Niobe lived most of her childhood in the interior of São Paulo by the countryside, but moved to the capital in 1932.
[2] At the age of sixteen she married a prominent communist militant, Joao Baptista Ribeiro Rosa.
When she moved into the city, Niobe began attending the Communist Party meetings and met many many of the left-wing intellectuals and politicians of that time.
[2] In 1951, Niobe separated from her first husband and married Alexander Bloch, a Czech intellectual and scholar.
During this period, a music label in London asked Alexander Bloch for permission to use one of Niobe's works to illustrate the Rolling Stones album.
Her art included figuratism, transitional works, flowers, masks, letterism, mechanism, abstractions, collages, reprography, and objects.
Niobe began to create original and extravagant pieces using washers, rulers, compasses, and other unusual objects.
The masks carry enigmatic images of ancient gods of her country, and are inspired by her ancestors to create graphic sings to represent symbols.
