Gabrielle Graessle was born in Zurich (Switzerland) in 1956 and has been fascinated by painting and drawing since she was a child. She studied for 5 years at the Zurich School of Art, where she graduated in graphic design. Her first exhibitions took place while she was still a student. During this time, she mainly produced black and white charcoal drawings in which she spontaneously captured her personal imagery. For 15 years she was represented in several galleries in Switzerland, and many of her charcoal drawings are in private and public collections.
In the early 2000s, she and her partner emigrated to France and later to Spain, where they worked on renovation projects for old houses. At that time, Graessle's means of expression were mainly drawings and sketchbooks.
