Geraldo de Barros (1923 — 1998)
Geraldo de Barros was a Brazilian painter and photographer who also worked in engraving, graphic arts, and industrial design. He was a leader of the Concrete Art movement in Brazil, co-founding Grupo Ruptura, and was known for his trailblazing work in experimental abstract photography and modernism. According to The Guardian, de Barros was “one of the most influential Brazilian artists of the 20th century.” From 1954 until the 1960s, he was at the head of Unilabor, a company he founded to produce his inventive minimalist furniture.
