Italian designer Harry Bertoia is best known for his work with industrial wire rods. Working for Florence Knoll, and contributing to the work of Eero Saarinen, Bertoia and his contemporaries are largely responsible for the incredible shift in design and style of the mid-twentieth century.
In 1943, he moved to California to work for Charles and Ray Eames; he worked for them until the war ended in September 1945. In 1950, he established a studio, and to work with Hans and Florence Knoll. During this period he designed five wire pieces that became known as the Bertoia Collection for Knoll. Among them the Diamond Chair, a fluid, sculptural form made from a molded lattice work of welded steel. In Bertoia's own words, "If you look at these chairs, they are mainly made of air, like sculpture. Space passes right through them."
