Álvaro de Sá was an engineer and poet who originally wrote verbal poetry. In 1962, he began experimenting with language. In 1965, De Sá met Wlademir Dias Pino and intensified his experimentation with semiotic poetry. In 1967, he co-founded the Process/Poem Movement. He was the co-editor of the Ponto I and Ponto II movement journals. Extending his work outside Brazil, De Sá established creative dialogues with poets Edgardo Vigo in Argentina and Clemente Padín in Uruguay. In 1973, he partnered with Neide Dias de Sá to make film-poems. His published process-poems include "Alfaberto" (workbook) in 1966; "Poemas Comestíveis" (Edible Poems, a performance) in 1967; "Chaos" (playing object) in 1969; "12 X 9" in 1967 and "Poemics" (comics metalanguage) in 1991. His books of criticism include: "Vanguard Communication of Product," 1977 and "Vanguard Poetry in Brazil," 1983 (with Antônio S.L. Mendonça). He has exhibited at the São Paulo Biennial and other expositions and has published essays on semiotics and poetry in specialized journals and magazines. Álvaro De Sá died in October of 2001.
