[1] After graduating from the Höhere Graphische Bundes-Lehr- und Versuchsanstalt in Vienna, Gamerith initially worked at an armaments factory.
She subsequently began designing postcards, and worked as a graphic artist at the Schönbrunn Zoo, where she painted signs that described the animals.
[3][5] Living amidst the nature of Waldhausen, Gamerith's life was closely related to art.
Her earlier works centered on flower compositions, and later, she painted landscapes that included floodplains, tropical forests, and reefs.
For their joint effort to combine art and nature, Gamerith and her husband were honoured with the Konrad-Lorenz-Preis [de] (Konrad Lorenz Prize for Environmental Protection) in 1984.
