/popsicle sticks.
  7. Rinse the stone with clean water using a hand spray pump or spray bottle.
  8. Repeat steps 2–7 until desired cleaning level is achieved.

How often should I do this? 

Repetitive cleaning can result in damaging the stone by making it unstable or wearing it down, so we recommend doing this no more than once a year. Additionally, using the biocide cleaning solution too often could result in biogrowth forming a resistance to the cleaner. 

What are some things I should NOT do?

Do not use bleach; it can chemically interact with the stone and cause unintentional erosion/degradation.

Do not use metal scrapers or metal brushes to clean. They can scratch the stone surface. A good rule of thumb is “whatever is safe to clean the hood of your car is safe for the gravestone!”

How did they come to look that way? What can we learn from an object’s design and decoration? You’ll be ready to ask these same questions of other objects at Winterthur and beyond.

Bringing the “Afric-American Picture Gallery” to Life for the First Time

Bringing the “Afric-American Picture Gallery” to Life for the First Time: Winterthur Presents Exhibition Inspired by 19th-Century Essay by Black Educator and Journalist

WINTERTHUR, DE (February 5, 2025)—Almost Unknown, The Afric-American Picture Gallery, a new exhibition at Winterthur inspired by a 19th-century essay by William J. Wilson, a free Black journalist and educator, will be on view starting May 3, 2025. Interpreted by curator and historian Jonathan Michael Square, the exhibition presents—for the first time ever—the gallery imagined by Wilson.

Square has assembled drawings, paintings, sculptures, and objects from across the Winterthur collections to represent Wilson’s gallery and Black life in the United States and across the Diaspora. The exhibition is on view May 3, 2025–January 4, 2026.

Wilson’s essay “The Afric-American Picture Gallery” was published in 1859 under the pen name “Ethiop” as a series of installments in the Anglo-African Magazine. It describes an imagined gallery space that Ethiop has curated. He leads a tour of the artworks that both celebrate and critique the experience of free and enslaved Black Americans in the 19th century.

Square was invited to Winterthur to develop an exhibition that aligned with his scholarship and interests, drawing from Winterthur’s collection of nearly 90,000 decorative art objects. This multifaceted exhibition presents Wilson’s envisioned gallery and sheds light on stories that have long been overlooked in American museums and history.

“William J. Wilson’s essay is a curious text that challenges us to consider our past, reflect on our present, and imagine a more inclusive future,” said Square. “The objects visitors will see may not be the exact ones that Wilson described. Instead, they reflect my reading of the text and its relevance today as it is revealed in the Winterthur collection.”

Almost Unknown brings to light what Wilson’s essay described as an “almost unknown Gallery” by sharing objects from Winterthur’s collection. They include a silhouette attributed to Moses Williams, a modest trivet made in early America in the form of an African symbol, and copies of Harriet Beecher Stowe’s Uncle Tom’s Cabin and Phillis Wheatley’s Poems on Various Subjects, among others.

Jonathan Michael Square is assistant professor of Black Visual Culture at Parsons School of Design. He holds a Ph.D. from New York University, an M.A. from the University of Texas at Austin, and a B.A. from Cornell University. He was previously a lecturer in the Committee on Degree in History and Literature at Harvard University and a fellow in the Costume Institute at the Metropolitan Museum of Art. He curated Past is Present: Black Artists Respond to the Complicated Histories of Slavery at the Herron School of Art and Design (2022–23), Freedom from Truth: Self Portraits of Nell Painter (2019–20), Odalisque Atlas: White History as Told Through Art (2019–20), and Slavery in the Hands of Harvard (2019). He has been published extensively in academic journals and popular press. A proponent in the power of social media as a platform for radical pedagogy, Square founded and runs the digital humanities project Fashioning the Self in Slavery and Freedom.

A special house tour will highlight Square’s interpretation of the essay. In addition, the symposium Looking Back to the Future: Realizing “The Afric-American Picture Gallery” will take place at Winterthur on November 14 and 15, 2025. The symposium is designed to engage a diverse audience including educators at both college and secondary levels, museum professionals, scholars and enthusiasts of African American history, and the wider community. The keynote speaker will be Fred Wilson, curator of Mining the Museum, the seminal 1992 exhibition at what is now the Maryland Center for History and Culture. Wilson used that museum’s collections to confront and challenge perceptions about history, culture, and race, and the installation continues to influence scholars and museum professionals today.

Memorializing Friendship

By El Clauss, tour program assistant

Imagine you got a letter from your dear friend requesting a lock of your husband’s hair. Once you received it, you picked up a pair of scissors and cut not only a lock of his hair but also a lock of your own. After entwining them, you sent them off to your friend. Upon receiving the hair, your friend enclosed the locks in a brooch and engraved it with the story commemorating your friendship.

This probably sounds strange to us in the 21st century when we share photos with friends and family hundreds or thousands of miles away. However, prior to photography, exchanging locks of hair was a common token of friendship.

This is a true story about Mrs. Elizabeth Stoughton Wolcott of Connecticut. She was married to Oliver Wolcott Jr., the first auditor of the United States and the second treasurer after Alexander Hamilton. She wrote a letter to her close friend Martha Washington asking for a token of their friendship. It is said that Mrs. Washington instantly took her scissors and, with a happy smile, cut a large lock of her husband’s hair, added to it one of her own, and presented them to her “fair friend.” While we are unsure exactly when Mrs. Wolcott had a brooch made with the hair enclosed, it would have celebrated their friendship. However, when George Washington died it took on a new role: mourning jewelry.

Mourning brooch or pin
1797: Washington City, United States
Gold; Enamel on copper; Hair; Leather; Glass
Gift of Mrs. Paul Hammond 1962.0084

Mourning jewelry are unique personal adornments worn during a period of mourning to commemorate someone who died. Originating in the Middle Ages, this jewelry tradition grew in popularity and the designs changed greatly over the years. The jewelry could be a ring, a necklace, a cane handle, a watch fob, a bracelet, or a brooch and were worn by everyone regardless of gender. People gave them to close relatives and friends at a funeral, even leaving money in their will to pay for them. It was also common to use mourning jewelry to commemorate political figures like George Washington.

After Washington died, there was an outpouring of memorial pieces created to honor him. Winterthur features numerous examples in the collection, crafted in a wide variety of media. It can be argued that the brooch made for Mrs. Elizabeth Stoughton Wolcott, while perhaps not initially intended as mourning jewelry, would certainly have become one upon his death. Mrs. Wolcott would have felt honored not just by the token of friendship it represented but also by her ability to wear such an important piece of jewelry to honor the loss of President Washington. Thanks to her family treasuring the piece for generations before they donated it to Winterthur, we are now able to share in its rich history. In doing so, we memorialize not just George and Martha Washington but also their lasting friendship with the Wolcotts.

Caring For Your Collections: How to Protect and Preserve Your Family Heirlooms

Simple Tips for Home Care

You can take small steps at home to prevent damage and slow down deterioration of your cherished items. At Winterthur, and at other museums, we call this preventive conservation and have staff members dedicated specifically to that work. Preventive conservation is a lot like preventive medicine. Everything that is man-made or from nature decays; think of it as nature’s recycling plan. To protect and preserve the museum collection, our staff works to slow the rate of that decay by managing things like insects and pests, light exposure, and the environment via heating and air conditioning. Here are some tips that you can use at home:

1. Housekeeping

Good housekeeping is an important part of protecting items that you want to last. Cleaning inside includes regular dusting and vacuuming, and dry-cleaning fine clothes after use and before storage. Outside, cleaning gutters and downspouts to prevent leaks can all help. Dust holds moisture, which can rust metals and encourage mold growth.

2. Pest Control

Insects like dark, undisturbed spaces. If you clean regularly, you’ll probably spot early signs of an infestation, like insect droppings, which may just look like dust. If pests are eating your items, a thorough vacuuming can help. For example, carpet beetle larvae like to hide in cracks where hair and skin particles collect, so you may notice that your carpet has damage that follows the pattern of the flooring. For items that can withstand high heat, place them in a black trash bag and leave them in your car trunk while parked in direct sunlight for several hours to kill any pests.

3. Storage

We don’t recommend storing objects in attics or basements because it’s difficult to maintain a stable environment. Basements have issues with moisture and can flood, and attics can have seasonal temperature extremes; too cold temperatures can cause shrinking and cracking, while temperatures that are too hot can cause swelling and warping. Also, temperature and humidity work hand in hand and can cause chemical reactions and encourage mold or insect growth. We recommend storing cherished items in spaces that you live in and use.

4. Record Keeping

Write down the history of your items—who gave them to you, who is in the photos, and why they are important. This helps preserve their significance and keeps the information safe for future generations. Be sure to back up digital records and print copies for long-term use.

5. Storage Methods and Materials

Museum-quality storage materials are often called archival, acid-free, or buffered, among other names. They can be expensive for homeowners, but you can use everyday items you already have instead. For example, undyed/unbleached cotton pillowcases can protect a quilt, and rolled towels can be used to store a rolled carpet. If you need a more rigid storage method for rollable items, use a poster tube covered in aluminum foil, which acts as a barrier against moisture.

6. Light Protection

We all know that ultraviolet light is bad; it causes sunburn and can accelerate fading on some materials. Regular visible light, the light we use to see, can also cause slow, cumulative damage. It may take years to notice the subtle changes. To protect sensitive items like basketry and wood, textiles, and works on paper, avoid displaying them in direct sunlight. Use curtains, shades, or window films (replace every 15 years) to limit exposure to harmful light. You may also want to have covers made for your framed object so that when you aren’t enjoying the work and displaying it, it’s completely covered.

We want you to get a behind-the-scenes look at the fascinating world of conservation and inspire you to care for your own cherished items. 

Hazardous Objects

Why would someone collect things that are hazardous, you might be wondering. Most don’t do it intentionally. During the 19th century, advances in manufacturing led to the use of more hazardous substances. So, some objects are dangerous on their own because of the materials that they are made from. Others become risky over time as their materials degrade.

Common objects that could be hazardous include:

  • Firearms: These may still contain explosives and be dangerous.
  • Tin and mercury amalgam mirrors: Over time, these can release liquid mercury.
  • Lead objects: Handling lead items can leave behind harmful residues.
  • Arsenic green: This colorant, often found in book cloth and historical papers, can turn into a powder that’s hazardous when touched.
  • Uranium glass: This glass releases small amounts of radiation.
  • Dyed or printed textiles: These may contain harmful chemicals like arsenic, lead, and chromium from their production process.
  • Wool and other animal-based fibers: If they were treated with pesticides, harmful residues can remain on the material, which can be transferred to your hands and skin.

In addition, organic materials like textiles, feathers, fur, and plants are sometimes treated with pesticides that contain heavy metals or solvents, adding another layer of risk. Even objects that seem safe might be dangerous due to contamination, such as leather bags that may contain lead shot from use.

How to determine if an object is hazardous:

To determine if an object is hazardous, there are several signs to look for, even if you don’t have access to special equipment.

  • Condition of Organic Objects: If objects like textiles, wool, feathers, or botanical items are in perfect condition with no signs of pest damage, they may have been treated with  pesticides. The presence of a strong smell could mean that the object has been treated to keep pests away.
  • Mirrors: If you have a mirror from the 19th century or earlier, check for a blue-gray hue and signs of fading reflection. This could mean it was made with a tin/mercury amalgam, which can release mercury droplets over time. Mirrors made after 1850 typically do not contain mercury.
  • Vibrant Dyes: Some older textiles, especially those in bright colors or certain shades of green, might contain arsenic, lead, or chromium. These substances are usually bound to the fabric, so they are generally safe to touch, but it’s recommended to wear gloves as a precaution. Books made with arsenic-based dyes can sometimes be identified visually.

What to do if you suspect a hazardous object:

If you think you have a hazardous object in your home, don’t worry! Most objects can be handled safely with a few precautions:

  • Keep it out of reach of children or pets: If the object is accessible to children or animals, move it to a safer place, such as a locked cabinet or box, and label it as hazardous.
  • Protect yourself: Wear gloves when handling any potentially hazardous organic objects, as they may have been treated with chemicals. If you don’t have gloves, wash your hands thoroughly before and after handling.
  • Firearms: If you have a historic firearm, have it checked by your local police or a firearms expert to make sure it is not loaded or dangerous.
  • Repurposing: If you plan to reuse these materials for something else, think about how they will be handled and whether they could pose a risk.
  • Consult a conservator: You can bring your objects to Winterthur’s Conservation Clinic, which is held in September, October, November, December, March, and April, for a professional assessment of their safety.
