Harry Bertoia would have been 100 this year. It would have been a well-earned birthday party for this versatile artist who created a chair design that was iconic in the history of 20th-century design. Born in Italy, he moved to the United States to continue his studies at the Cranbrook Academy of Art. This was how he had his pivotal meeting with Florence and Hans Knoll, who later asked him to design an entire line of furniture. He set the stage with the Diamond Chair in 1952, with a shape that was both ergonomic and sculpted. It was so successful that Knoll never stopped producing it. And now, a new generation takes over to bring furniture that is both beautiful and functional to contemporary interiors.
