Argentine sculptor. His father was a sculptor, and Iommi studied in his father's workshop and attended metalwork courses. He was a founder-member of the ASOCIACIÓN ARTE CONCRETO INVENCIÓN and is one of the most representative Constructivist sculptors in Argentina. In 1954 he created Continual Forms (white concrete, 2.0*0.8*1.2 m), a sculpture for a house in La Plata designed by Le Corbusier. His highly formal work was characterized at first by an economy of means, rigorous logic and dynamic rhythms and tensions, with an intelligible and rational structure of form that was optimistic in tone. It was with such works that he won a gold medal in Brussels at the Exposition Universelle et Internationale in 1958, took part in the exhibition Concret Art at the Kunsthaus, Zurich, in 1958, and participated hors concours in the São Paulo Biennale in 1961 and Venice Biennale in 1964.
