Set of Six Handkerchief Chairs by Massimo Vignelli for Knoll

Massimo Vignelli and Lella Vignelli’s legacy can be seen everywhere in the logos of Bloomingdale’s, Ford and American Airlines, among others. In addition to their work in branding, they were prolific creators of modernist home furnishings, products and interiors, and the duo’s collaborations, which span 50 years, have left a profound mark on design and wider visual culture.

After meeting in Italy, Lella (1934–2016) and Massimo (1931–2014) began working together in 1961 and a decade later formed Vignelli Associates in New York. A self-described “information architect,” Massimo was committed to streamlining complex ideas into clear, visually arresting forms. (Witness the graphic identity that he cocreated with Bob Noorda for the New York City Transit Authority as well as his influential 1972 subway map.) The Vignellis’ most recognizable piece, for example, may be the Handkerchief chair, a stackable office chair made of compression-molded plastic that has the look of a cloth floating in air. It was created for Knoll in 1983 after they designed the brand’s logo.

Evidence of the couple’s influence can also be found in their Saratoga line (1964), the first collection of lacquered furniture, which helped herald in the trendy “glossy” look of the decade (and beyond). When the Vignellis created the Poltrona Frau Interview chair in 1988 for an Italian television station, it became widely sought after, “which goes to show you the power of the TV media,” the couple once said. Much like their elemental graphic designs, the Kono (1984) and Pisa tables (1985) — both created for Casigliani — cull the form of the table down to geometric shapes.

Vignelli furniture is often labeled as Massimo Vignelli’s alone, though he fought to have Lella recognized for her work, even throwing away magazines that neglected to give her due credit. As he wrote of their lifelong collaboration in his book Designed By: Lella Vignelli: “It is not holding a pencil with four hands that makes a partnership; it is sharing the creative act and exercising creative criticism which is reflected in the end result.”

As a company that produced many of the most famous and iconic furniture designs of the 20th century, Knoll was a chief influence in the rise of modern design in the United States. Led by Florence Knoll, the firm would draw stellar talents such as Ludwig Mies van der Rohe and Eero Saarinen into its compass. Their work would help change the face of the American home and office.

The company was formed in 1938 by the German immigrant Hans Knoll. He first worked with his fellow ex-pat, the Danish designer Jens Risom, who created furniture with flowing lines made of wood. While Risom served in World War II, in 1943 Knoll met his future wife, Florence Schust. She had studied and worked with eminent emigré leaders of the Bauhaus, including Mies, Walter Gropius and Marcel Breuer. She won Knoll over with Bauhaus notions of industrial arts, and an aesthetic that featured flat and tubular metal frames and angular forms. When Hans died in a car crash in 1955, Florence Knoll was appointed head of the company. It was as much through her holistic approach to design — a core division of the firm was dedicated to planning office systems — as Knoll's mid-century modern furnishings themselves that she brought about the sleek and efficient transformation of the American workplace.

Today, classic Knoll furnishings remain staples of modern design collections and decor. A history of modern design is written in pieces such as the elegant Barcelona chair — created by Mies and Lilly Reich — Saarinen’s pedestal Tulip chair, Breuer’s tubular steel Wassily lounge chair and the grid-patterned Diamond chair by Harry Bertoia.

As you can see from the collection of these designs and other vintage Knoll dining chairs, sofas and tables on 1stDibs, this manufacturer's offerings have become timeless emblems of the progressive spirit and sleek sophistication of the best of modernism.
