Lygia was born in Rio de Janeiro in 1931. As the wife of poet Augusto de Campos, sister of poet Ronaldo Azeredo, and sister-in-law of the poets Haroldo de Campos and José Lino Grünewald, she could not avoid living so intensely among the renewal of Brazilian poetry, and being in the constant presence of reunions and discussions in the innermost circles of concrete poets. Campos attended courses in literature at several universities in Rio and São Paulo (UFRJ, USP, PUC). She collaborated with Augusto in the literary research for the revaluation of the writer and artist Patricia Galvão (Pagu), the so-called "Muse of the Anthropophagy" (a modernist movement conducted by Oswald de Andrade). Rare and unpretentious in her poetry, Campos could be classified in the category of "bissextile poets," as labeled by poet Manoel Bandeira in a celebrated anthology of poets of small productivity and high quality. Some of her poems were published by Omar Khouri and Paulo Miranda in the equally rare magazine "Zero À Esquerda" (Zero at Left) and also in the famed "Código" from Bahia. Artist Regina Vater included Campos’ poems in "The Book of Hope," part of her installation at ArtPace in San Antonio, Texas.
