Rosewood & Bronze Dining Table by Warren Platner for Knoll, 1960s

American architect and interior designer Warren Platner was born in Baltimore, Maryland in 1919. Platner attended Cornell University, graduating with a degree in architecture in 1941. Shortly after, he began working with legendary architects Raymond Loewy and I.M. Pei from 1945 to 1950, and with Eero Saarinen from 1960 to 1965. During this time he was part of the design process of many historically important projects including the Dulles International Airport, in Washington, D.C., the Repertory Theater at Lincoln Center, and several dormitories for Yale University. Platner joined Kevin Roche’s firm as the head of interior design, becoming more involved with interior and industrial design, as he believed that the essence and character of a building’s design should come from within.

In 1967, having gained a wealth of expertise and knowledge from working for architect-design luminaries, Platner decided to open his own firm, Platner Associates. Not limiting itself to architecture, it also experimented in furniture design, lighting, textiles, and interiors. From the late 1960s onwards, he exhibited widely and worked on a variety of interior design and architecture projects, including the interior design of the Ford Foundation headquarters (1967) in New York, the Georg Jensen Design Center (1968) also in New York, the interior to the American Restaurant in Kansas (1974), the interiors for Water Tower Place (1976) in Chicago, and the Windows on the World Restaurant (1976) atop the World Trade Center in New York.

In the 1960s, as the modernist movement became more expressive, Platner focused on a quieter aesthetic, wishing to create more graceful structures. In 1966 Platner, in collaboration with Knoll , unveiled the Platner Collection—a series of sleek modern chairs, ottomans and tables that rest on an intricately sculpted base of cylindrical steel rods replicating a moiré pattern. Requiring over 1,000 welds for one piece alone, the complex design is a close marriage of architecture and industrial design. Though Platner designed other pieces, the Platner Collection was his most renowned collection that ultimately made a name for himself in furniture design.

Planter received the Rome Prize in 1955 for his architecture designs and was inducted into Interior Design magazine’s Hall of Fame in 1985.

Platner passed away in 2006 at the age of 86.

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.
