Sonia Andrade (born 1935) is a Brazilian feminist and visual artist. She was born in 1935 in Rio de Janeiro in Brazil. She was one of the pioneers in video art in Brazil in the mid-1970s. Her video works use appropriation, humor, and political commentary to break down accepted visual codes. Andrade's body of work includes drawings, photography, objects,installation and mulit-channel video to achieve what she calls "the most important aspect of art-the relationship between the spectator and the object". 'Hydrogrammas' is her most famous piece of work which consist of hundreds of small objects that assemble into a sculpture, which was eventually displayed in National Museum of Fine Arts and later at the Museum of Contemporary Art of São Paulo.
