Hélio Oiticica (1937–1980) was among twentieth-century Brazil’s most significant artists, with a multifaceted practice that included painting, sculpture, installation, performance, filmmaking, and writing. Oiticica was a leading member of Grupo Frente (an association of concrete artists) and, in 1959, he co-founded the neoconcrete movement with artists and poets including Lygia Clark, Lygia Pape, and Ferreira Gullar. Oiticica was a 1970 Guggenheim Fellow, and today his work is held in collections across the world, including at MoMA and the Tate Modern.
