Guardigli was born in Ravenna. At 18 he enrolled in and attended the School of Fine Arts of Ravenna. During World War II he was drafted and served from 1943 until 1946 in the Regia Marina. After the war he returned to the School of Fine Arts, receiving his diploma in 1948. He enrolled in the School of Painting and Mosaics, also in Ravenna, graduating in 1951. From 1951 to 1955 he worked with the Gruppo mosaicisti of Ravenna and restored many mosaics. Also in 1951, at the end of November, he arrived in Paris to teach at the Ecole d'Art Italien as an assistant to the painter Gino Severini, founder and director of the school. Together with another mosaicist, his fellow Ravennan Lino Melano, he executed mosaic works for artists including Fernand Léger, Georges Braque, Marc Chagall, Jean Bazaine, and Raoul Ubac. He collaborated also on the mosaic for the façade of the Musée national Fernand Léger in Biot. In 1960 he executed, at the Colombe d'Or of Saint-Paul-de-Vence, a mosaic by the painter Georges Braque. From 1961 he had a studio in the artists' residence La Ruche at 2, passage de Dantzing in Paris, the place described by Lorenzo Viani in the book Parigi 1925, published by Fratelli Treves. In 1962, in another collaboration with Braque, he created the famous long fish tank of the Fondation Maeght in St Paul de Vence. His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections. The latter portion of his life was spent in an old people's rest home in Paris, where he died in 2008.
