Kyoto coffee table by Gianfranco Frattini for Knoll, 1970s.

Gianfranco Frattini is widely regarded as a mid-century master of Italian modern design. He was an award-winning architect and designer, and specialized in creating furniture and decor that is both decorative and practical — Frattini’s vintage desks, armchairs, nesting tables and other works are celebrated for their sophisticated merging of function and form.

Born in Padua in 1926, Frattini studied architecture at the Polytechnic University of Milan. He later apprenticed with his teacher and mentor, Gio Ponti. Through Ponti — arguably the most important figure in 20th-century Italian architecture and design — Frattini met many notable modernist designers such as Oscar Niemeyer and Le Corbusier, but an introduction to famed Italian entrepreneur Cesare Cassina would prove incredibly significant in helping launch his career.

During the mid-1950s, Frattini began to collaborate with Cassina’s eponymous company. He designed the brand’s acclaimed leather and walnut Model 849 lounge chair — a winner of the Compasso d’Oro award — the Marema nesting tables and the iconic Sesann collection. The latter, an enduring 1970s suite of impossibly welcoming leather-covered seating, is now produced by Tacchini. In addition to Cassina, Frattini created furniture and lighting for other manufacturers such as Bernini, Arteluce, Artemide, Knoll and more.

While many of his designs incorporate glass, tubular steel and other materials, Frattini loved working with wood. The sculptural Albero bookcase — an innovative floor-to-ceiling structure made in walnut that swings on a 360-degree vertical swivel axis — is a striking example of Frattini’s dedication to traditional woodworking techniques. In the early 1970s, he traveled to Japan with friend and collaborator Pierluigi Ghianda — a master Milanese cabinet maker — in order to study the work of artisans in Kyoto. The trip inspired his design of the Kyoto table, a work of solid beech with Canaletto walnut inserts that is part of the permanent collection of the Milan Triennale’s Design Museum. The Kyoto and Albero have been revived by Poltrona Frau.

Frattini’s designs are in the permanent collections of prestigious museums such as the Museum of Modern Art and the Cooper Hewitt, Smithsonian Design Museum.

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.
