Dumas was born in Cape Town in 1953 and grew up on her family’s vineyard at the Kuils River, in the south west of South Africa.
In the seventies she studied “Art” at Michaelis School of Fine Arts. Afterwards she got a scholarship to the Netherlands for two years,
because of the language. Language has therefore an importance in her work. She gives striking titles to her exhibitions and her pieces.
Dumas’ style leans to expressionism and conceptual art. Her paintings and watercolors are almost erotic.
She tests the boundaries of humanity in her male but most of all in her female work, where her subjects frequently take obscene poses that are very explicit.
Since she uses mostly photographic sources, she has a large collection of self-taken snapshots. We can notice this in her work.
