Angelo Mangiarotti Large Round Marble Onyx Vase Centerpiece for Knoll, Italy Label

Italian architect, designer, teacher and urban planner Angelo Mangiarotti was a leading light in the international design community from the 1960s onward. While he was an adherent of the rationalist principles of purity of line and simplicity of construction, he sought to imbue his designs for coffee tables, dining chairs, sconces and other furnishings with a sense of character and lightness of spirit that was often lacking in late-20th-century modernist architecture and design. 

Born in Milan, Mangiarotti studied architecture at Milan Polytechnic, graduating in 1948. Five years later, he won a visiting professorship at the Illinois Institute of Technology — beginning a peripatetic academic career that would see him teaching in numerous Italian institutions as well as in schools as far afield as Hawaii and Australia. He worked with Bauhaus eminences Ludwig Mies van der Rohe and met such greats as Frank Lloyd Wright and Walter Gropius. He returned to Italy in 1955 and would go on to work on numerous industrial, residential, commercial and civic projects in his home country, most notably a group of six railway stations in Milan.

As a designer, Mangiarotti and the development of his career embodies the evolution of modernism in the latter decades of the 20th century. In the late 1950s and early ’60s, after early experiments in plywood furniture and one-piece foam-core seating — including the 1110 lounge chair for Cassina — Mangiarotti began to design using more classic materials, from delicate, curvaceous blown-glass table lamps for Artemide to chandeliers with crystal links for Vistosi.

In 1971, Mangiarotti introduced what became his signature designs: a series of tables in marble and other stones that featured “gravity joints,” their legs held in place by the weight of the tabletop. Tables in his Eros collection have muscular proportions that anticipate the robust, overscaled lines of postmodern works that would appear 10 years later: His Eccentrico table, for example, is a striking assemblage in marble featuring a top that is cantilevered dramatically on a canted columnar base. 

But simplicity and practicality were consistently the primary watchwords of Mangiarotti’s designs. The purity and elegance of the objects he created offer a graceful counterpoint to a traditional decor, yet they have a singular sculptural presence that allows them to stand out powerfully in a modern interior.

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.
