Rogelio Polesello was an Argentine painter, muralist, and sculptor. He was best known for making Op art (or optical art) known in Latin America. He won two Konex Awards; one in 1982 and another in 2012. He was born in Buenos Aires. Rogelio Polesello studied at the Escuela Nacional de Bellas Artes Manuel Belgrano and the Escuela Nacional de Bellas Artes Prilidiano Pueyrredón, both in Buenos Aires. In 1959, he joined the Asociación Arte Nuevo, founded by Aldo Pellegrini and Carmelo Arden Quin. The paintings he included in his first solo exhibition at the Galería Peuser (Buenos Aires, 1959) followed the aesthetics of Op Art and were based on Gestalt theories. Their geometric forms, generally in black and white, added to or subtracted from the whole according to perceptive principles that produced specific optical effects. Polesello died from a heart attack on 6 July 2014 in Buenos Aires. He was 75.
