Winterthur Museum, Garden & Library has a secret: Scattered throughout its lounges, libraries, laboratories, and offices are stashes of modern furniture that have as much of a story to tell about American design as the early American furniture the museum is famous for.

The pieces are on display July 28 in “Unity by Design: Midcentury Modernism at Winterthur.”

The exhibition looks at midcentury modern furniture to better understand it as an extension of Winterthur’s collection and mission -- to explore what it means when traditional meets modern. Midcentury modernism refers to the post‒World War II design movement that sprung from a desire for a new way of living. The mission was to depart from the past in order to foster a better-lived experience for the future.

Although Henry Francis du Pont’s desire to promote and preserve American antiques may seem to be at odds with the aesthetic, his interest in style and design was broad reaching and he was as enamored of the new American style as anyone.

When du Pont opened Winterthur Museum in 1951, his intention was to expand the interest in, and interpretation of, early American decorative arts. Yet, over 18 years, he worked with architects and designers on the construction of several auxiliary buildings on the estate -- an office wing and auditorium, a research library, conservation labs, and a visitor pavilion where the interior design presented a radically different look. From fixtures to furnishings, each of these spaces was designed in the midcentury modern style. Those furnishings -- more than 170 pieces -- are still in use at Winterthur.

“For many years, the midcentury buildings and furnishings at Winterthur were not understood, often moved to storage buildings, and considered an anomaly. People sometimes commented that H. F. du Pont would have hated this stuff.  As ‘Unity by Design’ reveals, he not only appreciated it, but helped pay for it,” said Jeff Groff, estate historian at Winterthur.

The exhibit features pieces by famous midcentury designers Ray and Charles Eames, Florence and Hans Knoll, and Eero Saarinen. Their designs for Knoll Associates and the Herman Miller Furniture Company set a new standard for modern living. It was the design choice for corporations, businesses and homes.

“Unity by Design” was curated by Carrie Greif, who will graduate from the Winterthur Program in American Material Culture in May 2019, as part of her graduate thesis work. In addition to creating this exhibit, Greif catalogued the midcentury modern furniture on the Winterthur estate.

Visitors are encouraged to explore the philosophy, construction, and branding of midcentury modern furniture by taking a seat and browsing catalogues that were available to consumers in the 1950s and 1960s, and by exploring photographs of Winterthur spaces furnished in midcentury style and sketches by the famous designers themselves.

“Unity by Design: Midcentury Modernism” at Winterthur is on display through July 28, 2019, in the Society of Winterthur Fellows Gallery.
