Handkerchief Chairs by Massimo and Lella Vignelli for Knoll International, 1980s, Set of 4

For over 50 years, Italian-born husband-and-wife team Massimo and Lella Vignelli collaborated on a variety of now iconic design projects spanning the product, print, interior, exhibition, and industrial arenas.

Massimo Vignelli was born in Milan in 1931. He studied architecture at the Accademia di Belle Arti di Brera in Milan from 1948 to 1950, before going on to study at both the Politecnico in Milan (1950–53) and the University of Venice (1953–57). While still a student, he designed lighting for renowned Murano glassmaker Venini.

Lella Vignelli (née Valle) was born in Udine, Italy in 1934. She studied architecture at the Massachusetts Institute of Technology (MIT) in Cambridge from 1955 to 1958, and, before returning to Italy, worked as a junior designer for Skidmore, Owings & Merrill. In 1962, she graduated with a degree in architecture from the University of Venice.

Having married in 1957, the pair established the Lella and Massimo Vignelli Office of Design and Architecture in Milan in 1960, focusing on office accessories, home products, graphics, and furniture. The studio’s clients included Pirelli and Olivetti, among others. In 1965, the Vignellis moved to Chicago and founded, along with six other designers, Unimark International (1965–71), which specialized in corporate graphics. Clients included the likes of American Airlines, Knoll, Bloomingdales, Ford, and Saks Fifth Avenue. Notably, Massimo’s prolific print work championed the Helvetica typeface, encouraging its eventual widespread popularity in the US. In 1971, the couple established Vignelli Associates (known from 1978 on as Vignelli Designs) in New York. They continued to work together until Massimo’s passing in May of 2014.

The Vignellis can be credited with helping to bring contemporary Italian design to the US. Their shared aesthetic celebrates balance, elegance, and simplicity, and embraces the notion that a designer should be able to design anything and everything. Notable projects include, among others, the stackable Knoll Handkerchief Chair (1982–87); colorful, molded melamine Heller Stacking Dishes (1964); and the 1972 New York City subway map. In addition to their design work, both have taught, lectured, written, and served on a variety of juries and boards throughout their careers. Their work has been exhibited internationally in a variety of exhibitions, including, in 1980, a retrospective at New York’s Parsons School of Design. In 1982, the Vignellis were awarded the AIGA Gold Medal. In 2008, the couple donated their complete design archive to the Rochester Institute of Technology in upstate New York; the archive is now housed in a 2010-erected building of their own design, the Vignelli Center for Design Studies.

Hans Knoll was born in 1914 in Stuttgart, Germany, into the successful manufacturing family behind Walter Knoll & Co. Early-20th-century Germany was an epicenter of modernist design theory—most notably expressed in the products and practices of the Deutscher Werkbund association of artists, architects, designers, and industrialists, as well as the influential Bauhaus school—which advocated for design rooted in the principles of rationality, functionalism, and mass production. This milieu had a profound influence on Hans and inspired him to produce furniture for the new age. In 1937, after a stint in London, he moved to the United States and brought his modernist vision with him.

Florence Knoll (neé Schust) was born in Saginaw, Michigan in 1917 and from an early age exhibited a strong interest in architecture. After graduating from the Kingswood School for Girls in 1934, she moved across campus to the newly formed, Bauhaus-inspired Cranbrook Academy of Art to study architecture under recent émigré, Finnish architect Eliel Saarinen. There she befriended future design luminaries Charles Eames and Eero Saarinen. She went on to Columbia University’s School of Architecture to study town planning. In 1937, she apprenticed under former-Bauhaus professors Walter Gropius and Marcel Breuer in Cambridge, Massachusetts, and a few years later, enrolled at the Illinois Institute of Technology, where German architect Ludwig Mies van der Rohe became a life-long mentor to her.

In 1938, Hans Knoll established The Hans G. Knoll Furniture Company as a furniture exporter in a small space on East 72nd Street in New York City. As the company quickly grew, it evolved into a manufacturing business. In 1941, he opened his first plant in a former dance hall in East Greenville, Pennsylvania and hired Danish designer Jens Risom, who eventually helped him develop the first, original Knoll furniture designs. That same year, Hans met Florence on an interior design project and, recognizing her exceptional taste and eye, hired her to bring in business with architects and interior designers and, later, to provide in-house planning and interior design expertise for a growing corporate clientele. In 1946, Hans and Florence married and renamed the company Knoll Associates. That same year, the Knolls formally established the Planning Unit, solidifying the company’s role in the design of interior spaces. In 1951, Knoll International was launched as the German and French arms of Knoll, producing Knoll designs for the European market. Sadly, Hans died in a tragic car crash in 1955, but Florence remained actively involved until she retired in 1965.

Knoll’s signature pieces include Breuer’s Wassily Chair (1925), Mies van der Rohe’s Barcelona Chair (1929/1948), Harry Bertoia’s Diamond Chair (1952), Eero Saarinen’s Tulip Armchair (1957), as well as Florence‘s own furniture collection developed through the 1950s. Knoll’s impressive catalogue includes a who’s-who list of midcentury modern and contemporary design figures, including Jens Risom, Alexander Girard, George Nakashima, Isamu Noguchi, Richard Schultz, Warren Platner, Charles Pollock, Andrew Morrison & Bruce Hannah, Vignelli Associates, Richard Sapper, Maya Lin, Frank Gehry, and Rem Koolhaas. As of this writing, Knoll’s most recent collaboration is with David Adjaye, who designed the Washington Collection for Knoll and the Adjaye Collection for KnollTextiles. Today, the company is particularly focused on meeting the evolving needs of the 21st-century workplace.

In 2011, Knoll received the National Design Award for Corporate and Institutional Achievement from the Cooper Hewitt, Smithsonian Design Museum in New York. The award recognized Knoll’s legacy in American modern design and the company’s commitment to promoting the relationship between good design and quality of life. Knoll designs can be found in the permanent design collections of institutions around the world, including more than 30 acquired by New York’s Museum of Modern Art.
