Pietro Chiesa was a leading Italian Art déco designer, who trained in the Milan studio of the furniture designer and interior decorator Giovan Battista Gianotti after studying in Grenoble and Turin. In 1921 Pietro Chiesa opened Botega di Pietro Chiesa in Milan. At the 1925 "Exposition Internationale des Arts Décoratifs et Industriels Modernes" in Paris, Pietro Chiesa showed work for the first time. In 1927 Pietro Chiesa joined the designers Gio Ponti, Michele Marelli, Tomaso Buzzi, Emilio Lancia, and Paolo Venini to found Il Labirinto, which designed high-quality furnishings in the Novecento style. Pietro Chiesa chiefly designed glass objects featuring monochrome geometric patterns. In 1933 Botega Pietro Chiesa merged with Fontana Arte, which had been founded by Gio Ponti and Luigi Fontana. After the merger, Pietro Chiesa became artistic director of the new firm. Fontana Arte initially concentrated on making furniture and glass objects but in later years it became known primarily for lighting. Pietro Chiesa continued to design glass objects as well as furniture and lamps, treating glass as a precious material, using splinters of it and special cutting techniques. At the same time, Pietro Chiesa also created pure forms such as his 1932 glass table, which consists in a single bent strip of clear glass. In 1933 Pietro Chiesa designed the elegant, flute-like "Luminator" floor lamp of lacquered brass tubing, which provides indirect lighting.
