1980s Set of 10 Model 811 Prague Chairs by Josef Hoffman for Stendig / Thonet

The Austrian architect Josef Hoffmann was a central figure in the evolution of modern design, and a leader in an aesthetic movement born in Europe in the late 19th century that rejected florid, extravagant ornamentation in favor of a new emphasis on simplicity of line.

As a founder of the Vienna Secession — a union of artists and designers determined to upend Austria’s artistic conservatism — and later, a founder of the turn-of-the-century Wiener Werkstätte (in English: the Viennese Workshops), a design cooperative that produced superbly crafted furniture and housewares, Hoffmann was a pioneering practitioner of what would become a fundamental principle of modernism: that good design is a way of life.

Hoffmann came of age amidst a shift in the culture of the applied arts, as a conservative order that looked only to the past for inspiration was pushed aside. But what, exactly, would replace that order was in question — and Hoffmann’s career embodies the developing patterns of design’s new spirit. His architectural work reflects his time as a student of the Vienna architect Otto Wagner, who disdained excessive decoration and employed new materials such as steel girders and reinforced concrete to create buildings with airy, open interiors full of light.

As a designer of furniture and interiors, Hoffmann was consistently open-minded about the aesthetics he explored. He was an early adherent of the flowing, organic forms of the Art Nouveau design movement that began to flourish in the late 1880s — but by the opening of the Wiener Werkstätte in 1903, Hoffmann’s designs embraced the beauty of geometry in pieces that feature grids and angular forms.

Hoffmann’s greatest works reflect his ability to combine seemingly conflicting design visions into coherent wholes. His architectural masterpiece, the Stoclet Palace in Brussels, has an exterior that groups together simple geometric forms and spacious interiors marked by subtly naturalistic design details that lend rooms an air of charm and geniality.

Hoffmann’s signature furniture design is an adjustable lounge chair — the Sitzmaschine (1905) — that marries a curving frame with square and rectangular back- and side rests. This piece, like so many others by Hoffmann, reflects a groundbreaking, forward-thinking appreciation for the union of different looks and sources that marks the best of interior design in our own day. Moreover, items offered on 1stDibs — which range from enameled silver jewelry, to silver flower vase baskets and other decorative objects, to sofas, lighting pendants and sconces — testify to the astonishing breadth of Hoffman’s creative pursuits. He was truly a giant of design.

Austrian architect and furniture and fabric designer Josef Frank was a leading voice for a gentle, humane modernism. His advocacy of warm, comfortable, eclectically styled environments was highly influential in his adopted country of Sweden, and it’s now widely regarded as a harbinger of the backlash against doctrinaire modernism and the embrace of the homespun that occurred in the late 1960s.

The son of a successful Viennese textile manufacturer, Frank studied architecture at Vienna University of Technology, graduating in 1910. From the first years of his practice, he marched counter to the orderly, symmetrical architectural layouts and decors prescribed by contemporaries such as Adolf Loos.

Frank drafted rooms of varying shapes and called for flexible interior-design arrangements. His furniture pieces are light and easy to move — and his chairs are always made of wood, most often with lushly curved steam-bent arms and slatted backs. Frank openly loathed the tubular steel furnishings and “machine for living” aesthetic promoted by Le Corbusier and Ludwig Mies van der Rohe and other Bauhaus principals. “The home must not be a mere efficient machine,” Frank once said. “It must offer comfort, rest and coziness…. There are no puritan principles in good interior decoration.”

Frank — who was Jewish — sensed the dire implications of the rise of Nazism in Germany and Austria, and in 1933 he moved to Stockholm with his Swedish wife, Anna. He became the design chief for the furnishings maker Svenskt Tenn and found a perfect match culturally for his brand of simple, relaxed and bright creations. Like many modernists — notably Charles and Ray Eames and Alexander Girard — Frank had a deep love of folk art, which influenced his designs for a wide array of colorful, richly patterned upholstery fabrics, many based on the classic “Tree of Life” motif.

In all his designs, Frank took inspiration from a broad variety of sources. In his furniture, one can discern traces of Asian patterns, Rococo, Italian Renaissance, Scandinavian handicrafts and even Chippendale pieces. As such, the work of Frank — the friendly modernist — is at home in any type of décor.
